Product Parameters
Parameters:
Iron core:theiron core is made by crystal grain-orientedslicon-steel sheet;GEORG crosscut shear(made in West Germany)is adopted to cut the silicon-steel sheet with a 45°joint seam;fold the sheet into a multistage rotmd cross-section to reduce the noise and power consumption.
Coil:cylinder type for high voltage;cylinder type or foil ype for low voltage;this can increase the ability to resist short circuit and strike;and thedistribution of magnetic pathis more rational.
Ooil tank:the oil tankis made by fine cold-rolled steel sheets;GEORG corrugation oil tank production-ine is adopted;to meet environmental needs,then,antiseptic coating material is applied on the surface,which can meet the requirements for petroleum and chemical industry (much oil stain andmany chemica substances.In addition,the corrugations not any possess heat radiation function,but also meet the requiement for oilexpansion and oilcontraction trader normal performance.The isolation from air guarantees a low aging speed of oil and a long life expectancy of transformer.
Insulation structure:oi-immersed distibution transformer adopts A-levelinsulation structure;high voltage coil and low voltage coil are concentic,thespace between coils is cardboard sleeve small oil clearance oil partition structure.
