Dry-type Transformer LV Foil Winding Machine
I Description of dry-type transformer LV foil coil winding machine:
BRJ series foil coil winding machine is for winding foil type coils in transformer and electric apparatus.
There are usually three kind of foil coil width: 1400mm, 1100mm and 800mm. Also there are double-foil type machines.
Foil coils use copper or aluminum foil as conductor, broad strap type insulation as interlaminar insulation; narrow strip type insulation of terminal insulation. They are winded to be roll type coils. Also, the inside and outside down-leads will be welded and the outer surface will be wrapped.
So, one machine can finish all the requirements for foil coils.
