Transformer Windings
With a fully kitted winding shop, BTT manufactures low voltage and high voltage winding from start to
finish. The windings provide protection and resistance to short circuit load, overvoltage peaks and
reduces thrust forces. BTT utilises lacquer or paper insulated winding wire and the winding machines
ensure constant winding tension. The inter-layer insulation is made of high quality diamond dot paper
or kraft paper, which can be thermal upgraded. Various coil winding configurations are available:
Obround coils
Round coils
Rectangular coils
Foil winding
Strip winding
Cross-over winding
Disc winding
Multi layered helical windings
