Wrapping tape on a high voltage cable can be time consuming and error prone since the careful build-up of tape requires accurate half-lapping and constant tension in order to reduce build-in air voids. Rubber tapes are designed to stretch−some up to 1000%. Elongating the tape this way drives to compression, and that results in the strong self-fusion that provides great insulation and moisture protection.
If you’re unfamiliar with reasons why people use electrical tape over other more basic tapes, there are a few factors that make it stand out among the rest:
In addition to different densities, polyethylene film tapes are available in different thicknesses, widths, lengths, and colors.
