General
KYN28-12 armoured middle-mounted metal enclosed switchgear (hereinafter referred to as switchgear) is a new product with own design and development on the basis of absorbing advanced technology abroad, it can replace the old metal enclosed switchgears, such as KYN1-10, JYN2-10, GBC-10 series, etc.
The shell is bolted by Al-Zn alloy coated steel plates which are formed after multiple bending by CNC machine tool to ensure not only the high mechanical strength, but also the tidy and beautiful product. The door is plastic sprayed to ensure the high impact resistance and corrosion resistance ability. The shell has the function of IP4X level protection.
The main switch can be configured VD4-type vacuum circuit breaker, C3 series fixed load switch, meanwhile, it also can be assembled several domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace the similar products.
No matter which kind of circuit breaker is chosen, the air insulation distance should be ensured to be greater than 125mm, the composite insulation distance should be greater than 60mm. the circuit breaker have the special advantages of long life, high parameter, less maintenance and small size.
Operational Environment
a. Ambient Temperature: -10℃~+40℃
b. Relative Humidity: Daily average is not greater than 95%, monthly average is not greater than 90%
c. Elevation: Not higher than 1000m
d. The seismic intensity should not be greater than 8 magnitude
e. It should be operated in the place without danger of fire, explosion, serious dirtiness, chemical corrosion and acute shaking If it is planed to operate in the condition out of the above limits, the customers should negotiate with us to decide the allowable operational conditions and technical measures.
