35kV Oil-immersed Power Transformer
Product Description
The 35kV oil-immersed power transformer is suitable for power system substations and 30kV user substations. The core is made of high-permeability, high-quality grain-oriented cold-rolled silicon steel sheets. The coils adopt a disc-type structure, the body uses molded insulation components, and the tank is of bell-type design with an expansion oil conservator, offering an elegant and generous appearance.

Product Advantages
Low loss
Complies with the energy efficiency requirements of GB20052-2024 "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Power Transformers"
Low noise
The self-cooling noise level will be below 60 dB;
Low partial discharge
The partial discharge level is controlled below 100 pC;
Strong Short-Circuit Resistance
The coil interior is supported by high-quality insulating frames, and the tank side walls are laser-cut in one pass;
Attractive Appearance
Full polishing and rust removal, with powder electrostatic spraying achieving a finish comparable to household appliances.
No Leakage
All sealing flanges adopt a groove structure, the oil drain valve is made of brass, and the radiator uses a vacuum butterfly valve to ensure sealing performance.
