Electrical insulation tape is divided into three types:

One is insulated black tape, only the insulation function, but not fire-retardant is not waterproof, and now has been gradually eliminated, and only in some civil construction electrical also some people in use.

The second is pvc electrical flame retardant tape, it has insulation, flame retardant, and waterproof three functions, but because it is pvc material, so the ductility is poor, can not be wrapped very tight joints, water resistance is not very good, But it has now been widely used.


The third is a high-pressure self-adhesive tape, generally used in the higher level of voltage, because of its good ductility, waterproof than the second better, so people also apply it in low-voltage areas, but because Its strength is not as good as pvc electrical flame retardant tape, usually these two kinds of use


What kind of electrical tape how to determine the electrical insulation tape is good or bad

Tools / raw materials - Electrical tape procedures / methods

From the outside to see if there are flaws, tape rewinding is obedient, cut whether there is no burr, whether it is smooth to see the tape material (electrical insulation tape there are many types, not one by one to introduce the material quality evaluation, in most cases Look at the use of) look at the glue, and now most of the glue has been evolved to the environmental protection, the taste is very important, if it is pungent, is the possibility of defective product is relatively large (not all tape), when the tape is used There is no anti-stick, after the use of torn off there is no residual glue, if the residual glue on the product, this is the defective tape Note that PVC material is basically the same, mainly to see the plastic, poor quality bandage after a period of time, And then unlock, you can see the glue and PVC material separation, looks sticky, very uncomfortable, and good quality tape will not appear this problem.
