KYN28-12
NEW ARMORED REMOVABLE AC METAL-
ENCLOSED SWITCHGEAR YINGMING POWER
Structural features

The structure of the switchgear is shown in the figure below. All-metal modular assembly structure, the cabinet is made of imported aluminum-zinc
plate with strong anti-corrosion ability, no surface treatment, CNC high-precision equipment processing, advanced multi-folding technology, connecting
rivet nut, high strength Bolted, high precision, light weight and good strength.
Switching equipment can be equipped with vacuum circuit breakers such as VS1 series, VD4 series and ZN65 series produced by our company. It has
wide adaptability and strong interchangeability. The handcart has a working position, a test position, and a positioning and display device at each
position, which is safe and reliable.
The cable room can hold up to 9 single-core cables. The equipment has reliable mechanical and electrical interlocking devices, which fully meet the
requirements of “five-proof”. Each room is equipped with a pressure relief passage to ensure personal safety.
