Features of insulating tape:
Anyone who has worked in the electrical industry knows that the most widely used in electrical engineering and other industries is the insulation tape of the insulation tape manufacturer, which plays a role in insulation and electricity prevention. Insulating tape is even used in the home, and many people can use it for the wire connection at home, making it very safe.
At present, the insulating tapes of insulating tape manufacturers have been widely used in electrical work such as wrapping, joints, insulating and sealing of wires used below 380V. Very popular in the electrical industry.
The insulating tape of the insulating tape manufacturer is also called insulating tape, tape, etc. It is composed of a base tape and a pressure-sensitive adhesive. Its base tape is not as thin as the general sealing tape, generally cotton, synthetic fiber fabric and plastic film, etc., and the adhesive layer is also made of rubber plus tackifying resin and other compounding agents, which has good adhesion and excellent insulation performance. Performance point. What are the characteristics of insulating tape? Insulating tape has good insulation voltage resistance, flame retardant, weather resistance and other characteristics, suitable for wire connection, electrical insulation protection and other characteristics.
At present, insulating tapes have been widely used in electrical work such as wrapping, joints, insulation and sealing of wires used below 380V. Very popular in the electrical industry.
How to use insulating tape:
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. Nowadays, 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. So, how to use insulating tape correctly?
The power cord connectors are divided into "+" word connection, "-" word connection, "T" word connection, etc. 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.
Because the direct use of plastic tape has many disadvantages: the plastic tape is easy to misalign and open the glue after a long time; when the electrical load is heavy, the connector heats up, and the plastic tape is easy to melt and shrink; the power connector is squeezed in the junction box, and the connector has burrs. Stabbed plastic tape, etc.
These hidden dangers will directly endanger personal safety, cause circuit short-circuits, and cause fires. The above situation will not occur if the insulating black tape is used. It has a certain strength and flexibility, can be tightly wound around the joints for a long time, is compact and shaped under the influence of time and temperature, will not fall off, and is flame-retardant. Furthermore, wrapping it with insulating black tape and then wrapping it with plastic 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 at the end, two layers of plastic tape should be wrapped as a protective layer.
