Model and its meaning
Using heat-shrinkable insulation materials and epoxy coating insulation technology to optimize the electrode shape, the cabinet has a compact structure.
The switch cabinet body is made of cold-rolled steel plate, which is formed by CNC sheet metal processing, and then connected by high-strength bolts and nuts and rivet nuts. The surface of the components is sprayed or galvanized.
series of sulfur hexafluoride circuit breakers to meet the requirements of different users.
The functional compartments of the switchgear are separated by metal partitions and are equipped with independent pressure release channels.
The circuit breaker, grounding switch and other operations can be performed when the cabinet door is closed, and the door can be closed.
The mechanical interlocking device "five prevention” between the handcart, the circuit breaker, the grounding switch and the rear cabinet door to prevent misoperation is complete, safe and reliable.
