Normal service condition
●Ambient air temperature: maximum temperature+40℃, minimum
temperature-10℃;
●Altitude:≤1000m;
●Surrounding relative humidity: daily average ≤95%, monthly average
≤90%;
●Ambient air: not suitable for places with corrosion,serious
pollution, flammable gas and violent vibration;
●lf an earthquake occurs, the intensity of the earthquake cannot
exceed 8.
Main feature
●The cabinet body is made of aluminum zinc plate processed byCNC
equipment, spliced or riveted by bolts, and the structure is fully
assembled.
● lt can be equipped with ZN85-40.5 vacuum circuit breaker
handcart,VN1,VD4 or HD4 vacuum circuit breaker handcart at the same
time, and the main bus line of the switch cabinet is through
without the transition cabinet.
●Cable room space is sufficient, and the clean air distance between
phases can be ensured to be greater than 300mm, and there is no
need to install insulation partition between phases.
