Product Desciption
1.General description
ZN63(VS1)1-12 indoor M.V. is an indoor switchgear with tri-phase AC 50Hz,rated voltage of 12kV,control and protection for industrial and mining enterprises,power plants and substations,electrical facilities and for frequent operation place adopting VET operating mechanism and circuit breaker integrated design can be used as a fixed installation unit can also be equipped with special advance mechanism,the composition of handcart unit used some of the main circuit can use the whole solid seal post with high reliability,maintenance free,in order to achieve smaller circuit breaker,can be equipped with KYN2BA 12(GZS) and other handcart switch cabinet.In the home it can also be used with fixed XGN switchgear.
ZN63 is regular type mechanism,ZN83 is improved on the basis of ZN63.All ZN83 mechanisms can be replaced by ZN63 mechanisms,they are universal mechanism.
2.Main technical parameter
(1)It is forced cold air when rated current is 4000A
