OVERVIEW

lron core:

the iron core is made by crystal grain-oriented silicon-steelsheet, GEORG cross cut shear (made in West Germany) isadopted to cut the silicon-steel sheet with a 45*yoint seam;fold the sheet into a multistage roll cross-section to reducethe noise and power consumption.

Coil:

cyinder type for high voltage, cylinder type or fet tyoe foroww voltage, this can increase the ability to resist short circuitand strike; and the distribution of magnetc path is moreetional

the oil tank is made by fine cold-rolled steel sheets, GEORGOil tank:corrugation oil tank production.line is adopted, to meet environmental needs,then,antiseptic coating material isapplied on the surface, which can meet the requirements forpetroleum and chemical industry (much oil stain and manychemical substances). In addition, the corrugations not anypossess heat radiation function, but also meet therequirement for oil expansion and oil contraction tradernormal performance,The isolation from air guarantees alow aging speed of oil and a long life expectancy oftransformer.

Insulation structure:

oil-immersed distribution transformer adopts A-levelinsulation structure; high voltage coil and low voltage coilare concentric, the space between coils is cardboard sleevesmall oil clearance oil partition structure.
