What kind of electrical tape are there? How to judge the stand or fall of electrical insulating tape
< br / >
electrical tape, PVC electrical insulating tape, also some people call it the electrical insulating tape or electrical tape. Electrical tape is suitable for all kinds of insulation resistance parts.
there are three general electrical insulating tape, three have different functions
electrical insulating tape is divided into three kinds:
the first is a black tape, insulation insulation function only, but not flame retardant is not waterproof, is now gradually eliminated, only on some civil construction electrical with others.
the second is electric flame retardant PVC tape, it has the function of waterproof insulation, flame retardant, and three, but because it is PVC material, so the poor ductility, cannot joint package is very strict, water proofing property is not very ideal, but it has now been widely used.
the third kind, high pressure since the adhesive tape, general use on the level of high voltage, due to its good ductility, is more excellent than the second on the waterproof, so people also apply it in the field of low pressure, but because of its strength than PVC flame retardant tapes, usually the two cooperate to use.
when the choose and buy electrical insulating tape, how to determine a good electrical insulating tape?
if there is a flaw when viewed from the outside, whether the tape after docile, whether did cutting burrs, smooth the tape material ( There are all kinds of electrical insulating tape, not introduce material quality evaluation one by one, in most cases also depends on usage) In the glue, glue most is now to the evolution of environmental protection, taste is very important, if very pungent, is the possibility of more defective items ( Not all the tape) , under is tape pull use was not sticky, did off residue after use, if the glue on the product, this is the fatal defect tape some matters needing attention of PVC material basically the same, basically be to see glue, poor quality of the adhesive bandage after a period of time, to solve, you can see glue and PVC material separation, and looks sticky sticky, very uncomfortable, and good quality tape will not appear this kind of problem.
