ThermalRite Sand improves the external thermal environment and accurately defines the soil and backfill thermal rho. This results in a 10% to 15% increase in cable amp capacity, with 30% improvements noted in some cases.
DunRite materials satisfy the thermal and mechanical requirements stipulated by AECOM 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. On projects where access is needed on a continuing basis, material can be dug out by hand to continue on with the next day’s work.
ThermalRite Sand has been approved by the labs that test materials for PECO, PSE&G, Con Ed and Atlantic City Electric.
