Product Description

Product Description

HXGNO-12(SF6)Unit type ACmetal-enclosed ringmain unit (hereafter refertoasring network cabinet) isa newgeneration ofhigh-pressure cle ctric 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 overscas advanced technology. Ench technical performance index completcly reaches the IEC298 and GB3906 standard.
The loop-net cabinets main switch, the operating mechanism and the components is made of the ABB Corporation original piece or the SFL-12/24 switch equipment imported overseas and assembled at home. We can also install the ABB Corporation original piece of HAD/US type SF according to the request of users. 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 1P3X.
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.
