Product Features

● Main raw materials: High‑quality double‑sided roughened polypropylene film, aluminum foil, and benzyl toluene (or PEPE) are used, enhancing the product’s electrical performance.
● Internal Fuse: Featuring a proprietary technology‑based internal fuse and an element‑isolated structure, this design completely eliminates the risks of fuse non‑operation, false tripping, and cascading explosions, ensuring greater safety and reliability for the capacitor.
● Discharge resistor: Each series section is equipped with a discharge resistor. High‑quality, high‑voltage glass‑frit‑coated resistors ensure that, after the power supply is disconnected, the residual voltage of the capacitor drops from 2Un (peak voltage) to below 50 V within 10 minutes, thereby guaranteeing safety.
● Advanced core‑assembly assembly line: Processes ranging from component winding, dielectric‑strength screening, internal fuse assembly, core pressing, core wrapping, to core boxing are all carried out on a mechanized assembly line, ensuring the quality of core assembly.
● CNC‑controlled automatic tungsten inert gas (TIG) pulsed welding: used for welding capacitor housing seams, box wall–lid seams, and suspension lugs to the housing, ensuring welds that:
The seams are neat, smooth, and aesthetically pleasing, securely sealed with no leaks.
● A proprietary pressurized oil‑impregnation process is employed, significantly enhancing the capacitor’s partial discharge performance.

● Altitude shall not exceed 2,000 meters (corrections shall be applied for altitudes above 2,000 meters in accordance with the relevant standards).
● Ambient temperature: -40 to +50°C
● The installation location shall be free from severe mechanical vibration, harmful gases and vapors, and conductive or explosive dust.
● Continuous operating voltage: 1.0Un; the maximum long-term overvoltage shall not exceed 1.1Un.
● Steady-state overcurrent (including harmonic currents) shall not exceed 1.3In.

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.
