Paper Insulation

Lappings of woodpulp or manila paper in tape form, frequently impregnated before or after application, are used to form part or all of the insulation on many types of wires and cables. Among other uses are power cables, telephone cables and winding wires. The paper tapes must be stored and applied under closely controlled humidity conditions, and applied with carefully designed tensions to avoid creasing and tearing of the insulation during winding.
