Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics, but vinyl is most popular, as it stretches well and gives an effective and long lasting insulation. Used for insulation, protection, fixing, maintenance, colour coding and more, Good resistance to abrasion, moisture, chemicals, and varying weather conditions, highly flexible with good adhesion level, Harnessing of wires and cables. The use of high-quality insulating tapes provides optimum protection against dust, UV radiation, moisture, dirt, acids, alkalis and solvents, and is possible in a broad range of temperatures. It is tough to beat the efficiency, speed, durability and safety of taping, sealing and padding work. The primary tapes used in electrical applications are vinyl, rubber, mastic, and varnished cambric.” Electricians generally use only black tape for insulation purposes. The other colors are used to indicate the voltage level and phase of the wire. (In fact, the colored tape is referred to as “phasing tape”.) This is done on large wire which is available only in black insulation. When wires are phased, a ring of tape is placed on each end near the termination so that the purpose of the wire is obvious.
