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 wondering which tape should you buy, consider self-adhesive butyl tape. It’s much easier to install, meaning no fiddly application and less chance of getting yourself stuck.
