Product Desciption

Kyn61 40.5KV Mv Power Distribution Switchboard

General

KYN61-40.5( same as unigear Z3.2) air-insulated metal-clad withdrawable switchgear( hereinafter as "switchgear") 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.
