foil coil winding machine for foil type low-voltage coils in transformer and reactor.
Max. foil width: 800mm
Full automatic!
BRJ-800 foil coil winding machine is for winding foil type coils in transformer and electric apparatus.
The max. foil coil width is 800mm.
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.
