The KYN550-12 armored, center-mounted, metal-clad switchgear (hereinafter referred to as switchgear) can replace various older types of metal-clad switchgear, such as the KYN1-10, JYN2-10, GBC-10, KYN28-12 series products.
◆ The product's enclosure is completely made of aluminum-zinc coated steel plate, which is processed by machine tools and multiple bending processes before being assembled with bolts. It has high mechanical strength, effectively ensuring the neatness and beauty of the product. The cabinet door is coated with spray plastic, which has strong impact resistance and corrosion resistance. The product enclosure has an IP4X protection level.
◆ The bare conductor air insulation distance of this product can be guaranteed to be greater than 125mm, and the composite insulation is greater than 60mm. Its circuit breakers have the unique advantages of long life, high parameters, low maintenance, and small size. The KYN550-12 armored, center-mounted, metal-clad switchgear is suitable for 3.6~12kV three-phase AC 50Hz power grids, used for receiving and distributing power, and for controlling, monitoring, and protecting circuits. It can be used for single busbar, single busbar sectionalized systems, or double busbar systems. The switchgear conforms to IEC298 "AC metal-enclosed switchgear and controlgear above 1kV and up to 52kV", IEC694 "Common clauses for high-voltage switchgear and controlgear", China's GB3906 "3-36kV AC metal-enclosed switchgear", and DL404 "Indoor AC high-voltage switchgear ordering conditions", and German DIN.VDE0670 "AC switchgear above 1kV", and other standards, and has complete and reliable anti-misoperation functions.
