HV (DIN) German standard transformer bushing

Shenyang Deguang Electric has been deeply involved in the production of transformer insulation components for many years, integrating research and development, manufacturing, and sales. We specialize in supplying 12kV, 24kV, and 36kV German standard high voltage porcelain bushings. Our products strictly follow the traditional German standards of DIN42531, DIN42532, and DIN42533, and also meet the mandatory international high voltage bushing specifications of DIN EN50180 and IEC60137. We are the core high voltage insulation components for power transformers, wind power step-up transformers, box transformers, and traction transformers exported to Europe, the Middle East, and Southeast Asia.

The company is equipped with a complete set of CNC machining, high-voltage power frequency withstand voltage, lightning impulse, partial discharge, and airtight salt spray aging detection equipment, and implements a standardized three system quality control for the entire process. The flange outer diameter, oil tank opening size, bolt center distance, conductive rod specifications, and top wiring terminals of the entire series of high-voltage bushings are completely unified with the German standard module. The same voltage and current specifications can be directly exchanged with Siemens and other European and American original bushings without cutting or modifying the transformer oil tank, greatly reducing the cost of overseas whole machine modification and old equipment maintenance replacement.

1. Pure German standard uniform size, strong interchangeability and universality

The complete installation and electrical dimensions strictly comply with the German DIN high voltage standard, which is universal for oil transformers in various European countries. Old equipment can be replaced directly on site without changing the fuel tank or re opening the mold, greatly reducing maintenance and renovation costs.

2. Strict high-voltage testing throughout the entire process, ensuring safe and stable insulation

From raw material spectral detection, high-temperature sintering of ceramic parts, CNC precision machining, lightning impulse withstand voltage, partial discharge testing to finished product salt spray aging sampling, the entire quality can be traced, eliminating the hidden dangers of high-voltage operation flashover and breakdown.

3. Multi umbrella skirt anti fouling design, suitable for complex outdoor working conditions

The standard multi umbrella skirt structure can extend the creepage distance as needed, making it suitable for long-term stable use in coastal areas with high salt spray, mining areas with high dust, and high-altitude cold regions, reducing the frequency of maintenance and cleaning.

4. Two major structures are fully covered, suitable for various high-power transformers

The pole mounted model is suitable for small and medium-sized 10/20/35kV distribution transformers; The cable connected high current model is suitable for wind power boosting transformers and high-power models of power station main transformers, providing one-stop support for the entire machine.

5. The source has its own factory, with sufficient stock and fast delivery

Standardized high-voltage bushing production workshop, complete set of high-voltage testing equipment, 12/24/36kV regular specifications are readily available in stock, batch orders are quickly scheduled, and CAD dimension drawings and a full set of German standard factory inspection data are provided synchronously.

6. Support full dimensional non-standard customization

Our professional technical R&D team can customize extended conductive poles, special-shaped flanges, silver plated conductive parts, extended anti fouling umbrella skirts, and high-altitude special extended crawling high-voltage bushings according to overseas customer drawings, to solve various special working condition matching problems.
