Product Description

Armored Removable AC Metal-enclosed Switchgear

The KYN series air-insulated metal-enclosed withdrawable switchgear is a modular power distribution unit designed for medium/high-voltage electrical systems with withdrawable panel. The withdrawable unit can be fitted with the vacuum circuit breaker. It can also accommodate an isolation truck, PT truck, fuse truck, and other optional modules. Its core features include a fully enclosed metal-clad structure and removable functional modules (e.g., circuit breaker carriages).

Air-Insulated High Voltage Electrical Compact Substation Switchgear

The indoor high-voltage vacuum circuit breaker

It can quickly cut off fault currents to protect the power system. It has advantages like high breaking capacity, long service life, low maintenance, good arc-extinguishing performance, and reliable operation in indoor power distribution systems.

The vacuum circuit breaker handcart

It controls the power flow by making and breaking normal load currents, and protects the electrical system from faults by quickly interrupting short-circuit currents. Its advantages are remarkable, featuring high reliability thanks to vacuum arc-extinguishing technology, a long service life due to minimal wear, and ease of maintenance as it can be easily removed for inspection and repair.
