High Voltage Electrical Switchgear
Product Overview
High voltage electrical switchgear is a core control and protection solution used in power systems operating at voltage levels of 3.6kV and above. The product range includes mainstream categories such as metal-enclosed switchgear, gas insulated switchgear (GIS), and prefabricated substations. These systems provide comprehensive functions including circuit switching, overload protection, fault isolation, and system regulation.
The high voltage electrical switchgear series is manufactured in strict accordance with GB/T and DL/T national and industry standards. The cabinet structure adopts aluminum-zinc coated steel plates and powder-coated cold-rolled steel materials, delivering strong structural stability and excellent insulation performance. An advanced interlocking protection system is built in to ensure safe and reliable operation.
Core Product Features
- Complete voltage level coverage suitable for medium-voltage, high-voltage, and ultra-high-voltage grid applications;
- Integrated system design enables complete power distribution and protection functions without additional supporting equipment;
- Excellent protective performance with resistance to electric arc damage and environmental aging, suitable for long-term indoor and outdoor use;
