XG-12 box type fixed metal enclosed switchgear

I want to make an inquiry
Product Description
XGN2-12 box type fixed metal-enclosed switchgear (referred to as switchgear) is designed according to national standard GB3906, conforms to the International Electrotechnical Commission IEC298 standard, and has "five-proof" blocking function. This product is suitable for three-phase AC 50Hz rated voltage 3.6-12kV, rated current 630-3150A three-phase AC single bus, single bus with bypass system, as a means of receiving and distributing electrical energy. It can meet the requirements of various types of power plants, substations and industrial and mining enterprises.
◆The switchgear is a metal-enclosed box structure. The cabinet is divided into a circuit breaker room, a busbar room, a cable room, and a relay room. The chamber is separated from the chamber by a steel plate.
◆ The circuit breaker room is in the lower part of the cabinet and has a pressure release channel. The busbar compartment is in the upper rear part of the cabinet, and the busbars are arranged in a shape. The cable compartment is located behind the lower part of the cabinet, and the indoor insulator can be provided with a monitoring device. The relay chamber is in front of the upper part of the cabinet. There is a relay mounting plate in the room, instructions and signal components can be installed on the door, and a secondary small busbar can be arranged on the top.
◆The switchgear is double-sided repaired, and the lights are installed in the circuit breaker room and the cable room. Below the front door, there is a grounded copper busbar parallel to the width of the cabinet.
