KYN28 10kv 11kv 12kv 13.8kv Cubicle Type Gas Insulated Switchgear
1. kyn28 12 type 10kv 11kv 12kv 13.8kv cubicle type gas insulated switchgear
KYN28A central metal-clad and metal-enclosed switchgear is produced independently based on the advanced manufacturing technique from home and abroad. It can be used to replace all sorts of old metal-enclosed switchgears.
The shell adopts the aluminum-zinc alloy coated steel sheet, processed by CNC machining tool, which ensure the high mechanical strength. The door is anti-corrosion and anti-impact coaedt. And the protection degree is IP4X
The main switch can be with the ZN63A (VSI) type of circuit breaker of this company, C3 series of fixed load switch; it is also with the interface communication.
