Combined Fixed Indoor AC Metal-clad switchgear XGT8-12
XGT8-12 Combined and Fixed Indoor AC Metal-clad switchgear (hereafter referred to as switchgear) is a new generation of HV electric product, researched, designed and developed by ourselves. And it is the indoor switchgear, using 12kV three-phase AC rated voltage and 50HZ rated frequency.
This switchgear is the 50HZ, 3-10kV indoor complete equipment of single busbar or sectioning busbar used to distribute electric power. It has the function of breaking short circuit, monitoring and protecting circuit. It can be combined randomly or used with HKT1 RMU. And it is wildly used in the substation and places with less maintenance, but frequent operation.
Product feature of Combined Fixed Indoor AC Metal-clad switchgear XGT8-12 :
a. It is small in size, less in space. The enclosure of switchgear are imported and bent zinc plate coated aluminum, with universal spare parts and short production period. The protection level of its enclosure is IP3X. And the decompression passages are on the top and back of the switchgear. Besides the primary components is mounted on the side.
b. It adopts "Five protection" interlock mechanism. The function of "Five protection" interlock and operating mechanism have been integrated into a separate interlock operating mechanism module. The interlock is easy and reliable. And the disconnector and earthing switch is easily operated. At the same time, the arrangement inside the cubicle is simple.
