10kV State Grid Replacement-type Prefabricated Non-metallic Type Substation

key product feature

1.Compact and efficient structure: The substation has a compact design and a small footprint. The heat sinks are placed externally, resulting in better heat dissipation.

2.Advanced and reliable technology: Utilizing a new series of transformer technology, the structure is reasonable and safe and reliable.

3.Optimized insulation design: Using transformer oil as the insulation medium for the high-voltage components on the 10kV or 35kV side, it significantly reduces the safety distance.

4.Fully enclosed and stable durable: The oil tank adopts a fully enclosed structure, isolating from the atmosphere, reducing the impact of oxidation and moisture, and enhancing the stability and safety of the system; paired with a plate-type heat sink, it is convenient for disassembly and maintenance.

5.Strong environmental adaptability: The box body is treated with special shot blasting technology, possessing excellent anti-corrosion and anti-sun exposure properties, effectively resisting wind and sand erosion.

6.Complete low-voltage protection: The low-voltage side uses the latest domestic intelligent circuit breakers and plastic shell air switches, with high breaking capacity and excellent protection performance.

7.Intelligent remote monitoring: The transformer oil tank can be equipped with pressure gauges and thermometers with communication interfaces, and the load switch can be equipped with travel switches to achieve remote monitoring, operation and maintenance of the transformer.

8.High protection level: The box body is fully sealed, with the protection levels of the high and low voltage chambers reaching IP54, and the protection level of the transformer body reaching IP68.
