KYN28- 12 AC METAL- CLAD WITHDRAWABLE ENCLOSED SWITCHGEAR CABINET
Kyn28 high voltage switchgear is used for power generation, transmission, distribution, power conversion and consumption of power system, which plays the role of on-off, control or protection. The voltage level is 12kV electrical products, mainly including high voltage circuit breaker, grounding switch, transformer, etc. Kyn28 cabinet body is composed of cabinet frame and withdrawable handcart. All kinds of handcart are pushed and withdrawn by worm shaking, and its operation is light and flexible. The whole handcart is small in volume and convenient for inspection and maintenance. The handcart has a set of devices in the test position and working position in the cabinet to ensure the reliability of mechanical interlocking. According to the different uses of handcart, it can be divided into: transfer car, Pt car, fuse car, metering vehicle, isolation vehicle, lower Pt car, lower lightning arrester car and grounding vehicle.
Features
1. Easy and effective five-safety locking device to avoid false operation.
2. Compatible with VCB VS1-12(ZN63A), VD4, ZN12, 3AH, VB2, and VEP, vacuum contactor VC7, etc.
3. Compatible with PT handcart, isolating handcart, fuse handcart etc,and handcarts of same purpose are interchangeable.
4. The cabinet can be mounted against the wall and accessible for maintenance in the front as to save space.
5. The circuit breaker compartment and cable compartment maybe respectively mounted with heater avoid condensation and Corrosion.
6. Spacious cable compartment enables access of several cables.The protection level of the enclosure is IP4X,and each compartment is IP2X.
7. Material optional with galvanized steel or Aluminum-zinc coated steel.
