Product Description

The core of 110kV oil-immersed power transformer is made of high-quality oriented silicon steel sheets stacked in multiple steps, and the surface is coated with curing paint. It has the characteristics of low loss and low noise. The coil adopts an internal and external support structure, and a high-strength hard paper tube structure is used between the coil and the core, and between the coils, so as to effectively ensure the ability to resist short-circuit impact. The oil tank adopts a one-time forming bending corrugated structure to increase the mechanical strength and beautiful appearance. The all-round positioning structure is adopted between the body and the oil tank to ensure transportation and operation stability.

Low loss: in line with the energy efficiency requirements of GB20052-2020 “Energy Efficiency Limit Values ​​and Energy Efficiency Grades of Power Transformers” standard;
Low noise: the self-cooling noise level will reach below 60dB;
Low partial discharge: the partial discharge volume is controlled below 100pc;
Strong short-circuit resistance: the coil is supported by a high-quality insulating skeleton, and the side wall of the oil tank is formed in one step by laser cutting;
Beautiful appearance: full polishing and rust removal, powder spraying can achieve the effect of home appliance spraying;
No leakage: the sealing flanges all adopt a groove structure, the oil drain valve adopts a copper valve, and the radiator adopts a vacuum butterfly valve to ensure sealing performance.
