1. electrical tape full name of polyvinyl chloride electrical insulation tape, also known as electrical insulation tape or insulation tape. 

2. Applicable to the insulation of various resistance parts. Such as wire joints winding, insulation damage repair, transformers, motors, capacitors, voltage regulators and other types of motor, electronic parts of the insulation protection. Can also be used in the industrial process of binding, fixing, lap, repair, sealing, protection. 

3. power cable connectors are divided into "ten" connection, "a" connection, "d" connection, etc.. Joints should be wrapped firmly, smooth and thornless. Before disconnecting the line, you should first use the wire clamp wire light pressure, then wrap to the mouth, and then swing around, the line will be obedient to the joint disconnected. If the joint is dry, it should be wrapped in two layers of insulating black cloth, then wrapped in plastic tape (also called PVC tape) two layers, followed by J-10 insulating self-adhesive tape stretched about 200% wrapped in two or three layers, and finally wrapped in two layers of plastic tape. Because the direct use of plastic tape drawbacks: plastic tape over time easy to misalignment, glue open; heavy electrical load, the joint heat, plastic electrical tape is easy to melt shrinkage; power supply joints in the junction box pressure each other, the joint has a burr, it is easy to poke empty plastic tape, etc., these hidden dangers directly endanger personal safety, causing a short circuit or abnormal wiring, resulting in fire.
