YB-12/0.4(F.R)Outdoor prefabricated substation (European style)
Features
1.The trinity of high-voltage switchgear, transformer and low-voltage switchgear has a strong complete set
2.The high and low voltage protection is perfect, the operation is safe and reliable, and the maintenance is simple;
3. Small area, low investment, short production cycle and convenient movement;
4. The wiring scheme is flexible and diverse;
5. Unique structure: the unique honeycomb structure double-layer (composite board) shell is firm, heat-insulating, heat-dissipating and ventilating, beautiful, and high-level of protection. The shell materials are stainless steel alloy, aluminum alloy, cold-rolled plate, and color steel plate.
6. Variety of styles: general, villa, compact and other styles;
7. The high-voltage ring network cabinet can be equipped with a network automation terminal (FTU) to realize the reliable detection of short-circuit and single-phase grounding faults. It has the "four remote" function, which is convenient for the automatic upgrade of the distribution network.
Use Environment
1. Altitude: not more than 1000m;
2. Ambient temperature: -25℃-+40℃;
3. Relative humidity: the daily average value is not more than 95%.；The monthly average value is not more than 90%;
4. Installation site: A place free from fire, explosion hazard, conductive dust, chemically corrosive gas and severe vibration. If the above conditions are exceeded, the user can consult with our company.
