KYN28-12 series of metal clad midship closed switchgear

KYN28-12 armoured Center-metal-enclosed switching equipment (hereinafter referred to Switchgear) is the factory in attracting domestic and foreign advanced manufacturing technology on the basis of their own design and development of new products, could replace all the old type of metal-enclosed switching equipment, such as KYN1-10, JYN2-10, GBC-10 and other products. Obviously their products have the following advantages:
a, product review by the shell is aluminum zinc plate by bending CNC machining multiple forming later bolt assembly from, with very high mechanical strength, an effective guarantee for the products and tidy and beautiful, OEM Switchgear Kits & used spray coating , Has strong resistance to impact and corrosion resistance. Shell-class products with a level of security IP4X.
b, the main switch products can be configured ABB company's VD4 vacuum circuit breakers, C3 Series Switches fixed, but also can be configured a variety of domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28), to replace similar foreign Products.
Whether the selection of circuit breakers, their bare lead insulation from the air can ensure greater than 125 mm, composite insulation greater than 60 mm. Its circuit breakers are all long-life, high-parameter, less maintenance, the unique advantages of small size.
c, KYN28-12 armoured Center-metal-enclosed switching equipment for 3.6 ~ 12 KV three-phase power grid 50 HZ, as the acceptance and distribution of electric energy, and circuit control, monitoring and protection purposes. Can be used for single-bus, single-or dual-bus system sub-bus system. Switching equipment with IEC298 "rated voltage 1 KV above 52 KV and below, switching equipment and metal-enclosed control equipment", IEC694 "high-voltage switches and control equipment sharing provisions", China's GB3906 "3-36KV Metal Exchange closed switching equipment" and DL404 "Indoor exchange High-voltage Switch Cabinet Order conditions ", Germany DIN.VDE0670" rated voltage of more than 1 KV exchange switching equipment "and other standards. And a sound and reliable anti-misoperation function.

Frame

Switching equipment by G B3906-91 in the armoured equipment and metal-enclosed switch design. Switchgear structure see Figure 1: switchgear from the OEM Switchgear Kits & fixed and can take part (hand cars) the two major components, OEM Switchgear Kits & shell and the functional units of the partition are connected by bolts.

Switchgear shell grading is IP4X, circuit breakers open the room door at the level of security for IP2X. Switchgear even for a vacuum circuit breaker-hand car, even for a fixed Switches. With elevated import (export) lines, cables and other features Chuxian programme. Switchboard may be installed to counter with a double, that is, installed back-to-back or face-to-face with double.

Order Notice

Switchgear orders should provide the following technical information:
