Teach you select good electrical tape electrical tape to teach you to pick a good tape: electrical tape is used for wire wound and the insulation of the thread, involve the electric safety, so, choose a good insulating tape, is each electrician are faced with the problem, many on the market of PVC electrical tape, has excellent wear resistance, moisture resistance, acid and alkali resistance and environmental change to ( Contains ultraviolet) 。 Polyvinyl chloride (PVC) with high dielectric strength, in good shape, less dosage can obtain better mechanical maintenance. Use: used for binding wire and cable is suitable for indoor or outdoor used to under 600 v voltage level of all wire and cable connector of the main insulation used in repairing sheath of hv cable joint for 600 v and below the electrical wire and cable insulation met standard color. First, start from the appearance of the roll of tape, a roll of good electrical tape, and color should be uniform, cross 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 too long before will himself to loosen, the consequences of formation leakage. And then, we can spread out the tape, feel the tape by hand spread out the peel strength with the sticky glue, generally speaking, the adhesive tape peel strength can moderate, too light to owe good round wire, very difficult to spread out the workers and simple 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 let 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 tape color 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, no or just a little white electrical tape, is a roll of good electrical tape.
