High and low voltage switchgear

The solid-insulated ring network cabinet uses new solid insulating materials (such as epoxy resin, silicone rubber, etc.) instead of traditional gas insulation media.

The armored mid-mounted metal-clad switchgear is constructed with cold-rolled steel plates, formed via CNC processing and assembled into a cabinet with armored compartmentalized structure, internally divided into independent circuit breaker chamber, busbar chamber, cable chamber, and relay instrument chamber.

The unit-type AC metal ring network switchgear is a medium-voltage power distribution equipment with a modular structure, using high-quality steel as the cabinet material and adopting a unitized combination design, integrating core components such as load switches, fuses, and busbars internally.

The box-type fixed AC metal switchgear is made of high-strength steel, with a fixed structure design integrating core components such as circuit breakers, isolating switches, and busbars, without drawer-type or mid-mounted movable parts.

Gas-insulated Metal-clad Switchgear (GIS) uses a metal-enclosed housing as the carrier, filled with SF₆ gas as the insulation and arc-extinguishing medium, integrating core components such as circuit breakers, disconnectors, earthing switches, and busbars into a sealed integrated system.

The low-voltage draw-out switch cabinet is a low-voltage power distribution equipment suitable for AC 50Hz, rated voltage 380V-1000V. It adopts a modular drawer-type structure, integrating low-voltage electrical components such as circuit breakers, contactors, and relays.
