Product Description

Honle Hermetically Sealed Oil-Immersed Power Transformer With Dual-Winding Off- Circuit-Tap-Changing
 

Iron core:
the iron core is made by crystal grain-oriented silicon-steel sheet;GEORG cross cut shear (made in West Germany)is adopted to cut the silicon-steel sheet with a 459joint seam; fold the sheet into a multistage roll cross-section to reduce the noise and power consumption.

Coil:
cylinder type for high voltage;cylinder type or foil type for low voltage;this can increase the ability to resist short circuit and strike;and  the  distribution  of  magnetic  path  is  more rational.

Oil tank:
the oil tank is made by fine cold-rolled steel sheets;GEORG corrugation  oil  tank  production-line  is  adopted;to  meetenvironmental   needs,then,antiseptic   coating   material   is applied on the surface,which can meet the requirements for petroleum and chemical industry (much oil stain and many chemical substances).In addition,the corrugations 
not any possess    heat    radiation    function,but   also    meet   the requirement  for  oil  expansion  and  oil  contraction trader normal  performance.The  isolation  from  air  guarantees  a low  aging  speed   of  oil  and  a long  life  expectancy
of transformer.

Insulation structure:
oil-immersed    distribution    transformer    adopts    A-level insulation structure;high voltage coil and  low voltage  coil are concentric;the space between coils is cardboard sleeve small oil clearance oil partition structure.
