EGC/GT-12/C 630 indoor 12kV high voltage Solid State switchgear

          SWITCHGEAR is divided into high voltage and low voltage. High-voltage Ring Network Cabinet, central cabinet, GG1A and so on. There are also many types of ring-net cabinets. Ring Network Cabinet, the so-called "Ring Network Cabinet" is each distribution branch with a switchboard (outlet switchboard) , this switchboard bus is also a part of the ring trunk line. That is to say, the Ring Trunk Line is made up of the bus bar of each outlet cabinet. Each out-of-line cabinet is called "Ring Network Cabinet" . In fact, a separate ring out of the cabinet is not to see the "ring network" meaning. These ring network cabinet are not big, so the ring network cabinet high voltage switch generally does not use the circuit breaker with complex structure to take the high voltage load switch with high voltage fuse. That is to say, the high-voltage switch in the ring network cabinet is generally load switch. The Ring Network Cabinet replaces the circuit breaker with a combination of a load switch to operate the normal current and a fuse to cut off the short-circuit current. Of course, this can only be limited to a certain volume. Such switchgear can also be used in distribution systems with non-ring network structure. Therefore, with the wide application of such switchgear, "Ring Network Cabinet" out of the ring network distribution category and generally refers to the load switch as the main switch of the high-voltage switchgear.
