 Insulation tape winding method
 
In the process of using electricity, people have noticed that the size of the cross-sectional area of ​​the power line material has an impact on the safe use of electricity, but they often do not pay enough attention to the use of insulating tape on the joints. If the insulating tape is used improperly, it will cause leakage and endanger personal safety or cause fire. So, how to use insulating tape correctly? The power line connector is divided into "decimal" connection method, "-" word connection method, "D" word connection method and so on. Joints should be tight, smooth and thornless. Before disconnecting the wire, it should be lightly pressed with wire pliers, then wound to the mouth, and then swinging left and right, the thread end will be very obediently disconnected at the joint. If the joint is in a dry place, it should be wrapped in two layers of insulating black cloth, then wrapped in two layers of plastic tape (also called PVC adhesive tape), and then J-10 insulation self-adhesive tape stretched about 200% wrapped two or three layers, Finally wrapped two plastic tapes. Because the direct use of plastic tape has a lot of drawbacks: Plastic tape is prone to gum misalignment and open during a long time; When the electrical load is heavy, the joint heats, the plastic tape is easy to melt and shrink; the power connector is pressed in the terminal box, the connector has a burr, it is It is easy to poke plastic tapes, etc. These hidden dangers directly endanger personal safety, causing moderate lines and causing fires. The use of insulating black tape will not appear the above situation, it has a certain strength, flexibility, can be tightly wrapped in the joints for a long time, by time and temperature and dry fixed type, will not fall off, and flame-retardant. Furthermore, wrapping the tape with an insulating black tape can prevent moisture and rust. Of course, the insulating self-adhesive tape is also defective. Although it has good waterproof performance and is easy to break, it is necessary to wrap the two layers of plastic tape as the protective layer, and the self-adhesive tapes of the joints and the joints are not sticky to each other and have better performance.
 
Black cloth: Made of cotton cloth as base material, it 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. The insulation performance is stable, and it is more heat-resistant. It is afraid of water. The insulation performance after damp is reduced, and the insulation is lost after water soaking. Self-adhesive plastic tape (waterproof tape): Excellent insulation, good water resistance, is a widely used electrical insulation material, poor heat resistance, and with the use of black plastic cloth with good results. The
Self-adhesive tape: good, ah, stretching and self-adhesive performance, high water resistance and tightness, used in deeper underwater joints, with black plastic tape with the use of fear of oil afraid of the sun.
