1. a kind of dry-type transformer of low power consumption comprising low-voltage coil that is cored, being sleeved on outside iron core, is sleeved on low pressureHigh-tension coil, babinet, high-voltage leading-out wire, low pressure lead-out wire, bushing, low-tension bushing outside coil are used in low-voltage coilLow pressure enameled wire has used high pressure enameled wire in high-tension coil;

  • It is characterized in that, the low pressure enameled wire is by conductor layer and packetThe insulating lacquer layer overlayed on outside conductor layer is formed, and the cross section of conductor layer is round, and the cross section of insulating lacquer layer is round, insulated paintThe cross-sectional area of layer is 0.1~1.5 times of cross-sectional area of conductor layer, the conductor layer by weight, by following raw materialIt forms:

    20~30 parts of copper, 60~80 parts of aluminium, 2~4 parts of boron, 1~3 part of silicon, 1~2 part of manganese, 0.1~0.4 part of magnesium, silver 0.1~0.3Part, 0.1~0.2 part of zirconium, 0.1~0.2 part of chromium, 0.3~0.6 part of zinc, 0.1~0.2 part of yttrium, 0.2~0.4 part of titanium, beryllium 0.1~0.2 part, 0.1~0.2 part of rhenium, 0.1~0.3 part of tungsten, 0.1~0.3 part of gallium, wherein, in mass ratio, copper:









    The insulating lacquer layer by weight, by following originalMaterial is formed:

    70~80 parts of dimethylacetylamide, 8~10 parts of ethyl alcohol, 7~9 parts of polyamic acid, 2~4 parts of cobalt naphthenate, to benzene1~3 part of dioctyl phthalate butanediol ester, 5~10 parts of silicon carbide, 8~14 parts of '"'"'-diphenylmethane diisocyanate, poly- amino resins 3~7Part, nylon 6 or nylon 12:

    3~6 parts, 6~9 parts of ethyl acetate, 1~2 part of butyl acetate, 3~5 parts of acetic acid, mica 10~15Part, 2~4 parts of 4~6 parts of fireproof varnish, the dibutyl tin laurate of 1~1.5 part of alundum (Al2O3), model G60-95.
