In the process of electricity use, 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 do not pay enough attention to the use of Non woven fabric tape for connectors. If Non woven fabric tape is used improperly, it will cause leakage of electricity, endanger personal safety or cause fire. So, how to use Non woven fabric tape correctly?
The power cord connectors are divided into "ten" connection, "-" connection, "D" connection and so on. The joint should be tightly wound, smooth and free of thorns. Before disconnecting the end of the thread, use the wire cutters to gently press it, then wrap it to the mouth, and then swing it left and right, and the end of the thread will be disconnected at the joint very obediently. If the joint is in a dry place, first wrap it with two layers of insulating black cloth, then wrap it with two layers of plastic tape, then stretch it about 200% with J-10 insulating self-adhesive tape and wrap it in two or three layers, and finally wrap it with two layers of plastic tape. Because the direct use of plastic tape has many disadvantages: the plastic tape is prone to dislocation and glue opening over time; when the electrical load is heavy, the joints are heated, and the plastic tape is easy to melt and shrink; the power connectors are pressed against each other in the junction box, and the joints have burrs. It is easy to poke empty plastic tapes, etc. These hidden dangers directly endanger personal safety, cause moderate wiring and cause fire. The use of insulating black tape will not occur the above situation. It has certain strength and flexibility, and can be tightly wrapped around the joint for a long time. It is dry and fixed under the influence of time and temperature, will not fall off, and is flame retardant. Furthermore, wrapping with insulating black tape and then wrapping the tape can prevent moisture and rust. Of course, the insulating self-adhesive tape also has defects. Although it has good waterproof performance, it is easy to break, so it is necessary to wrap two layers of plastic tape as a protective layer.
Black Non woven fabric tape: It is made of cotton fabric and is made by calendering. It has good insulation and winding properties, low price and anti-aging. It is used to wrap the joints of low-voltage lines. It has stable insulation performance, is relatively heat-resistant, and is afraid of water. The insulation performance is reduced after being damp, and the insulation effect is lost after being soaked in water.
Self-adhesive plastic tape: high-quality insulation, good water resistance, is a very widely used electrical insulation material, poor heat resistance, good effect when used with black Non woven fabric tape.
Self-adhesive tape: It has good stretchability and self-adhesive properties, high waterproofness and sealing performance. It is used as a joint in deeper water. It is used in conjunction with black Non woven fabric tape, which is afraid of oil and sun.
