The basic construction of transformer is 100% Cu Wound With CRGO lamination & H class insulation.
|
The life of the Cu is 3 to 4 times more than the Al & also it withstands at more temperature than the Al.
|
CRGO lamination is preferred because of its high efficiency i.e., it consumes power Compared to CRNGO or BLACK SHEET Lamination.
|
The H class insulation is preferred because its with standing capacity is more i.e., Up to 180
