Product Overview

XGN15-12 modular AC metal enclosed sulfur hexafluoride ring network switchgear (hereinafter referred to as ring network cabinet) is a new generation of high voltage electrical appliances successfully designed and developed by our company according to the requirements of domestic rural power and urban power network transformation by introducing advanced technology. Through strict type test and long-term operation assessment, all technical performance indexes have reached IEC298 and GB3906 standards. The main switch, operating mechanism and components of the ring main unit are SFL-12/24 type switchgear manufactured by ABB or FLN36-12D type SF6 switchgear manufactured in China. The original HAD/US type SF6 circuit breaker or VD4-S type vacuum circuit breaker manufactured by ABB can also be installed according to user needs. The operation modes are divided into manual and electric. The cabinet body is made of imported aluminum coated zinc plates processed by CNC machine tools and riveted. The protection level reaches | P3X, and it has reliable mechanical interlocking and anti misoperation functions. This product is characterized by small volume, light weight, beautiful appearance, simple operation, long service life, high parameters, no pollution, less maintenance, etc.

Low voltage power capacitor

KD-H dry environment-friendly capacitor adopts advanced German technology and is manufactured in an environment with a hundred level purification level. The element is heated under 10-3 Bar vacuum condition and the protective gas is injected at the same time. In this way, air and moisture can be discharged from the capacitor, thus avoiding electrode oxidation and partial discharge. Through this complex process and strict factory inspection and quality evaluation, it is ensured that the capacitor has excellent stability and long service life. It can be divided into single-phase and three-phase according to different occasions.

Original imported capacitor

MOKN series capacitors imported from Germany are very popular in the Chinese market because of their unique technology. Nitrogen (N2) filling, special SINECUT slotting technology and unique metal processing technology, as well as the most reasonable inner core position, are used in the production process of capacitors to ensure that the capacitance of equipment remains unchanged under the impact of large AC high-voltage negative pressure. This unique feature of MOKN series products makes it particularly suitable for applications in controlling equivalent DC current and surge.

Low voltage intelligent capacitor

KD-Z series intelligent low-voltage power capacitor is a new generation of reactive power compensation equipment for 0.4KV low-voltage power grid, which can save energy efficiently, reduce line loss, and improve power factor and power quality. It consists of intelligent measurement and control unit, synchronous switch circuit, line protection unit and low-voltage power capacitor. It replaces the conventional automatic reactive power compensation device composed of intelligent controller, fuse, composite switch or mechanical contactor, thermal relay, low-voltage power capacitor, indicator light and other loose parts connected by wires in the cabinet and on the cabinet surface It has changed the bulky and cumbersome structure mode of the traditional reactive power compensation device, so that the new generation of low-voltage reactive power compensation device has the characteristics of better compensation effect, smaller volume, lower power consumption, cheaper price, more cost saving, more flexible use, more convenient maintenance, longer service life, and higher reliability, which adapt to the higher requirements of modern power grid for reactive power compensation.

Anti harmonic intelligent power capacitor

KD-ZLK anti harmonic intelligent power capacitor adopts customized segment LCD display, which can display three-phase bus voltage, three-phase bus current, three-phase power factor, frequency, capacitor circuit number and switching status, active power, reactive power, total harmonic voltage distortion rate, and temperature of electric container in real time.
