How to Choose Electrical Tape

Time:2016-1-21 11:07:19

There are three kinds of electrical insulating tapes: one kind is the insulating black tape, which has insulation function only, but not flame retardant and water proofing functions, and it is now gradually eliminated, only used in some civil architecture electrics. The second kind is PVC electrical non-flammable tape, which features insulation, flame retardant and water proofing, however, the ductility of PVC  material is poor, it cannot wrap the connector closely, so its waterproofness is not ideal, but it has now been widely used. The third kind is high pressure self-adhesive tape, which is used in higher voltage, because of better ductility, it is better than the second kind of tape in regard to the waterproofness, so also apply it in the field of low voltage, however, its strength is inferior to PVC electrical non-flammable tape, they are usually used cooperatively.


To judge a tape, first of all, pay attention to its appearance, whether there is any defect, whether the tape rewinding is submissive, whether there are cutting burrs, whether it is smooth; pay attention to the tape material (there are many kinds of electrical insulating tapes, we shall not introduce them one by one, in most cases, they should be used in accordance with specific conditions); pay attention the glue, at present, most kinds of glue are environmentally friendly, if the smell of the glue is pungent, most likely it is inferior-quality product (not absolutely) , to see whether the tape is sticky chaotically after being pulled, whether there is residual glue after being torn down, and the residual glue is a fatal defect of inferior-quality tape.
