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 thermally 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
