DESIGN & CONSTRUCTION

 

 General


The transformer shall be of robust design and all materials used shall be guaranteed having no
harmful effects to the operators in the short and long term.


 Windings


 Winding Conductor


All windings shall be made of copper or aluminium conductor and shall be disposed
concentrically around the magnetic circuit limbs. The enamel coating if used shall be suitable
for the insulation system with minimum thermal Class F insulation.

 

HV Winding


The winding conductor shall be made of copper or aluminium wire, foil or strip. No joints shall
be permitted for the winding except for joints to external connection. The winding shall be
embedded in solid epoxy resin insulation. During manufacturing process, the winding shall be
impregnated and cast under vacuum with the epoxy resin and reinforced with glass fibre or
quartz powder. The content of the glass fibre or quartz powder shall be equal or higher than
60% and shall be evenly distributed to ensure mechanical strength both axial and radial
direction and to ascertain a high level of short circuit withstand capability as well as to avoid
the possibility of any crack caused by mechanical stresses due to temperature variations, or
sudden load peaks.

Executed standards
IEC60076-11, DIN42523
