Description

Feature

Parameter

The 35kV oil immersed power transformer power system substation and 35kV user station use high magnetic conductivity oriented cold-rolled silicon steel sheets as the iron core, cake structure as the coil, molded insulation parts as the body, bell type oil tank, and expansion type oil storage tank, which have a beautiful and generous appearance.

Low loss: Meet the energy efficiency requirements in the standard GB20052-2020 "Energy Efficiency Limits and Levels for Power Transformers";
Low noise: The self cooling noise level will reach below 60dB;
Low partial discharge: The partial discharge volume should be controlled below 100pc;
Strong short-circuit resistance: The coil is internally supported by a high-quality insulation skeleton, and the side wall of the fuel tank is formed by laser cutting in one go;
Beautiful appearance: Full polishing and rust removal, powder electric spraying paint can achieve the spraying effect of household appliances;
No leakage: All sealing flanges adopt groove structure, the oil drain valve adopts copper valve, and the radiator adopts vacuum butterfly valve to ensure sealing performance.
