Detailed information

Summary
KYN28A-12 armored mid mounted AC metal enclosed switchgear (hereinafter referred to as the switchgear) is a new product designed and developed by our company on the basis of absorbing advanced manufacturing technology at home and abroad Products. It can replace all kinds of old metal enclosed switchgear, such as KYN1-12, JYN2-12 and other series products.
Its products have the following obvious advantages:
1.1 the shell of the product is completely assembled with bolts after the aluminum-clad zinc copper plate is processed by CNC machine tool, which has high mechanical strength and effectively ensures the integrity of the product Neat and beautiful, the cabinet door is coated with spray plastic, with strong impact resistance and corrosion resistance. The product shell has the protection level of IP4X. (it can be changed to iron plate according to the needs of customers).
1.2 the main switch of this product can be equipped with VD4 type vacuum circuit breaker and C3 series fixed load switch produced by ABB company, as well as a variety of domestic series vacuum circuit breakers (such as VS1 VHL, VK, ZN28) to replace similar foreign products.
1.3 no matter what kind of circuit breaker is selected, the air insulation distance of the bare conductor shall be greater than 125mm, and the composite insulation shall be greater than 60mm. The circuit breakers have long life, high parameters and few Maintenance, small size unique advantages.
KYN28A-12 armored mid mounted metal enclosed switchgear is suitable for 3.6-12kv three-phase AC 50Hz power grid, as the receiving and distribution of electric energy, and to control, monitor and protect the circuit Use. It can be used in single bus, single bus section system or double bus system. The switchgear shall conform to IEC298 "AC metal enclosed switchgear and control equipment with rated voltage above 1 kV and below 52kv" Standby, IEC694 "common terms for high voltage switchgear and control equipment", GB3906 "3-36kv AC metal enclosed switchgear" and DIA04 "ordering conditions for indoor AC high voltage switchgear", Germany DlN.VDE0670 Requirements of AC switchgear with rated voltage above 1 kV and other standards. It has perfect and reliable anti misoperation function.
