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. If Non woven fabric tape is used improperly, it will cause leakage, endanger personal safety or cause fire. So, how to use Non woven fabric tape correctly?
Power cord connectors are divided into "ten" word connection, "-" word connection, "D" word connection and so on. The joint should be tightly wound, smooth and free of thorns. Before the thread is disconnected, you should press it lightly with the wire pliers, then wrap it to the mouth, and then swing it from side to side. If the joint is in a dry place, it should be wrapped in two layers with Non woven fabric tape, then two layers of plastic tape (also called PVC adhesive tape), and then two or three layers with J-10 insulating self-adhesive tape stretched by about 200% , And finally wrap two layers of plastic tape. Because the direct use of plastic tape has many disadvantages: the plastic tape will tend to be misplaced and open after a long time; when the electrical load is heavy, the joint will heat up, and the plastic tape will melt and shrink; the power supply joints are pressed against each other in the junction box, and the joints have burrs. It is easy to puncture plastic tape, etc. These hidden dangers directly endanger personal safety, cause moderate wiring and cause fire. However, the above situation will not occur if the insulating black tape is used. It has certain strength and flexibility, can tightly wrap the joints for a long time, and is dry and fixed under the influence of time and temperature, will not fall off, and is flame-retardant. Furthermore, wrapping with Non woven fabric tape and then wrapping tape can prevent moisture and rust. Of course, the insulating self-adhesive tape also has its defects. Although it has good waterproof performance, it is easy to break. Therefore, two layers of plastic tape must be used as a protective layer at the end.
Non woven fabric tape is made of non-woven fabric by calendering. It has good insulation and winding properties, low price, and aging resistance. Used in the joint wrapping of low-voltage lines, the insulation performance is stable, relatively heat-resistant, afraid of water, the insulation performance is reduced after being damp, and the insulation effect is lost after immersion in water. Self-adhesive plastic tape: high-quality insulation, good water resistance, is an electrical insulating material with a very wide range of applications, poor heat resistance, and has a good effect when used with Non woven fabric tape.
