  General of 12kv switchgear

   

            KYN18A-12 AC indoor withdrawout 12kv switchgear is the central vacuum switch cabinet which mainly applies the ZN12-12 vacuum circuit breaker, but also can be equipped with ZN22B-12 vacuum circuit breaker and 3AF, 3AH vacuum circuit breaker of Siemens.

        12kv switchgear complies with the standard of GB3906-91 (3-35KV AC metal-enclose switch cabinet), the standard of DL4047-91 (indoor AC switch cabinet ordering technique) and the standard of IEC298 (AC metal-enclosed and control equipments).  12kv switchgear is used in the AC 3-10 KV three-phase 50 Hz single bus power system to receive and distribute the power. It is widely used in various kinds of power plants, substation and industrial and mining enterprises.  12kv switchgear can be installed against the wall (not recommended) and non-against the wall installed
