KYN28-12 high voltage switch cabinet

Product overview

KYN28-12 armored mid-mounted metal-enclosed switchgear is suitable for 3.6 ~ 12kV three-phase AC 50Hz power grid for receiving and distributing electric energy, and for controlling, monitoring and protecting the circuit. Can be used for single bus, single bus section system or double bus system. Switchgear complies with IEC298 "AC Metal-sealed Switchgear and Control Equipment with Rated Voltage Above 1kV and Below 52kV", IEC694 "Common Terms for High Voltage Switchgear and Control Equipment", China's GB3906 "3-35kV AC Metal-sealed Switchgear" and DL404 "Ordering Conditions for Indoor AC High Voltage Switchgear". And has a perfect, reliable anti-misoperation function.

Product Features

KYN28-12 armored mid-mounted metal-enclosed switchgear (hereinafter referred to as switchgear) can replace all kinds of old metal-enclosed switchgear, such as KYN1-10, JYN2-10, GBC-10 and other products. Its products have the following obvious advantages:

■ The shell of the product is completely made of aluminum-zinc-coated steel plate processed by CNC machine tools and then assembled with bolts after multiple bending and forming. It has high mechanical strength and effectively ensures the neatness and beauty of the product. The cabinet door is coated with plastic spray. It has strong impact resistance and corrosion resistance. The product enclosure has an IP4X class of protection.

■ The main switch of this product can be equipped with imported vacuum circuit breakers, and can also be equipped with a variety of domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace similar foreign products.

■ No matter what kind of circuit breaker is selected, the air insulation distance of its bare conductor 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, less maintenance and small size.
