Prefabricated compact substation, also known as compact substation or package substation. It is consists of high-voltage switchgear, distribution transformer and low-voltage power distribution device
Prefabricated substation, also known as compact substation or package substation. It is consists of high-voltage switchgear, distribution transformer and low-voltage power distribution device, which are prefabricated indoor and outdoor compact power distribution equipment in a factory according to a certain wiring scheme. At the same time, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat- insulating, fully enclosed, movable steel structure box, especially suitable for urban network construction and transformation. A brand new substation. Box-type substations are suitable for mines, factories, oil and gas fields and wind power stations.
Features:
1. Substation exterior wall
Place the steel bar in the mold, add glass fiber reinforced concrete (Composite ciment verre or CCV), after solidification, use Outdoor anti-rust paint for painting.
2. Substation Base
Using rigid strength channel steel and reinforced steel, through multiple anti-rust and painting processes, it is safe, firm and corrosion-resistant.
3. Metal Door Frame
Optional1: The door frame made of high-strength steel and the outer door of the substation made of glassfiber cement blocks not only ensure the strength, but also ensure the durability andcorrosion resistance.
Optional2: The door frame made of high-strength steel and the outer door of the substation made of Composite metal plate, reduce weight and increase heat dissipation.
4. Ventilation
Shutters type vent is good for Waterproof, dustproof, heat dissipation.
5. Installation Method
Install directly on the concrete foundation
