Product Description

Introducing LIYOND 12kV Co-Boxed SF6 Gas Insulated Switchgear by Yueqing Liyond Electric Co., Ltd. Ideal for high voltage electrical power supply needs.

LY-12 Gas Insulated Switchgear

LY-12 Gas Insulated Switchgear

The LY-12 gas insulated switchgear series is a compact metal-sealed system designed for 10KV power distribution. It offers unique flexibility with expandability for full and semi-modular combinations.

The stainless steel gas chamber is filled with SF6 gas, ensuring complete sealing of all live parts and switches from the external environment. This structure guarantees reliability, safety, and maintenance-free operation.

Basic Module Schemes:
