Description

KYN61-40.5( same as unigear Z3.2) air-insulated metal-clad withdrawable switchgear( hereinafter as "swit chgear") is a kind of MV switchgear.

It is designed as withdrawable module type panel, and the withdrawable part is fitted with VD4-36E, VD4-40.5 withdrawable 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.
