As we mentioned earlier, all kinds of electrical works use PVC electrical insulation tape. This tape comes in varying widths and thicknesses. The thicker tapes are more economical and provide good insulation which makes them ideal for high voltage applications and mechanically stressed areas. Narrower tapes are best suited for insulating small gage wires. Owing to its easy stickability and mechanical tearability, simple electric insulation tasks make it a favorite of both professionals and casual users alike.
