Superior Heat Dissipation

LG Sands’ high-purity silica sand has a low thermal resistivity (0.8-1.0 Km/W), ensuring efficient heat dissipation and preventing underground cable overheating in solar farm trenches.

Cable Efficiency & Longevity

By reducing thermal buiVld-up, thermal sand improves electrical transmission efficiency, extends cable lifespan and minimises maintenance costs over time.

Proven Performance

In large-scale solar farm projects, the use of thermal sand has significantly improved project results, extended cable lifespan and provided long-term cost savings.

Scalable Supply

Thermal sand offers scalability and long-term availability, making it a dependable choice for large-scale solar farm developments and other infrastructure projects.

Challenge

After facing challenges with a lower-grade product, the client brought us onboard to provide a proven, high-quality thermal sand solution to keep the project on schedule. They needed a reliable product with consistent thermal properties that could be delivered quickly and efficiently.

Solution

LG Sands provided 50,000 tonnes of premium thermal sand to ensure superior heat dissipation and long-term performance in solar farm cable trenches. Our precisely graded silica sand met the project’s strict thermal resistivity requirements.

Result

Our highly consistent product quality not only met but exceeded expectations, with all thermal resistivity results falling within the optimal range of 0.8–1.0 Km/W. This improved cable efficiency and allowed the contractor to earn a performance bonus from their client due to the enhanced energy transmission and long-term cost savings.

Industries We Serve

With a proven history of supplying tens of thousands of tonnes of premium thermal sand to solar farms and infrastructure projects, LG Sands delivers reliable, high-performance solutions for even the most demanding project requirements.

Our consistent thermal properties ensure optimal heat dissipation, improving energy efficiency and cable longevity. Backed by a secure, large-scale supply, we are equipped to support projects of any size, ensuring on-time delivery, superior performance and long-term cost savings.
