Thermocrete Underground Cable Thermal Backfill
When you are deep in the trench – we have got it covered!
Heat Conducting Concrete Solutions
The use of underground cables has increasingly become the preferred choice when compared with the visual impact of pylons and overhead lines. However, when power cables are buried in the ground the high voltages generate a large amount of heat which result in performance reductions and expensive maintenance interventions.
A robust heat dissipation solution is required to prevent cable overheating and subsequent reduction in its capacity for carrying electrical current. CEMEX provide a range of heat conducting concrete solutions, suitable for all underground cable applications and have been successfully installed in a wide range of projects around the UK.
Thermocrete 14:1 is our cement bound sand (CBS) product which is used as a bedding and backfill material for underground LV and HV cables. Thermocrete 14:1 has a low thermal resistance and as a result the material can conduct heat, away from the cables that is produced during electricity transmission.
With all the benefits of Thermosand and an improved thermal performance, the product is ideal for applications where extra stability is required. Due to it’s composition Thermocrete can also be removed relatively easily if required. The product is designed to meet the requirements of the industry requirements including ENA TS 97- 1 and NGTS 3.05.07.
Thermocrete Ultra is our high performance specialist thermal conducting concrete which is used as a bedding and backfill material for underground HV and UHV cables. Thermocrete Ultra has a very low thermal resistance and as a result the material can conduct significant amounts of heat, away from the cables, produced during electricity transmission.
Designed specifically to meet your specification requirements Thermocrete Ultra can be supplied in a range of consistencies and compressive strengths.
