Box-type Mobile Transformer Substation

Description

Box-type mobile substation is a compact complete power distribution device that combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. This box-type substation is suitable for 12kV three-phase AC system with a rated frequency of 50Hz. It is used in residential quarters, commercial hotels, large construction sites, high-rise buildings, industrial and mining enterprises and other places with a capacity configuration of 2500kVA and below.

Conditions of Use:

Altitude:≤1000m

Wind speed: ≤34m/s (not more than 700Pa)

Ambient temperature: maximum temperature +40℃, minimum temperature -35℃;

Relative humidity: the daily average is not more than 95%, the monthly average is not more than 95%

Anti-vibration: horizontal acceleration not more than 0.4m/s2, vertical acceleration 0.15m/s2

Installation site inclination: no more than 3°

Install in a place free from fire, explosion hazard, heavy pollution, chemical corrosion and severe vibration.

If the above conditions are exceeded, you can negotiate with the company.
