Product Description
The Box-type Substation, often referred to as a prefabricated substation, is a masterful blend of high-voltage switchgear, distribution transformers, and low-voltage power distribution devices. This innovative solution is meticulously crafted into a single, factory-prefabricated unit, suitable for both indoor and outdoor settings. Leveraging an advanced wiring scheme, this compact power distribution equipment seamlessly integrates essential functions such as transformer step-down and low-voltage power distribution. Housed within a robust steel structure, it is designed to be moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, and easily movable. Our comprehensive range features European-style, American-style, and underground box-type substations, each engineered to meet diverse high-voltage application needs with unparalleled efficiency and reliability.


Product Features: 1. Maximizes land use by eliminating the need for land acquisition and extensive civil construction, significantly reducing infrastructure costs. 2. No ground-level obstructions, preserving the environment and maintaining scenic views. 3. Fully buried installations on lawns and green belts allow for decorative elements on the surface, such as sculptures or rockeries. If unobstructed ground is needed (including ventilation ducts), opt for the square type prefabricated substation. 4. The power distribution equipment is securely set underground, ensuring safety and reliability. 5. Ground-level areas remain unaffected by transformer noise. 6. The cooler and shadier underground environment ensures a stable temperature rise during transformer operation. 7. A spacious internal area of the fully buried prefabricated substation allows for maintenance activities without disrupting the surface or surrounding environment. Transformer: S series of oil-immersed transformer. Product Standards: 1. GB10941.2-1996 'Power Transformer' 2. GB109435-2003 'Power Transformer' 3.
