What happens if the cable insulation thickness is not standard?

First, too thin: It will reduce the service life of cable products

After long-term operation, directly buried, immersed in water, exposed to air or easily corroded environment, the thinnest point of the insulation may broken down due to corrosion of the external medium for a long time. In addition, the long-term electrification of cable will generate a large amount of heat, the conductor is allowed to work at 70 ° C, and the long-term use temperature of PVC should not exceed 65 ° C.

Second, too thick: It will increased the difficulty when install

At present, more and more environmental require high-voltage cable products to have a small outer diameter. In the process of installing, it is necessary to consider leaving space which could dissipate the heat generated .Too thick insulation will also increase the difficulty when installing. So that it should be strictly according to relevant standards, otherwise it can not protect cable.
