Description

KYN61-40.5 Indoor Metal Clad Switchgear

The main feature of KYN61-40.5 metal-enclosed switchgear is that the cabinet is equipped with a new type of fully insulated vacuum circuit breaker and a spring-operated power mechanism. The cabinet body is assembled by galvanized steel plate, which improves the matching accuracy between the handcart and the cabinet body. The handcart is very portable and highly interchangeable.

This switchgear is used in 35kV three-phase AC 50Hz power system. It is used in the power distribution room of power plants, substations and industrial and mining enterprises to receive and distribute electric energy, and has the functions of control, protection and monitoring.
