Product Description

 

KYN28-12(Z) Indoor HV Vacuum Switchgear

Main charateristics

1. The enclosure is made of aluminum-zinc coated sheet processed by bending several times.All operations should be done under the door closed.The hihg protection degree can avoid ingression of substance or insects enter.Wrong operation can be avoided due to its simple and effective "Five Prevention".It can equipped with ZN63A and VD4 type vacuum circuit breakers.For the truck has good interchangeability, it is easy to change vacuum circuit breakers.For saving space, the switchgear can be installed against wall and maintained from the front side.There are enough place for connection cables.Instant earthing switch can be used for eathing operation and short circuiting operation.It can be separated equipped with heater inside the VCB compartment and cable compartment to prevent condensation and erosion.It conforms to GB3906.DL404-1997 and refers to IEC-298 standard.

Applying ambient conditions
Ambient temperature: The max. temperature should below +40ºC, the min .temperature should above -15ºC.
The height above sea level should be no higher than 1000m.
The earthquake intensity should be no more than 8 degree.
Relative humidity: The average humidity of a day should be no more than 95%.The average humidity of a month should be no more than 90%.
Water vapour pressure: The average vapour pressure of a day should be more than 2.2kPa. The average vapour pressure of a month should be no more than 1.8kPa.
It should be used in the place where it is free from fire, explosion, serious fifth, chemical erosion and vibration.
