What kinds of electrical tapes are there? How to judge the quality of electrical insulation tape
Electrical tape is called polyvinyl chloride electrical insulating adhesive tape, and some people call it electrical insulating tape or insulating tape. Electrical tape is often suitable for insulation of various resistance parts.
There are 3 types of general electrical insulating tapes, each of which has a function
There are three types of electrical insulation tapes:
One is the insulating black tape, which has only insulation functions, but is neither flame-retardant nor waterproof. It has been gradually phased out, and it is only used in some civil building electrical appliances.
The second type is PVC electrical flame-retardant tape, which has three functions of insulation, flame-retardant, and waterproof, but because it is made of pvc material, it has poor ductility, and the joints cannot be wrapped tightly, and the waterproofness is not Ideal, but it is now widely used.
The third type is high-voltage self-adhesive tape, which is generally used in higher voltages. Because of its good ductility and better waterproofness than the second type, people also apply it in low-voltage fields. , But because its strength is not as good as PVC electrical flame-retardant tape, these two types are usually used together.
How to judge the quality of electrical insulation tape when purchasing electrical insulation tape?
From the outside to see whether there are defects, whether the tape is rewinding, whether there are burrs in the cutting, and whether the tape is smooth or not The next thing depends on the usage.) Looking at the glue, most of the glue has evolved to environmental protection. The taste is very important. If it is pungent, it is more likely to be defective (not referring to all tapes). Whether there is anti-adhesion during use, and whether there is any residual glue after use. If the residual glue is on the product, this is the fatal point of the defective tape. The PVC material is basically the same, mainly depending on the glue. After the tape is wrapped with poor quality After a period of time, after untying it, you can see that the glue and the PVC material are separated, which looks sticky and uncomfortable, and good quality tape will not have this problem.
