How to choose the high quality electrical tape? Electrical tape is used for wire wound and the insulation of the thread, involves the safe use of electricity, so, choose a good insulating tape, is each electrician to face problems, many on the market of PVC electrical tape, how to choose? First of all, start from the appearance of the roll of tape, a roll of good electrical tape, and color should be uniform, the section should be flat and not convex volumes, there is no glue overflowing, because if have glue overflow, prove the tape glue has been aging, use the tape around the threads, not the long time will own loosen, caused the leakage of serious consequences. Then, we will be able to spread out the tape, feel the tape by hand spread out the stripping strength with the sticky glue, in general, tape stripping strength is moderate, too light not round wire, big a simple workers hard to pull out and pull tape deformation. Rubber surface viscosity is better some, but also not the glue the better, because in terms of the characteristics of rubber, rubber surface do rough proof glue do very bad, is very simple rotten glue to stick. Finally we put the tape twice as hard to long, look at the tape reverse condition, if the color of the tape does not change attack may only attack a little change, prove the tape base material without maybe just a little bit of filling material, if the color of the tape becomes very white, prove that the manufacturers to reduce costs, add a lot of filling material in PVC base material, reduces the tape insulation function. So, a roll of flat section, moderate viscosity, there is no or only a little white electrical tape, is a roll of good electrical tape.
