Indoor AC Metal Armored Switchgear

KYN28A-12 AC metal armed switchgear is widely used in 6kV/6.3kv/7.2kv/10kv/12kv/22kv/24kv/33kv/35kv/40.5kv box transformers, distribution cabinets, urban power grid transformation, residential quarters, high-rise buildings, industries and mines, hotels, shopping malls, airports, railways, oil fields, wharfs, high-speed roads, temporary power equipment and other indoor and outdoor places.

The switchgear has the following advantages:

1. The shell of the product is completely assembled by bolts, with high mechanical strength, which effectively ensures the neatness and beauty of the product. The cabinet door is spray-coated, which has strong impact resistance and corrosion resistance. The product shell has an IP4X level of protection. (It can be changed to iron plate according to customer needs).

2. The switch of this product can be equipped with VD4 type vacuum circuit breaker, C3 series fixed load switch produced by ABB company, and can also be equipped with a variety of domestic series vacuum circuit breakers (such as VSIVHI, VK, ZN28).

3. No matter which circuit breaker is selected, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation can be greater than 60mm. The circuit breakers have the unique advantages of long life, low maintenance and small size
