KYN10-40.5 armored removable AC metal enclosed switchgear
Kyn10-40.5 AC metal enclosed switchgear (hereinafter referred to as switchgear) is an indoor complete set of three-phase AC 50 Hz single bus system, which is used to receive and distribute 35 kV network power.
Product features
The switch cabinet belongs to armored structure. The cabinet has two forms of welding and assembling, which are composed of cabinet and handcart. The welding type cabinet body is made of section steel and steel plate by bending and welding; the assembled type cabinet body is made of imported aluminum zinc coated steel plate by punching, shearing, bending and forming with CNC equipment, and then assembled with high-strength bolts. The product has the advantages of small volume, large breaking current, convenient installation, operation and maintenance, safe and reliable use, and is a new generation of switchgear in China.
