Industrial capacitor products
Product lines spanning a wide range of applications — each engineered to the exacting demands of its application.
High-Voltage Capacitors

Single-Phase Single-Bushing High-Voltage Capacitors
Single-bushing capacitors for single-phase shunt compensation and power-factor correction in AC systems.

Single-Phase Double-Bushing High-Voltage Capacitors
High-voltage capacitors for single-phase shunt compensation in AC systems; confirm the bushing arrangement for each model.

Three-Phase High-Voltage Capacitors
Three-phase integrated unit for centralized reactive power compensation in three-phase power systems.
Induction Heating Capacitors

Air-Cooled Induction Heating Capacitors
Natural or forced air cooling for low-to-medium power induction heating equipment.

Single-Circuit Water-Cooled Induction Heating Capacitors
Single water cooling channel with compact structure, for medium-power continuous-load applications.

Double-Circuit Water-Cooled Induction Heating Capacitors
Dual independent water cooling channels with enhanced thermal dissipation, for high-power, high-thermal-load sustained operation.
Special Application Capacitors

High-Frequency Metallized Film Capacitors
Metallized film capacitors for high-frequency power-supply resonant-circuit selection; ratings and construction require model-specific confirmation.

UHVDC Circuit Breaker Application Capacitors
Capacitor models for selection in UHVDC circuit-breaker modules; confirm branch duty against the project circuit.

VSC-HVDC Application Capacitors
DC support and filtering capacitors for MMC submodules in VSC-HVDC transmission systems.

DC-DC Converter Application Capacitors
DC support and filtering capacitors for DC-DC converter applications.

Rail Transit Traction Power System Application Capacitors
DC support and filtering capacitors for traction and auxiliary converters in locomotives, metro, and light rail systems.

Grounding Protection Capacitors
Capacitors for protection-circuit selection in induction heating power supplies; confirm grounding-protection duty and wiring by model.
