Product Description

Product Description
KYN28KYN28A-12 armored mobile metal-enclosed switchgear is suitable for 3.6-12kV three-phase AC 50Hz power grid, as the reception and distribution of electric energy, to implement circuit control, monitoring and protection. Can be used for single busbar, single busbar section system or double busbar system. The switchgear complies with IEC298 (rated voltage above 1kV and 52kV and below AC metal-enclosed switchgear and control equipment), IEC694 (common clauses for temple voltage switches and control equipment), China GB3906 (3-35KV AC metal-enclosed switchgear) and DIA04 Internal AC High Voltage Switchgear Ordering Conditions", German DIN.VDE0670 "Rated Voltage Above IkV AC Switchgear" and other standards, with perfect and reliable anti-misoperation function.

Product features 
KYN28A-12 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a new product designed and developed by our company on the basis of absorbing advanced manufacturing technology at home and abroad, which can replace the old KYN1-12, JYN2-12 and other series of products. Its products have the following obvious advantages:
1:The shell of the product is completely assembled with bolts, with high mechanical strength, which effectively ensures the neatness and beauty of the product. The cabinet door is spray-coated with strong impact resistance and corrosion resistance. The product has an IP4X level of protection for the shell. (It can be changed to iron plate according to customer needs).
2:The switch of the product can be matched with ABB VD4 vacuum circuit breaker, C3 series fixed load switch, 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.
3:No matter what kind of circuit breaker is selected, the distance of bare conductive air insulation can be guaranteed to be greater than 125mm, and the distance of composite insulation is greater than 60mm. The circuit breaker has the unique advantages of long service life, low maintenance and small size



Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
