The full name of electrical tape is polyvinyl chloride electrical insulating tape, which refers to the tape used by electricians to prevent leakage and play an insulating role.

It is based on polyvinyl chloride film and coated with rubber pressure sensitive adhesive. In terms of performance, electrical tape has good insulation, fire resistance, voltage resistance, cold resistance and other characteristics. In color, it has red, yellow, blue, white, green, black, transparent and other colors. In addition, it is suitable for wire winding, insulation fixing of transformers, motors, capacitors, regulators and other motor and electronic parts; it can also be used for binding, fixing, lapping, repairing, sealing and protection in industrial process.

But we should pay attention to the defect of electrical tape. Although it has good waterproof performance, it is easy to break. So we need to wrap two layers of plastic tape as a protective layer at last. The insulation self-adhesive tape between the joint and the joint is not sticky to each other and has better performance.
