HV Silicone Rubber Bushing
Shenyang Deguang Electric Technology Co., Ltd. specializes in the research, development, manufacturing, and sales of transformer accessories. As one of the company’s core products, the silicone rubber bushing is widely used for insulated lead-out and external connections in power transformers, prefabricated substations, and various high-voltage electrical equipment
1.The bushing is manufactured using a premium silicone rubber sheds integral injection molding process, offering outstanding resistance to pollution flashover, aging, and weathering, making it suitable for harsh operating environments such as coastal areas with high salt fog, high humidity, and heavy pollution. This significantly reduces the risk of flashover failure while extending service life and lowering maintenance costs. The internal core is cast with epoxy resin, providing high mechanical strength and stable electrical performance. The reliable sealing structure effectively prevents moisture and water ingress, ensuring long-term safe operation of the equipment.
2.The product range covers current ratings from 315A to 630A, with multiple models available in different heights and creepage distances, allowing customers to select the appropriate model based on installation space, insulation coordination requirements, and environmental conditions. All products undergo power frequency withstand voltage testing, lightning impulse testing, and partial discharge testing prior to shipment, ensuring compliance with national and international technical standards.
3.Technical Parameters:
Rated voltage: 40.5kV
Power frequency withstand voltage: 95kV/1min
Lightning impulse withstand voltage: 200kV
Partial discharge: Um≤10pC
4.Outline dimensions, mounting flange specifications, and creepage distance can be customized according to customer technical requirements. Inquiries from domestic and international customers are warmly welcomed.
