Overview of the properties of
So, first, consider the properties of cotton insulation tape( CB).The main advantage of such an insulating tape is that it does not melt when the wire is heated, withstands mechanical loads and is not damaged in sub-zero temperatures. In addition, an important advantage of the product can be considered increased wear resistance - it is difficult to wipe during use. As for the disadvantages of CB insulation tape, the main one is considered to be a poor tightness of the material. In rooms with high humidity, as well as in the street it can not be used. In addition, the cotton fabric does not stretch and can withstand a voltage on the sample of not more than 1000 volts.
As for the analogue of polyvinyl chloride, the material has an increased resistance to moisture, it stretches well and withstands tensile stress up to 5000 Volts( better analog).The main disadvantage of PVC insulating tape can be considered the fact that it is not thermally stable,melt at high temperature. According to the technical characteristics of the product, the maximum operating temperature should not exceed +70 ° C( GOST 16214-86).In addition, the plastic insulation tape breaks down in the frost and loses its stickiness.
With the properties of rag and plastic insulating tape dismantled, now we still discuss what is better to use for insulation of wires in household electrical wiring - rag or plastic.
Which option should I prefer?
As cotton fabric better tolerates high temperatures, but is afraid of humidity, it is better to use it indoors: houses, apartments, etc. Previously, a cotton insulation tape was used in junction boxes, because a bad connection of the wires would eventually heat up, and this insulation would not melt and prevent a short circuit.
PVC product is best used for electrical wiring outdoors and in rooms with high humidity. In addition, you can isolate the plastic insulating tape of the wire from the chandelier, as well as in other places where there will be no strong heating of the veins.
In the car for reasons of accuracy, rags are more often used because of the insulation tape.it is black and does not catch your eye when you open the hood. To make such insulation sealed, a heat shrink tubing is put on top of the cotton fabric.
Well, experienced electricians, in order to "kill two birds with one stone", first isolate the wires of black CB with electrical tape, after which several layers of PVC are additionally wound up. In this case, the wiring will be protected from short circuit, as well.insulation will not melt, and from increased humidity.
By the way, the best manufacturers of products are considered to be such firms as ISOLOCK, TDM ELECTRIC and Klebebander. Professionals leave in most cases only positive feedback about the products of companies. A cheaper, but still high-quality insulation tape from IEK can also be selected for wiring in the house! In addition, we recommend that you watch a video that compares the quality of several manufacturers of insulation tapes:
Here we also talked about which electrical tape is better for wiring in the house and car. We hope, now you know what is more correct to choose in certain conditions: PVC or HB material and what are the advantages of each of the options!
