P. Leo Insulation Tape, the 3M & Permacel Alternative
Electrical Insulating tapes are used primarily on small to large coils and capacitors to provide mechanical holding power during the manufacturing process (typically varnish impregnation) or to provide insulation between layers of wire in similar wrapped coils. Various levels of thickness, tensile strength, and elongation coupled with dielectric strength and temperature class are distinguishing attributes for this category.
