High Voltage Indoor Fixed or Withdrawable Vacuum Circuit Breaker (VCB)
Product Description:
VSG indoor vacuum circuit breakers are suitable for indoor 12/24kV switchgear, and are suitable for controlling and protecting power grid equipment, industrial and mining enterprises, and other transmission and distribution systems as their protection and control units.
Can be used in conjunction with KYN28 (GBM) type switchgear. The products comply with IEC standards, including VCB truck, isolation truck and fuse truck etc.
1. This series of VCB adopts an integrated design of operating mechanism and VCB body, with a reasonable and compact layout.
2. This series of VCB adopts a vertical insulation room, which can effectively prevent damage to VIS due to external factors.
3. There are two types of installation units, fixed and withdrawable, which can meet the different assembly requirements of switchgear and circuit breakers.
Suitable for various places:
1. Control and protection of industrial electrical equipment.
2. Mining enterprises.
3. Power plants.
4. Substation.
It can be fixed in the switchgear or installed on a handcart.
