Factory KYN28 Power Distribution Panel Board MV 12KV 24KV, 36KV High Voltage Air Insulated Switchgear
■ Overview
The switchgear with high breaking capacity and low values of intercepting VS1,VMK vacuum breaker or VD4 vacuum circuit breaker,reliably prevent
wrong operation function,prevent load push,prevent the shake
handshandle together when grounding switch is closed circuit breaker, prevent charged,wrongly grounding switch,prevent charged into every "five" interlock function,is a kind of superior performance of the power distribution device.
■ Using environment
·Ambient air temperature≤+40℃ and ≥-15℃
·Equipment installation place of the sorting the sea level:1000m
Ambient humidity daily average relative humidity≤95%Monthly average relative humidity≤90%
·The earthquake intensity is less than 8 degrees
·Surrounding air should not be corrosive or flammable gas,water vapor and other obvious pollution.
·No serious contamination and frequent violent vibration.
■ Product features
The design and manufacture of the switch cabinet and the components adopted are in conformity with the international electrotechnical
commission (IEC)standards and national (GB)standards,taking full account of the customer's requirements for simplicity,reliability,safety and other aspects:
·Clear and easy to follow instructions
·All operations are done on the front
·Parameters of intelligent controller are set on site
·Only simple routine inspection and cleaning and maintenance are required,and lubrication is required every five years
·New and reliable 3d parametric design is a powerful guarantee of reliability
·The quality assurance system meets the requirements of IS09001
·Complete air insulation,no risk of leakage
·Separate functional compartments and pressure release channels
·Up to IP4X level of protection
