Product Description
General
KYN61-40.5 air-insulated metal-clad drawout type switchgear is a kind of MV switchgear. It is designed as drawout type module type panel, and the drawout type part is fitted with VD4-36E, VD4-40.5 drawout type vacuum circuit breaker manufactured by Cooper Nature company. It can also be fitted with isolation truck, PT truck, fuses truck and so on. It is applicable to three phase AC 50/60 Hz power system, and mainly used for the transmission and distribution of electrical power and control, protection, monitoring of the circuit.
