Electrical tape is suitable for all kinds of insulation resistance parts. General electrical insulating tape has 3 kinds, one kind is black insulation tape, the second is electric flame retardant PVC tape, high pressure, for a third since the adhesive tape, three have different functions. The choose and buy the electrical insulating tape, how to judge the stand or fall of electrical insulating tape? Electrician tape has what kinds of how to judge the stand or fall of electrical insulating tape electrical tape classification of electrical insulation tape is divided into three kinds: one kind is black insulation tape, as long as the insulation function, but not flame retardant is not waterproof, now has been gradually screened, as long as there is in some civil construction electrical people in use. The second is electric flame retardant PVC tape, it has a waterproof insulation, flame retardant, and three kinds of function, but because it is PVC material, so the poor ductility, cannot joint package is very close, water proofing property is not very ambitious, but now it has been widely used. The third is a high pressure since the adhesive tape, general use on the level of high voltage, because of its good ductility, more astonishing than the second on the waterproof, so people also apply it in the category of low pressure, but because it is the strength of PVC electrical fire retardant tape, general quality of these two kinds of cooperation with electrical tape to identify if there is a flaw when viewed from the outside, whether the tape after docile, whether did cutting burrs, smooth the tape raw materials ( There are all kinds of electrical insulating tape, not introduce raw material quality evaluation one by one, in most cases also depends on the application) In the glue, glue now most now to the evolution of environmental protection, taste is very important, if very blunt nose, it is the possibility of more defective items ( Not all the tape) , is in with tape down there is no back stick, did off residue after use, if the glue on the product, this is the fatal defect tape some considerations for PVC materials basically the same, basically be to see glue, poor quality of adhesive bandage after a period of time, to unlock, can see the glue and PVC material separation, looks sticky sticky, very uncomfortable, and good quality tape will not appear this kind of problem.
