YB Pre-positioned box type electric substation

YB Pre-positioned box type electric substation is a compact substation which combines high voltage switch system, low voltage distribution panel, distribution transformer, electric energy calculation part and power compensation device. The substation is divided into three main units – high voltage unit, transformer unit, low voltage unit. Each unit contains temperature control system, lighting system and display system. The equipment and the box both achieve IP33 protection

Product Description

Parameters

YB Pre-positioned box type electric substation

Normal installation conditions.

1. Ambient air temperature: -30°C ~ +40°C;

2. Relative humidity ≤ 95% (+25℃)

3. Altitude ≤1000m;

4. Wind speed ≤ 35m/s;

5. Horizontal acceleration ≤ 0.4m/s2, Vertical acceleration ≤ 0.2m/s2;

6. Installation places should without conductive dust, corrosive nor explosion gas. No violent vibration, vertical gradient <3º. If the switchgear will be used in conditions that exceed the normal environmental conditions, please consult with us.

Application

YB Pre-positioned box type electric substation is new type of complete equipment for electric substation and distribution, It can be used as heavy load center and can replace the traditional substation room. It is very compact and portable, easy for installation and maintains. It’s specially used as temporary power supply, such as for high buildings, residential district, streetlight, large construction sites, gymnasium, Petrochemical plant, airport, hotel, business center, etc.
