Summary
All live parts and switches of SGW-12 are sealed in SF6 gas box. The gas box is made of 3mm thick stainless steel plate, and there is a reliable pressure relief channel at the bottom of the cabinet, which can protect the personal safety of gas operators to the maximum extent.
The air box and the air box are connected by insulated bus, which is safe and convenient, and the insulated bus and the air box are isolated from each other. In case of fault, it can effectively prevent the spread of the accident.

Modular design
SGW-12 adopts the modular design scheme, and its basic modules are load switch module, combined electrical module and other special function modules. Any combination of these modules forms a common box structure. In the combination module, any function is roughly the same as the internal structure of the basic module.

Normal use conditions
SGW-12 is suitable for high and low temperature (+ 40 ℃ ~ - 40 ℃), humid, dusty, salt polluted, mining, high altitude (1000m) and other environments. The short-time immersion within 24 hours will not affect the use.
Note: if the altitude is higher, please indicate the specific altitude.

Product meets the standard
1. international standard，IEC60056、IEC60298、IEC60129、IEC60420、IEC60265、IEC60694 ...。
2. international standard：GB3804、GB3906、GB11022 ...。

Flexible outgoing and expansion mode
All modules of SGW-12 can realize the connection mode of side outgoing line and side expansion or outgoing line and top expansion according to the user's requirements, meeting the needs of power supply scheme to the maximum extent.
