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;
