For a Yueqing reactor manufacturer shortlist, compare Hongcheng, EAG, Jiuyan, Jinluo, Fengle, Tongmai, Suheng, Yadulan, PEOPLE and FATO. Each company publishes a reactor range and a Yueqing connection on an official website. The important comparison is not the largest current label: it is the reactor duty, inductance, harmonic current, insulation, thermal design, short-circuit withstand and the documents attached to the exact model.
“Reactor” covers several different products. A series reactor sits with a capacitor bank to detune the branch and limit inrush current. An input or output reactor sits on the AC side of a variable-frequency drive. A DC smoothing reactor sits in a converter DC link. A current-limiting reactor limits fault or inrush current, while a filter reactor is designed around a specific harmonic and impedance curve. These products can look similar, but their current waveforms, insulation and thermal duties are not interchangeable. Decide which circuit duty you are buying before comparing factories. If the reactor will sit in a compensation or drive assembly, our power capacitor guide, switchgear guide and VFD guide can help define the surrounding scope.
How this list was selected: Official product, catalogue and contact pages were reviewed on 24 October 2026. This is a research shortlist, not a quality, price, certification, export or “best” ranking. It does not imply that BottomRace has audited every factory or verified every published rating. Confirm the legal entity, production site, exact model and current supporting documents before ordering. A reactor name, a catalogue photograph or a published capacitor rating does not prove the performance of the specific unit you will receive.

Manufacturer profiles and sourcing questions
1. Zhejiang Hongcheng Electric Co., Ltd.
Short name: HONGCHENG
Published location: Xuezhai Industrial Zone, Liushi, Yueqing
Hongcheng presents itself as a Yueqing manufacturer focused on power quality and harmonic treatment. Its reactor category separates the HCCKSG low-voltage series reactor from the CKSC high-voltage dry-type series reactor. The CKSC description places the reactor in series with a shunt capacitor bank to limit inrush current, suppress harmonic current and reduce switching overvoltage. That is a system-function description, not a model datasheet: ask for the inductance, rated current, reactor percentage, insulation level, temperature-rise basis, losses and routine-test record for the exact catalogue number. The published address is Xuezhai Industrial Zone in Liushi.
Before requesting a quote: Provide the system voltage, capacitor bank voltage and kvar per step, measured harmonic spectrum, required reactor rate, continuous and short-time current, switching arrangement, ambient conditions and installation clearances. Ask for the exact HCCKSG or CKSC model, inductance and tolerance, winding conductor, core construction, insulation class, temperature rise, losses, noise, terminal layout, drawing, routine tests and model-level standard reference.

2. Yunrong Electric Technology (Zhejiang) Co., Ltd.
Short name: EAG
Published location: No. 86 Zhenxing Street, Nanjie Village, Wengyang, Yueqing
Yunrong, which presents the EAG brand, states that it was founded in 2018, operates a 6,000 m² factory and manufactures low- and high-voltage reactors, power capacitors, intelligent capacitors, compound switches and controllers. Its official product centre shows EPCKSG low-voltage series reactors and EPACL/OCL variable-frequency-drive reactors as separate families. The distinction matters because a capacitor-series reactor is selected with the capacitor bank and its harmonic duty, while an input or output reactor is selected against the drive, motor cable and electrical environment. The contact page gives No. 86 Zhenxing Street in Wengyang.
Before requesting a quote: For an EPCKSG enquiry, send the capacitor voltage and kvar, reactor rate, harmonic data and switching method. For EPACL/OCL, send the drive rating, input voltage and frequency, motor current, cable length, switching frequency and whether the reactor is for the input or output side. Ask for the exact model, inductance, voltage drop, rated and short-time current, insulation system, temperature rise, losses, drawing, routine tests and the intended installation environment.

3. Zhejiang Jiuyan Electric Power Technology Co., Ltd.
Short name: JIUYAN
Published location: Xinguang Industrial Zone, Liushi, Yueqing
Jiuyan states that it develops and manufactures high- and low-voltage reactors, capacitors, intelligent capacitors, compound switches and controllers. Its reactor range is unusually easy to separate by duty: CKSC high-voltage dry-type series reactors for capacitor banks; ACL/OCL three-phase input and output reactors for variable-frequency drives; and DCL DC smoothing reactors for converter DC links. The company also publishes input and output filters in the same category. Keep the reactor and filter scopes separate, because a reactor alone does not provide the attenuation of a complete sine-wave or EMC filter.
Before requesting a quote: State whether the requirement is CKSC, ACL, OCL, DCL or a complete filter. Provide the system voltage, frequency, fundamental current, harmonic spectrum, drive or converter topology, switching frequency, DC-link data where applicable and required inductance or voltage drop. Ask for the exact model, continuous and short-time current, insulation level, temperature rise, losses, noise, terminal arrangement, drawing, routine-test record and installation instructions.

4. Zhejiang Jinluo Electric Technology Co., Ltd.
Short name: JINLUO
Published location: He'ao Industrial Zone, Liushi, Yueqing
Jinluo describes itself as a manufacturer of reactive-power compensation components and publishes a dedicated reactor category headed by the CKSG low-voltage series reactor. Its wider range also includes intelligent capacitors, controllers, compound switches, contactors, capacitors and disconnectors. That makes it relevant to a buyer assembling a complete compensation branch, but the reactor quotation still needs to stand on its own electrical data. Do not infer a reactor rating from the capacitor rating alone; the reactor percentage, capacitor voltage and expected harmonic current determine the actual duty.
Before requesting a quote: Send the system voltage, capacitor rated voltage and kvar per step, required reactor percentage, measured harmonic spectrum, switching device, continuous current and expected short-time current. Ask for the exact CKSG model, inductance and tolerance, conductor material, core construction, insulation class, temperature rise, losses, dimensions, terminal layout, mounting distance and routine-test record.

5. Yueqing Fengle Electric Co., Ltd.
Short name: FENGLE
Published location: No. 59 Liule Road, Liushi, Yueqing
Fengle states that it manufactures transformers, reactors, intelligent compensation equipment, filters and voltage stabilisers. Its official reactor category lists the CKSG low-voltage series reactor, three-phase input/output reactor, DC reactor and CKSC high-voltage dry-type series reactor. This breadth is useful for a project that needs several reactor types, but the buyer should not use one generic reactor datasheet across all four families. Capacitor-series, drive-input, drive-output and DC-link reactors have different current waveforms, insulation and thermal requirements. The contact page gives No. 59 Liule Road in Liushi.
Before requesting a quote: Identify the reactor family first, then provide the circuit voltage, fundamental current, harmonic spectrum, capacitor kvar or drive rating, switching frequency, duty cycle and ambient conditions. Ask for the exact model, inductance, voltage drop, current ratings, insulation level, temperature rise, losses, noise, terminal layout, outline drawing, routine tests and the standard applied to that model.

Those figures belong to the published ACL range and should not be copied to every reactor the company offers. Its OCL and sine-wave reactor pages address output-side and long-cable duties separately. The contact page gives Zhiguang Industrial Zone A in Liushi.
Before requesting a quote: For an ACL or OCL reactor, send the drive model and rating, input voltage, motor current, cable length, permissible voltage drop, switching frequency, ambient temperature and enclosure conditions. For a sine-wave reactor, state the required output waveform, cable length and motor insulation requirement. Ask for the exact model, inductance, current rating, voltage drop, insulation class, temperature rise, losses, noise, dimensions, wiring diagram and routine-test record.

Short name: SUHENG
Published location: No. 58 Nanyang Road, Zhiguang Industrial Zone, Liushi, Yueqing
Suheng states that it is based in Liushi and manufactures capacitors, controllers, switching devices, filters, reactive-power equipment and low-voltage series reactors. Its company page says that the reactor range includes low-voltage series reactors, dry-type air-core reactors and starting reactors, while its dedicated CKSG page presents the low-voltage series reactor for capacitor compensation. This is a useful local source for a compensation bill of materials, but the product page is brief. Obtain a model drawing and electrical schedule rather than relying on the catalogue title alone.
Before requesting a quote: Provide the capacitor voltage and kvar, reactor percentage, system voltage and frequency, harmonic spectrum, switching arrangement and expected continuous current. Ask for the exact CKSG model, inductance and tolerance, winding material, core type, insulation class, temperature rise, losses, noise, dimensions, terminal layout, mounting requirements and factory test record.

The CKSG page describes the reactor as part of a low-voltage compensation branch, limiting harmonic and switching stress on the capacitor. The XD1 page describes a cast-resin dry-type reactor for limiting capacitor inrush current and cites GB/T 1094.6-2011 and GB/T 19212.1-2016. Those are different duties even though both sit near a capacitor. The company's wider range covers capacitors, controllers, compound switches, APF and SVG equipment. The published address is No. 83–87 Zhongshan Avenue in Madao Village, Liushi.
Before requesting a quote: State whether the reactor is intended for series detuning, inrush limitation or another duty.

Reactor quotation and design checklist
A reactor quotation can look complete while leaving out the duty that determines its temperature, losses and life. Give every supplier the same electrical schedule, harmonic data and installation information, then ask for a model-specific selection rather than a price for a generic “series reactor”.
| Include in your enquiry | Ask each supplier to confirm |
|---|---|
| Circuit duty | Capacitor-series, detuning, current-limiting, VFD input, VFD output, DC smoothing or filter service; explain why the selected family fits the actual circuit. |
| System data | Nominal and maximum voltage, frequency, phase arrangement, drive or converter topology, switching device and the point at which the reactor will be installed. |
| Electrical ratings | Inductance and tolerance, fundamental current, harmonic current, continuous current, short-time current, short-circuit withstand, voltage drop and required reactance or reactor percentage. |
| Harmonic duty | Measured or calculated spectrum, dominant orders, harmonic current factor, resonance study and the assumptions used to select the core, winding and cooling. |
| Insulation | System voltage, rated insulation level, dielectric test, winding insulation class, creepage and clearance, impulse requirement and any high-altitude correction. |
| Thermal design | Ambient temperature, enclosure conditions, altitude, duty cycle, allowable temperature rise, loss calculation, cooling method and the hottest-spot assumption. |
| Construction | Copper or aluminium winding, core or air-core construction, lamination and clamping, impregnation or casting, terminal material, terminal sequence and corrosion protection. |
| Mechanical data | Dimensions, mass, mounting centres, clearances around adjacent reactors, orientation, cable or busbar connection, lifting points and seismic or vibration requirements where relevant. |
| Noise and losses | Published loss figures, measurement basis, sound level at a stated distance, core vibration and any enclosure effect that changes the thermal or acoustic result. |
| Coordination | Capacitor, contactor or switch, fuse or breaker, drive, filter, cable and earth connection reviewed as one circuit; do not approve the reactor in isolation. |
| Standards and records | Exact standard references for the offered family, routine tests, inductance check, winding resistance, insulation and withstand tests, temperature-rise evidence and serial-number-linked records. |
| Commercial identity | Legal manufacturer, seller, production site, country of origin, warranty, document revision, spare-parts route and the technical person who approves the final selection. |
Do not select a reactor from the capacitor kvar alone. The voltage seen by the capacitor, the reactor percentage, the harmonic spectrum and the switching method all change the current and losses in the reactor. A 7% reactor is not a universal accessory for every capacitor bank, and a reactor designed for a 50 Hz sinusoidal current may be unsuitable for a drive output with a high switching-frequency ripple. Ask the supplier to show the calculation for the actual circuit.
Separate a reactor from a filter or a complete assembly. An ACL reactor reduces voltage distortion and inrush effects at a drive input, but it is not a complete EMC filter. An OCL reactor is not a sine-wave filter unless the supplier publishes the complete filter assembly and its performance. A CKSG reactor is not a complete capacitor bank. The enclosure, capacitor, switching device, protection, controller, busbars, cooling and routine test must be specified as separate lines in the quotation.
Treat short-circuit and harmonic current as design inputs. A reactor can carry a substantially higher current during a fault or a harmonic-rich duty than its fundamental current label suggests. Confirm the short-time withstand, the thermal current rating and the force withstand of the winding and clamping. For a drive circuit, include the motor cable length, switching frequency and DC-link or output-filter arrangement. For a capacitor circuit, include the measured harmonic spectrum and the switching inrush condition.
Keep the installation boundary visible. Reactors are magnetic components; adjacent steel, closed metal enclosures and other reactors can change inductance and temperature rise. Ask for the required clearances and the effect of the intended mounting arrangement. A bench test in open air does not automatically represent the thermal performance inside a cabinet.
What to check during a reactor factory visit
Arrange the visit after the supplier has identified the exact model and production site. Ask which operations are in-house: conductor winding, core cutting and stacking, insulation, impregnation or casting, terminal assembly, drying, electrical test and packing.
- Trace the magnetic circuit: ask to see the core lamination, stacking, clamping and insulation for the quoted design. Confirm the core material and construction against the approved drawing rather than accepting a generic sample.
- Review the winding: check conductor specification, winding direction, layer insulation, transposition, terminal joints and the method used to control inductance and resistance. Ask how the factory prevents mixed conductor sizes or turns counts.
- Check impregnation or casting: verify the resin or varnish system, curing or drying record, void control and the method used to protect the winding from moisture and mechanical movement.
- Watch the tests: request inductance, winding resistance, insulation resistance, dielectric withstand and any turn-to-turn or partial-discharge test applicable to the product family. Record the instrument calibration and serial-number link.
- Review thermal evidence: ask how the quoted temperature rise was established for the actual current waveform, harmonic factor, enclosure and ambient temperature. A temperature label on a similar model is not a model-specific calculation.
- Inspect the mechanical build: check clamping pressure, terminal torque, creepage, clearances, corrosion protection, lifting points, mounting feet and the marking of terminals and winding direction.
- Check the records: ask for the approved drawing, bill of materials, routine-test record, nameplate data, packing list and warranty route. Link the documents to the serial number or batch.
- Confirm the entity and site: verify the legal manufacturer and production address for the reactor, and for any capacitor, drive, filter or assembly supplied with it. If a group has several plants, ask which site will wind, assemble and test the offered unit.
- Keep the limits of a visit clear: a factory visit provides observations and a document trail; it does not replace a design study, type test, certification review or independent product testing.

Questions reactor buyers ask
What is the difference between a series reactor and a current-limiting reactor?
A series reactor is normally connected with a capacitor branch to change the impedance and reduce harmonic or inrush stress. A current-limiting reactor is selected primarily for its impedance under fault or inrush current. The names overlap in the market, so compare the actual circuit duty, current waveform and required short-time withstand rather than the catalogue title.
Can I use the same reactor on a VFD input and output?
No. Input reactors are selected against the supply, drive rectifier, harmonic current and voltage drop. Output reactors see a pulse-width-modulated current with high-frequency components and must be designed for that ripple and insulation stress. A sine-wave filter is a further assembly, not just an output reactor. Keep the three scopes separate.
Is a 7% reactor suitable for every capacitor bank?
No. The reactor percentage must be selected with the measured harmonic spectrum, capacitor voltage rating, bank configuration and resonance target. A 14% design is not automatically better than a 7% design; each changes the voltage at the capacitor terminals and the harmonic current seen by the reactor. Ask for the calculation rather than copying a percentage from another site.
Why does the reactor need a harmonic current rating?
The fundamental current alone does not describe the heating and force in a reactor. Harmonic current increases copper and core losses and can excite additional noise or vibration. The supplier should state the harmonic spectrum or harmonic factor used for the thermal design and confirm the short-time and fault-current assumptions.
Does a higher inductance always mean better performance?
No. Higher inductance can reduce a particular harmonic current or inrush condition, but it also changes voltage drop, control response, losses and the voltage seen by a capacitor. The correct value depends on the circuit objective. A reactor that is oversized for one duty can create a new problem in another part of the system.
What documents should I request with a reactor quotation?
Ask for the exact model drawing, inductance and tolerance, current ratings, insulation and temperature-rise data, loss and noise data, terminal arrangement, installation clearances, applicable standards, routine-test plan and a sample test record linked to a serial number. For a drive or capacitor assembly, request the system calculation and the bill of materials as well.
Are these companies ranked by quality, price or export volume?
No. This is a research shortlist based on published product and location information. It is not a quality, price, certification, export or “best” ranking. The article does not establish that every company manufactures every reactor family at the stated address, and BottomRace has not audited every factory for this list.
