metal clad switchgear HXGN

Armored shift type AC metal closed switchgear (hereinafter referred to as switchgear)---Metal clad switchgear

 is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete power distribution device. 

Receiving and distributing electric energy as power plants, substations and industrial and mining enterprises.

 It can control, protect and detect the circuit, and can also be used in the place of frequent operation.

 This switchgear conforms to GB/T11022-1999, GB3906-1991 and DL 404-1997 and other standards.

HXGN口-12( metal clad switchgear) Overview

HXGN 口-12(SF6) Unit type AC metal-enclosedring main unit(hereafter refer to as ring net cabinet) is a new generation 

of high- pressure electric appliance product designed and developed independently by our own company according to

 the requirement of the domestic agricultural electricity and the city net transformation after introduction of overseas advanced technology. 

Each technical performance index completely reaches the lEC298 and GB3906 standard.

The circuit breaker or the VD4-Svacuum circuit-breaker divide into two kinds: be operated manually and electrically according to the operating mode.

The cabinet body is riveted after processed by numerical control machine tool with reliable mechanical interlocking and the misoperating prevention function. 

The protection grade reaches IP3X.

This product has the remarkable characteristics such as:

 the small volume, light weight, artistic appearance, simple operation, long life, high parameter with no pollution and little maintenance.

Use environmental conditions:

  1. The altitude should not exceed 2000m

  2. Surrounding air temperature:-25℃+40℃

  3. Relative temperature:the dialy average value is not higher than 95%,the monthly average value is not higher than 90%

  4. Surrounding air without caustic gas or ignitable gas, steam and other obvious pollution

  5. Without fierce vibration
