82 Pins 4000A Clubes Copper Contact with Silver Plate for Vacuum Circuit Breaker

          The cabinet is large but easier to maintain. Medium case is large, but maintenance is more convenient. Ring case is small, but maintenance is not convenient.( SM6 now has a high voltage loop switch cabinet with special SFset circuit breaker. SGN1A-12(Z) small fixed separator, developed jointly, can achieve the basic function of medium case using ABB LEG(Z1)-12 circuit breaker, but the ring net case or small fixed compartment can be set up as a low voltage circuit breaker. Only according to the fixed mode of installation, so that when the circuit breaker failure, need to be replaced immediately, not only need to cut off the upper power supply, but also trouble to replace. It is convenient to replace the handcar switch.

            So the ring net cabinet is not only used as the contact switch cabinet, but also as the loop in and out of the switch cabinet, measuring cabinet, PT cabinet. Loop-in and loop-out switchgear not only can load switch-fuse combination, but also can load circuit breaker, such as domestic HXGN, Schneider SF6,  8DH, and second protection can install microcomputer protection device. But the ring net cabinet breaker has the load limit, each factory's ring net cabinet limits are different. If  RM6 ring net cabinet, Transformer high voltage switch protection is greater than 2000 KVA capacity, must adopt circuit breaker + VIP 300 microcomputer protection. However, the load of the in-and-out line of the cabinet is not limited(except the larger load is 1 meter wide).
