Product Description

In the transformer winding there is a zigzag oil guide structure so as to fully cool all areas inside the winding ,lower the temperature rise of the winding and the hot points of the winding and [rolong the service life of insulation.the HV and MV regulation system are independently provide with voltage regulating winding to balance the ampere turn of each winding effecticely lower the axial electrodynamic force generated at short circuit of transformer and improve abrupt short circuit withstanding capacity.

The core is made of high permeable grain orientated top quality coid rolled silicon sheet and the materical is cut with advanced germany geoge gmbh automatic shear line with the cut burrs controlled within 0.002mm.

The sillicon sheet fabrication adopts no-upper yoke lapped technology and all lapped joints of the sillicon sheet are 45 c full miters.the laminated core sheets are integrally pressed and adhered with epoxy resin to make the three leg two yoke core a strong and flat integral one with good verticality precision ,this effectively improves no ;oad performance and reduces noises.

The tank wall adopts wide steel sheet,which will be folded into corrugated structure without splicing,in this way welds are decreased and mechanical strength id enhanced ,meanwhile ,the corrugated wall has deverging effect ,and thus plays a role in dectease of noise .the routing troughs and control cabinets of the secondary circuit are all made of stainless steel.so the entire transformer has a simple and good looking .

All sealing surfaces use quality sealing material and are precision machined
