KYN28-24 metal-armored shifting switch cabinet is suitable for three-phase AC 50Hz, 24kV single busbar section power system, it also control, protection and monitoring for the circuit, meet the requirements of IEC60298,GB3906,DL404 and other standards, and has perfect "five preventions" function.
KYN28-24highvoltagecabinetisfully developed and designed by our company based on years of experience in cabinet production. the cubicle body is of high accuracy,strong corrosion resistance and inoxidation.Further more it has lighter weight,highter mechanism strength and more beautiful appearance than other similar ones.the body is built up in construction and jointed with bolts and nuts so that the production cycle is shortened,the part generaliztion raised,the space area reduced and the production procedure optimized. The highest rated current of the product can reach 2500A.The products are mainly used in the developed areas of new industrial parks or export projects.
