THERMAL SAND SUPPLY

What is Thermal Sand?

Thermal Sand is an insulative form of sand widely used throughout the power industry to improve underground electrical performance. Electrical cables are typically thought of as a conductor which is limited by the temperature in which insulation materials can withstand. As more power is drawn through the cables, more heat is generated and more insulation is required.

While a multitude of thermal insulators exist, thermal sand is amongst the most efficient, being popularised by the power industry during the installation of underground cables. Thermal sand is rated and tested to provide proven heat transfer, allowing cables to operate at optimal levels.

If you are seeking to improve your underground electrical cable performance, thermal sand may be the best alternative. To order premium thermal sand, you can contact us directly on 1300 291 130.

How does Thermal Sand work?

Thermal sand works by minimising excess temperature which is an attribute given by its low thermal reactivity. A material that is not very thermally reactive has a tendency to not heat up anywhere near as much as most other insulators when the cables are under high loads. Thermal Sand essentially becomes the connection between the cables and other general mass. All heat generated by underground power cables must be effectively transferred, dissipate, or dispersed through its insulators, which is why thermal sand has become increasingly popular.


Thermal Sands ability to manage heat transfer allows operating cables to remain cool and prevents overheating which may otherwise lead to permanent damage. Improving the underground thermal environment through insulators such as thermal sand can commonly lead to an increase in cable amp capacity and overall efficiency - making it a leading choice within the industry.


For you, thermal sand essentially means more constant power and a longer cable life.
