How to choose a good roll of electrical tape

 

  Electrical tape is used for insulating wire wrap thread, related to electrical safety, so choose a good roll of insulation tape, is an electrician must face every problem, a lot of the market PVC electrical tape, how to choose it ?

    First, from the appearance of working roll of tape, a roll of electrical tape good color should be uniform, cross-section should be smooth, not convex volumes, there is no glue overflow, because if there is an overflow of glue, glue tape to prove this already aging the use of such tape wound thread, had not much time will be self-released, causing serious consequences of leakage.

    Then, we can pull the tape, hand feel sticky peel strength and adhesive tape surface opened, in general, moderate peel strength tape can, too light, then a bad wound wire, too, then pull hard worker open and easy to pull the tape deformation. The sticky adhesive side is stronger, but it is not the more sticky the better, because it is the characteristics of rubber, plastic surface made rough to prove glue do sucks, very easy to stick rotten gums.

    Finally, we put tape stretched to twice as hard look at the tape in reverse, if the tape does not change color or only a little change occurs, the tape does not prove the substrate plus or just add a little filler, If the color becomes white tape to prove the manufacturers to reduce costs, in PVC substrates add a lot of filler, reduces the insulating properties of the tape.

    Therefore, the cross-section roll smooth, moderate viscosity, no or only a little anti-white electrical tape, electrical tape is a roll of good.

    Cohesion safety-oriented electrical tape, to provide users with safe products that meet the above conditions, and professional development, production, processing, marketing one-stop service, providing customers with cost-effective products, cohesion tape , worthy of your trust.
