630A 12kV 50Hz Cable Junction Box Cable Branch Box Fixed Structure Medium Voltage Products
Overview
XGW-12 box-type switching station (outdoor ring net box) is equipped with ZBF series box-type gas-insulated metal-enclosed switchgear. It is suitable for three-phase AC 50Hz, rated voltage 12kV power system, used for splitting and combining load current and overload current, and used for electric energy distribution, control and protection in the power system. As a ring network and terminal power supply equipment, it is widely used in the construction and transformation of urban and rural networks.
This box-type opening and closing has the characteristics of small size, compact structure, convenient combination, beautiful appearance, safe and reliable operation, convenient maintenance, and small on-site installation workload.
