Insulated rubber tape refers to the tape used by electricians to prevent leakage and provide insulation. Also known as insulating tape, tape, composed of base tape and pressure-sensitive adhesive layer. The base tape 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. Insulating tape has good insulation and pressure resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation, and heat insulation protection.
Insulating tape is widely used in electrical work such as wrapping, joints, insulation and sealing of wires used below 380V. There are two production processes: rubbing method and coating method. Production process: Polyvinyl chloride film is used as the base material and coated with rubber-type pressure-sensitive adhesive.
Electrical insulation adhesive tape, commonly known as electrical tape (hereinafter referred to as insulation tape), is a special adhesive tape used for electrical wiring and other insulation. In the past, adhesive tape-type insulation adhesive tapes have been used on electrical wiring, that is, black. Insulating tape, the base tree (back material) is woven cloth impregnated with insulating material. With the advancement of science and technology and economic development, many types of insulating tapes have emerged, but the main ones are: polyvinyl chloride and polyolefin insulating tapes.
Method of operation
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 insulating tape for the joints. The laying of power lines is becoming more and more complicated, and it can be found under the wooden floor, in the wall, in the partition, and in the damp ground or water. If the insulation tape is used improperly, electric leakage will occur, endangering personal safety. Therefore, we must use insulating 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 the thread is disconnected, first 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.
