Detailed Product Description General:This series of products is mainly applied to important locations of special fireproofrequirement, such as commerce mansion, high-rise, airport, industrial and miningfactory, power plant, oil field, railway, tunnel, etc. It can also be usedtogether with switchgears as box-type substation. Performance characteristics:1 Safe, fireproof, pollution free, and can be used in the load center directly.2 High mechanical strength, strong short-circuit withstand capacity, small partialdischarge, excellent thermal stability, high reliability and long service life.3 Low losses and noise, and excellent energy saving4 Good heat radiation, great overload capacity, and overload capacity improved whenforced air cooling is applied.5 Good anti-humidity, suitable for operating in high humid and harsh environment.6 Protecting environment, flame-retardant, explosion-proof and free of maintenance.7 Small size and light weight.Structure features:1 LV winding of epoxy resin casting dry-type transformer is made of foil. It adoptsexcellent imported copper foil. HV winding is trapezoid subsection layers typestructure, molded with epoxy resin cast in vacuum and low voltage between thelayers is low, so it has good over-voltage withstand capacity.2 Iron core is made of imported high quality, cold-rolled, granule-oriented silicon-steelsheets and machined with completely automatic cutting line, superposedwith 45 ix-level overall bias seams. Core column adopts special binding technique.The surface of iron core is paint with the special rustproof coating to resisthumidity and rust, which can effectively reduce the no-load losses, no-load currentand iron-core noise.
