XGW-12 type Box Switching Station

Description:

With the continuous development, the switching station in the integrated and modular way has emerged. XGW-12 type Intelligent Box Switching Station integrates the detection, protection, control and measurement of power equipment under normal and accident conditions with the use of modern sensor technology, communication technology, computer network technology, greatly improving the operational reliability of urban power grids.

Features:

u Less floor space and shorter construction period.

u Integration of primary and secondary systems as well as modularized assembly. 

u Multiple options and flexible configuration.

u Perfect Five-protection and Interlocking system. Safe and reliable, easy to repair.

Using environment:

u Temperature: Min -40℃~Max+40℃;

u Relative humidity: Daily average ≦95%; Monthly average≦90%;
