Insulating tape is introduced

Insulating tape is introduced for insulating tape specifically to the electrical use used to prevent leakage, insulation effect of the tape. Manufacturing process: the polyvinylchloride (PVC) as the backing material, then coated with rubber pressure-sensitive adhesive. they are. Insulating tape for electrical use used to prevent leakage, insulation effect of the tape. Also called insulating tape, adhesive tape, composed of baseband and pressure-sensitive rubber. Baseband generally choose cotton cloth, synthetic fabric and plastic film, rubber made from rubber increase adhesion resin compound, good viscosity, excellent insulation function. Insulating tape with good insulation, weather resistance, flame retardant features such as voltage, characteristics, designed for connecting separated electrical wires for electrical insulating and protection purposes. In 380 v voltage insulating tape is widely used in the following use of wire wound, electrical insulation sealing, top job. Production technology has a brush glue and glue method two kinds. Insulating tape the use of the advantages and disadvantages: due to the direct use of plastic tape shortcomings more: plastic tape moment does a long easy dislocation, glue; Electrical load weight, fever, joint plastic tape is easy to melt to shorten; Mains connections in the terminal box kneading, connector have burr, easy scratches plastic tape, etc. These risks will directly endanger the personal safety, caused by short circuit, the formation of a fire. And use black insulation tape above will not happen, it must have the strength, flexibility, can tightly around for a long time, the joint is influenced by time and temperature and compact shape, will not fall off, and flame retardant. Moreover, with black tape wrapped around again after plastic insulation tape to moisture, rust. Has its drawbacks as well as insulating adhesive tape, of course, it has good waterproof function but easy to break, so eventually need to tie up as a protective layer, layer 2 plastic tape on the insulation of the joint and the joint adhesive with each other is not sticky, function better. Insulating tape with skill: in the process of electricity, although people noticed that the power cord material cross-sectional area of intrusive have influence on the safety of the electric, but tend to be joint use of insulating tape no notice. Power line installation is more and more cluttered now, walk under the wood floor, wall, diaphragm and damp underground or in the water. If the insulation tape used improperly, will attack the leakage, endanger personal safety. So we should correct use insulating tape, the power cord connection points '+' connection, '-', 'T' connection. Joint should be bound tightly, lubrication, no burr, otherwise, before the thread broken, should press gently with combination pliers, first round to the inlet pressure, then side, thread will break in disconnect joint. If the joint in a dry place, should be with black tape wrapped around 2 insulation layer, then wrap plastic tape 2 layer, then stretched around 200%, with insulation adhesive belt around 2 ~ 3 layers, finally put 2 layers of plastic adhesive tape.
