PowerSand CBS
PowerSand CBS
Cement-bound sand backfill materials designed for underground high-voltage cable installations.
Application
Used as backfill in the installation of underground electricity cables.
Description
Cement-bound sand stabilised backfill materials as defined in ENA TS 97-1 for underground electricity cable installations.
Available in two variants:
- PowerSand CBS: backfill material designed for underground high-voltage cable installations. It offers excellent thermal conductivity, compacts easily around cables, and helps dissipate heat to reduce electrical resistance.
- PowerSand CBS Extra: high-performance, non-traditional stabilised backfill designed for power cable installations. It offers lower thermal resistivity than traditional CBS and contributes to a reduced carbon footprint.
Features and benefits:
- Keeps cables cool due to low thermal resistance.
- Consistent for ease of use and ultimate performance.
- UKAS test certificates available if requested.
- Meets or exceeds the requirements of ENA TS 97-1.
