Heat dissipation from power cables

Heat dissipation from power cables

When a strong current is passed through a high voltage cable, heat and power loss occur. If the heat level gets too high, it can have a negative effect on the life of the cable, and you may also risk the product warranty lapsing.

Turning it around, it is fair to say that when the temperature of a live cable is reduced, the power loss is reduced. The power thus reaches the consumers, rather than being wasted, which saves money and is good for the environment.


In principle, bentonite has an unlimited life and will retain its flexible sealing properties in wells and boreholes for as long as the product is underground in its natural environment and moisture conditions. Even if soil layers and rocks move over time or tree roots penetrate the bentonite, it will constantly repair itself and seal up again.

The main function of these products is to improve thermal conductivity, but there are a number of other properties that must also be in place for the material to work in practice.
