Electrical tape is called PVC electrical insulation adhesive tape, also known as electrical insulating tape or insulating tape. Electrical tape is often applied to insulation of various resistance parts.

There are 3 kinds of electrical insulating tape in general, and three kinds of functions.

Electrical insulating tape is divided into three kinds:

One is insulating black rubber cloth, which is only insulated, but it is not flame-retardant and waterproof. It has been phased out now and is used only in some civil buildings.

The second kind is PVC electric flame retardant tape, which has three functions of insulation, flame retardancy and waterproof, but because it is the material of PVC, the ductility is poor, it can not wrap the joint very closely, and the waterproof property is not ideal, but it has been widely used now.

The third is high pressure self adhesive tape, generally used in high grade voltage, because of its good ductility, waterproof on the second kinds of better, so people also used it in the field of low pressure, but because of its strength less than PVC electrical flame retardant tape, usually these two kinds of use.

How to determine the quality of electrical insulating tape when selecting electrical insulation tape?

From the outside to see if there are defects, tape reel to stick, cut off the edge of the edge, whether smooth to see the tape material (electrical insulation tape has many kinds, do not introduce the quality of the quality evaluation, in most cases also have to see the use of the situation) in the look at the glue, now most of the glue has evolved to environmental protection. The road is very important, if it is very harsh, the possibility of the secondary is larger (not all tape), it is the adhesive tape when it is used, and if the adhesive is torn down, there is no residual glue. If the glue is in the product, this is the fatal point of the secondary adhesive tape. The PVC material is basically the same, mainly the glue and the poor quality. After the tape is bandaged for a period of time, then unlock, you can see the glue and PVC material separation, looks sticky, very uncomfortable, and the quality of the tape will not be the problem.
