Product Overview

KGC high-voltage shunt capacitor switchgear is currently the most widely used reactive power compensation and filtering device. It typically comprises a shunt capacitor bank, series reactors, vacuum contactors, disconnect switches, controllers, surge arresters, discharge coils, and protective and measuring equipment, as shown in the figure. The equipment is primarily employed in three-phase AC power systems at voltage levels of 6 kV, 10 kV, 35 kV, and 110 kV.

Among these components, the capacitor bank primarily supplies sufficient reactive power; the series reactor bank mainly limits inrush currents during capacitor switching and simultaneously absorbs specific harmonic currents from the system; vacuum contactors facilitate the switching of the capacitor bank; disconnect switches serve as isolation points for maintenance; the controller regulates the contactors based on set control objectives (voltage, power factor, and reactive power); surge arresters protect the capacitor bank from operational overvoltages; discharge coils ensure that, within a short time after the capacitor bank is de‑energized, any residual charge on the capacitor terminals is fully discharged, thereby preventing hazardous overvoltages during subsequent re‑energization; common protective measures for capacitors typically include overcurrent, overvoltage, undervoltage, and unbalance protection.

Low Voltage Power Capacitor

Low-voltage dry-type shunt capacitors are energy‑saving devices used for power factor correction in low‑voltage power systems operating at 50 Hz or 60 Hz. They reduce reactive power losses and improve voltage quality. The KD‑H dry‑type eco‑friendly capacitor is manufactured using advanced German technology in a Class 100 cleanroom environment. Under vacuum conditions of 10–3 bar, the components are heated while protective gas is injected. This process effectively removes air and moisture from within the capacitor, preventing electrode oxidation and localized discharge. Following this sophisticated manufacturing sequence and rigorous factory acceptance testing and quality assessments, the capacitors achieve exceptional stability and an extended service life. Depending on the application, they are available in single‑phase and three‑phase configurations.

Original Imported Low Voltage Capacitor

The original imported MOKN series capacitors are highly popular in the Chinese market thanks to their proprietary technology. During production, these capacitors are filled with nitrogen (N2), and they incorporate a unique SINECUT grooving process along with a distinctive metal‑treatment technique. Moreover, their optimally positioned internal core ensures that the device’s capacitance remains stable even under the severe stress of high‑voltage AC surges and negative pressure conditions. This hallmark feature makes the MOKN series particularly well suited for applications involving controlled equivalent DC currents and surge protection.

Low Voltage Intelligent Capacitor

The KD‑Z series intelligent low‑voltage power capacitors are a next‑generation reactive power compensation device designed for 0.4 kV low‑voltage distribution networks, delivering high efficiency and energy savings, reducing line losses, and improving the power factor and power quality. They consist of an intelligent measurement and control unit, a synchronous switching circuit, a line protection unit, and low‑voltage power capacitors. These units replace conventional automatic reactive power compensation systems that rely on discrete components—such as smart controllers, fuses, composite switches or mechanical contactors, thermal relays, low‑voltage power capacitors, and indicator lights—wired together inside and on the surface of switchgear cabinets. By eliminating the bulky, unwieldy design of traditional systems, this new generation of low‑voltage reactive power compensation equipment offers superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost savings, enhanced flexibility in application, simplified maintenance, extended service life, and higher reliability, thereby meeting the increasingly stringent requirements of modern power grids for reactive power management.

Low-Voltage Anti-harmonicIntelligent Power Capacitor

The KD‑ZLK harmonic‑suppression intelligent power capacitor is equipped with a custom segmented LCD display that provides real-time readings of three-phase bus voltage, three-phase bus current, three-phase power factor, frequency, the number of capacitor banks and their switching status, active power, reactive power, total harmonic distortion of voltage, and capacitor temperature.
