The KYN series air-insulated metal-enclosed withdrawable switchgear is a modular power distribution unit designed for medium/high-voltage electrical systems with withdrawable panels. The withdrawable unit can be fitted with a vacuum circuit breaker, isolation truck, PT truck, fuse truck, and other optional modules. Its core features include a fully enclosed metal-clad structure and removable functional modules.
Indoor High-Voltage Vacuum Circuit Breaker
It can quickly cut off fault currents to protect the power system, offering high breaking capacity and long service life.
Vacuum Circuit Breaker Handcart
Controls power flow and protects systems by interrupting short-circuit currents with high reliability and ease of maintenance.
