ThermalRite Thermal Sand is now widely used when installing underground cables to improve performance. Our materials satisfy the thermal and mechanical requirements stipulated by Engineers for encapsulating the cable pipes, and are rated and tested to ensure the heat generated by the cable is transferred through the thermal sand to the surrounding earth to reduce resistive losses better than other backfill.

Our Thermal Sand has been approved by the labs that test materials for PECO, PSE&G, Con Ed and Atlantic City Electric.
