Description

Feature

Parameter

Three-dimensional coil iron core liquid immersed distribution transformer: breaking through the traditional planar structure. The three-phase magnetic circuit is completely symmetrical, and the three-phase current is balanced; Smaller volume and weight, less material usage, and higher utilization rate of iron core materials; High reliability and long operating life. The three-phase magnetic circuit has no seams, and the magnetic flux direction is completely consistent with the crystal orientation of the silicon steel sheet, greatly reducing no-load loss, no-load current, and noise.

Low loss: Meet the energy efficiency requirements in the standard GB20052-2020 "Energy Efficiency Limits and Levels for Power Transformers";
Low noise: meeting the requirements of the low noise standard of the State Grid South Network;
Strong short-circuit resistance: Low voltage coils are wound with copper foil, while high voltage coils are solidified with adhesive paper, resulting in high mechanical strength;
Beautiful appearance: Full polishing and rust removal, powder electric spraying paint can achieve the spraying effect of household appliances;
