Thermal Grout is a cement-based, pumpable fill material designed and tested to achieve low thermal resistivity for electrical transmission infrastructure. Thermal grouts are used to infill annular space between liners that carry electrical transmission cables. Heat generated by transmission cables under load needs to be efficiently transferred to surrounding ground to control cable temperatures and extend life of cables contained within underground carrier systems.
