KYN61-36KV

brief introduction

KYN61-36 air-insulated metal-clad withdrawable switchgear (hereinafter as switchgear is a kind of MV switchgea r. It is designed as a withdrawable module type panel, and the withdrawable part is fitted with VD4-36E,VD4-36 withdrawable vacuum circuit breaker manufactured by Rockwill Electric 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 and monitoring of the circuit.
To prevent the condensation phenomena, a heater is necessary for switchgear and needs to be put into service when the switchgear is in readiness and service conditions. The heat dissipation problem of switchgear can be solved by the installation of ventilation facilities.
