KYN28-12 in the home-type armored AC metal-enclosed switchgear

Oroduct Overview

ZHE JIANG BOGUANG ELECTRICAL TECHNOLOGY CO.,LTD. has been committed to product quality control and enterprise management "manufacturing high-quality goods, integrity service" is always our commitment to the customer. The company produces crystal sales of customers is the main power supply bureau, the company (hereafter called sacsc), mechanical and electrical equipment company, best-selling domestic provinces and cities autonomous regions, many times by the national key factory, export Europe and Africa southeast Asia etc, in use process to get the user high praise!

Product Overview and Scope

KYN28A-12 armored mounted AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a gas supply company on the basis of absorbing advanced manufacturing technology, based on its own design and development of new products that can replace all the old type of metal-enclosed switchgear such KYN1-12, JYN2-12 other products. The product has the following distinct advantages:

◆ product's enclosure is completely bolt assembled with high mechanical strength, effectively ensure the orderly and beautiful products, doors using spray coating, has a strong impact

And corrosion resistance. Product housing has IP4X level of protection. (Can be changed according to customer needs iron).

◆ The product can be equipped with ABB switch production company VD4 vacuum circuit breaker, C3 series of fixed load switch, but also can be configured to a variety of domestic series vacuum circuit breaker (eg VSIVHI, VK, ZN28), to replace similar foreign products.

◆ Whether it is the selection of the circuit breaker, which bare conductor can ensure air insulation distance is greater than 125mm, composite insulation is greater than 60mm. The unique advantages of its circuit breakers have a long life, low maintenance, small size

KYN28A-12 armored mounted metal-enclosed switchgear is suitable for three-phase AC 50Hz grid 3.6-12kV as receiving and distributing power, and circuit implementation of control, monitoring and protection purposes. Can be used for single-bus, single busbar system or dual-bus system. Switching equipment meets IEC298 "rated voltages above 1kV and below 52kV AC metal-enclosed switchgear and control equipment", IEC694 "Temple-voltage switchgear and control equipment sharing clause" of GB3906 (3-35kV AC metal-enclosed switchgear "and DIA04" households High Voltage Switchgear order condition in the exchange, "the German DIN.VDE0670" IkV above the rated voltage AC switch equipment "and other standards. and has a complete and reliable function to prevent misuse.
