Electrical tape full name is PVC electrical insulating adhesive tape, and some people call it electrical insulating tape or insulating tape. Electrical tape is suitable for the insulation of various resistance components. There are three types of general electrical insulation tapes, one is insulation black tape, the second is pvc electrical flame retardant tape, the third is high pressure self-adhesive tape, three kinds of functions. When choosing electrical insulating tape, how to determine the quality of electrical insulating tape?
Insulation black cloth
Only the insulation function, but not flame-retardant or waterproof, has now been phased out, and only in some civil buildings there are still people in use.
Pvc electrical flame retardant tape
It has three functions of insulation, flame retardancy, and waterproofness, but because it is a pvc material, it has poor ductility and cannot be tightly wrapped. The waterproofness is not ideal, but it is now widely used.
High-pressure self-adhesive tape
It is generally used in higher grade voltages. Because of its good ductility, it is superior to the second one in terms of waterproofness. Therefore, people also apply it to the low voltage field, but its strength is not as good as pvc electrical flame retardant tape. , Usually these two are used together.
The quality of the electrical tape should be determined from the outside, whether it is flawless, whether the tape is rewinded, whether it is affixed, whether there is burr on the tape, whether the tape is smooth or not. (There are many kinds of electrical insulating tapes. We will not introduce the quality of the tape. In most cases, it will also depend on the use of the situation). Looking at the glue, most of the glue has now evolved to environmental protection. The taste is very important. If it is pungent, it is more likely to be defective (not all tapes). Is there any anti-adhesion when it is used under the tape? After use, there is no adhesive residue. If the adhesive is on the product, this is the fatal point of defective tape.
Matters needing attention: PVC material is basically similar, mainly to look at glue, poor quality tape bandage after some time, then untie, you can see the separation of plastic and PVC material, looks sticky, very uncomfortable, and good quality The tape will not have this problem.
