We supply Cement Bound Sand throughout Somerset and into parts of Devon, Dorset, Wiltshire & South Gloucestershire
We have supplied many projects ranging from Solar Farms to the National Grid 400kV cabling over the Mendips
CBS also known as Stabilised Sand and is mainly used for cable installations where a hardened fill for protecting the cable is required with a given low thermal resistivity
Our CBS is compliant with Energy Network Association Technical Specification (ENA TS) 97-1 and National Grid Technical Specification (NGTS) 3.05.07. Certificates are available on request.
Compliant CBS is used to ensure that a low thermal resistance is given and as a result the material can conduct heat away from the cables that is produced during electricity transmission. The thermal conductivity around the cables is of a known value and will remain consistent for the length of the cable being installed. This allows the cable the ability to carry the required current and be maintained at the designed capacity.
Can you use any 14:1 sand cement mix?
No, as not all materials have the required thermal conductivity. Our CBS is fully compliant so you can order with confidence
