Product Description

HXGN -12(SF6) Unit type Ac metal-enclosed ring main unit(hereafter refer to as ring net cabinet) is a new generation of highpressure electric appliance product designed and developed independentliy by our own company according to the reguiremenof the domestic agricultural electricity and the city net transformation after introduction of overseas advanced technology. Eachtechnical performance index completely reaches the lEC298 and GB3906 standard.The loop-net cabinet s main switch, the operating mechanism and the components is made of the Corporation originalpiece or the SFL-12/24 switch equipment imported overseas and ass-embled at home.  The circuit breaker or the VD4-Svacuum circuit-breaker divideinto 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 themisoperating prevention function. The protection grade reaches iP3X.This product has the remarkable characteristics such as thesmall volume,light weight, artistic appearance, simple operation, long life, high parameter with no pollution and little maintenance.
