110kV Oil-Immersed Power Transformer
Product Description
The core of the 110kV oil-immersed power transformer is made of high-quality oriented silicon steel sheets stacked in multiple steps and coated with curing varnish, featuring low loss and low noise. The coils adopt inner and outer support strip structures, and high-strength hard paper tube structures are used between coils and between coils and the core, effectively ensuring resistance to sudden short-circuit impacts. The body and tank are positioned with an all-around positioning structure to ensure stability during transportation and operation, with an aesthetically pleasing 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.
