What are the three types of electrical insulation tape?

Electrical insulation tape is divided into three types:


The first kind is the insulating black cloth, it generally only has the insulating function, but does not be flame-retardant or waterproof, now on the market has already eliminated gradually, only in some civil buildings still has the electrical use.


The second is pvc electrical flame retardant tape, which has three functions of insulation, flame retardant, and waterproof, but because it is pvc material, so the ductility is poor, or can not be tightly wrapped joints, and waterproof Sex is not ideal, but it is now widely used.


The third type is a high-pressure self-adhesive tape. This type of tape is generally used on higher voltage grades. It is because of its good ductility and better waterproof than the second type. Therefore, people also apply it to low voltage. The field, but because its strength is not as good as pvc electrical flame-retardant tape, usually both of these need to be used together.


These three are all electrical insulating tapes, each of which is different, and both of them have their own advantages.
