Electrical tape is used to insulate wire and thread. It involves electrical safety. Therefore, choosing a good insulating tape is a problem that every electrician has to face. There are many PVC electrical tapes in the market. How to choose it? ?
First of all, start with the appearance of this roll of tape. A good roll of electrical tape should have a uniform color. The cross section should be even, no bulge, and no glue spills out, because if the glue overflows, it proves that the tape's glue is aging. It will take a long time for the cords wound with this tape to loosen themselves and cause severe consequences of electric leakage.
Then, we can pull open the tape and feel the peeling force of the tape and the adhesiveness of the rubber surface by hand. In general, the stripping force of the tape can be moderate. If it is too light, it is not good to wind the wire. If it is too heavy, the worker can hardly pull. Open and easily deform the tape. The adhesive surface is more viscous, but it is not as sticky as possible, because in terms of the properties of the rubber, the fact that the surface of the glue is rough proves that the glue is very poor and that it is very easy to rot the glue.
Finally, we doubled the length of the tape and looked at the whitening of the tape. If the color of the tape did not change or only a small change occurred, the base material of the tape was not added or only a little filler was added. If the color of the tape becomes very white, it proves that in order to reduce the cost, the manufacturer adds a lot of filler in the PVC substrate, which reduces the insulation performance of the tape.
Therefore, a roll of flat, moderately adhesive, no or only a little anti-white electrical tape is a good electrical tape.
