Model explanantion
Feature of Removable AC Metal Clad Switchgear
- The busbar adopts heat-shrinkable insulating material or epoxy-coated insulating means to optimize the electrode shape so that the cabinet structure is compact and the floor space is reduced.
- The cabinet is made of high-quality cold-rolled steel plates and imported aluminum-zinc coated plates, which are formed by CNC sheet metal processing and are connected by high-strength bolts, nuts, and rivet nuts.
- Insulation boards are installed in the busbar room, handcart room, and cable room in the cabinet, and the insulation level is greatly improved.
- Can be configured with domestic VS1-24 vacuum circuit breaker or Schneider’s VH4 or Alstom FP series sulfur hexafluoride circuit breaker to meet the needs of different users.
- The combined valve can be opened flexibly. As the circuit breaker is pulled out, the valve will be automatically closed and forced to lock, preventing the danger of accidentally touching high voltage.
- The friendly man-machine interface makes the operation of the switch cabinet programmatic and formulaic, and the operator can see it at a glance.
- The main wiring scheme can reach more than 160 kinds, and the structure has strong adaptability, which can meet the needs of different users
