What is Insulation tape?

2020/08/31

Insulation tape refers specifically to the tape used by electricians to prevent leakage and provide insulation. Also called insulation tape, tape, composed of base tape and pressure-sensitive adhesive layer. The base belt is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber plus tackifying resin and other compounding agents, which has good viscosity and excellent insulation performance. Insulation tape has good insulation and pressure resistance, flame retardant, weather resistance and other characteristics, suitable for wire connection, electrical insulation protection, etc.

In the process of using electricity, although people have noticed that the size of the cross-sectional area of the power cord material has an impact on the safe use of electricity, they often pay insufficient attention to the use of insulation tape for the joints. The laying of power lines is becoming more and more complicated, and it can be found under wooden floors, in walls, in partitions, and in wet ground or water. If the insulation tape is used improperly, electric leakage will occur, endangering personal safety.

 

Therefore, we must use insulation tape correctly. The power cord connectors are divided into "+" word connection, "-" word connection, and "T" word connection. The joint should be tightly wound, smooth and free of burrs. Otherwise, before disconnecting the thread, use wire cutters to press it lightly, then wind to the pressure port, and then swing left and right, the thread will be compliantly disconnected at the joint. If the joint is in a dry place, first wrap 2 layers of insulating black tape, then 2 layers of plastic tape, and then stretch it about 200% with insulating self-adhesive tape, wrap 2 to 3 layers, and finally wrap 2 layers of plastic tape.
