Product Description

Product discription
 1.About KYN28A-12:
KYN28A central metal-clad and metal-enclosed switchgear is produced independently based on the advanced manufacturing technique from home and abroad. It can be used to replace all sorts of old metal-enclosed switchgears.
The shell adopts the aluminum-zinc alloy coated steel sheet, processed by CNC machining tool, which ensure the high mechanical strength. The door is anti-corrosion and anti-impact coaedt. And the protection degree is IP4X
The main switch can be with the ZN63A (VSI) type of circuit breaker of this company, C3 series of fixed load switch; it is also with the interface communication.
The insulation distance is over 125mm, composite insulation is over 60mm. all the circuit breakers have the features of long working life, high parameters, less maintenance, small size and so on

2.Working conditions:
The type of transformers are applicable to 35KV and below, the small unattended substation, with main interior capacity of 5000KVA and below, is widely used in urban industrial substation, 10KV switch stations, ring network system, rural power grid 35KV substation and other occasions.

3.Service Condition
a. Ambient Temperature:      Max. +40°C     Min. -15°C
b. Ambient Humidity:     Daily average relative humidity:≤95%      Monthly average relative humidity:≤90%
c. Max. altitude:1000m
d. The degree of condensation and pollution  IPII
In case of the switchgear used in the conditions beyond the above limit, the customers shall consult with the manufacturer.
