HEAT DISSIPATION FROM POWER CABLES

CABLE TEMPERATURE MATTERS

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.

THE RIGHT PRODUCT FOR EVERY PROJECT

When a high voltage cable is laid in the ground inside a conduit, the heat dissipation around the cable is reduced and the temperature rises.

This situation can be improved by filling the cavity between the cable and the conduit with a heat dissipating material. The level of thermal conductivity required from the material depends on the nature of the project. We offer a range of products with varying degrees of thermal conductivity to match the needs of your project.

Below is a little more information about some of the things to consider when choosing a material for heat dissipation around electric cables.

DANTOCON THERMAL R

HEAT DISSIPATING CABLE MATERIAL

Some projects have a material requirement for the maximum allowable thermal resistance, measured in mK/W. Other projects state a minimum thermal conductivity level, expressed in W/mK. We therefore give both values in our product data sheets, so you can quickly see which product meets your needs.
