Product Brief

With a voltage class of 35 kV and transformer capacity ranging from 30 kVA to 20 000 kVA, this transformer is a 35 kV class insulated dry‑type transformer developed by our company on the basis of digesting and absorbing imported technologies. Its design and manufacture comply with standards including IEC 60076, GB 1094 and GB/T 10228. The product directly steps down 35 kV grid power supply to 400 V distribution power or 10 kV transmission power for end‑users. Thanks to its remarkable advantages, it has been adopted in an increasing number of projects.

Product Features of SCB‑series 35 kV Dry‑type Transformer

1. Land‑saving, enabling multi‑stage power transformation project construction and delivering prominent social benefits.
2. Reducing project investment and improving economic benefits.
3. Eliminating 10 kV power transmission and transformation links, thus significantly cutting operation and maintenance costs.
4. Adopting high‑voltage low‑current power transmission instead of low‑voltage high‑current transmission to reduce line losses and lower line operation costs.
5. 35 kV power supply is fed directly to power‑consumption centers, effectively improving power‑supply reliability.
6. Low losses, fully meeting requirements of national product standards and national energy‑saving standards.
7. F‑class insulation with temperature resistance of 155 °C. It features low temperature rise in actual operation and strong overload capability. It can operate continuously at 120 % overload under natural air cooling, and 150 % overload under forced air cooling.
8. Low noise, with an average noise reduction of approximately 20 dB compared with national standard limits.
9. Reliable performance, safe operation and convenient maintenance. It boasts high overall mechanical strength, strong short‑circuit withstand capability, good resistance to impulse over‑voltage and excellent moisture‑proof performance.
