armored removable AC metal-enclosed switchgear KYN28 (A) -12KV
High Voltage Switch Cabinet KYN28 (A) -12
KYN28-12 (Z) (GZS1) type Kai out of the exchange of metal-enclosed switchgear rated voltage 3.6.12kV three-phase AC 50Hz indoor complete power distribution unit. Its shell is completely by the complex aluminum-zinc steel sheet processed by the machine after multiple bending forming bolts, its high book L-strength, effectively guarantee the production conditions: neat and beautiful, the door with spray Coating, with a strong impact resistance and corrosion resistance. The product enclosure is IP4X rated. The main switch can be configured ABB VD4 vacuum circuit breakers, C3 series of fixed load switch. (Such as VS1, VH1, VK, ZN28), to replace foreign similar products, the entire cabinet by the instrument room, bus room, handcart room and cable components. Wood switchgear to meet the GB3906, DL404, IEC-298 and other standards, and has to prevent misuse of circuit breakers, anti-load than the push-pull car to prevent the closing of live-off switch.
