35kV oil‑immersed transformer covers 1000kVA–10000kVA and adopts environmental biodegradable vegetable oil as cooling and insulation medium. It features high efficiency, low loss, sealed corrugated tank, strong short‑circuit withstand and high safety. With eco-friendly, non-toxic and recyclable advantages, it effectively reduces fire risk and environmental pollution.
Adopting optimized core and winding design, the transformer runs stably with low noise and long service life. It is widely used in urban grids, industrial parks, hydropower stations, tunnels and other environmental‑sensitive power supply scenarios, providing safe and reliable power distribution for key projects.
