Hanson UK has launched a new high-performance concrete that is ideal for use by the power sector.
Powercrete was developed by HeidelbergCement, Hanson’s parent company, and is a heat conducting concrete. It helps to dissipate the heat generate by high-voltage and ultra-high voltage electrical cables with the same ease of placement as normal concrete.
The high thermal conductivity of the product enables it to be used as a bedding and infill material for underground high-voltage and ultra high-voltage cabling, helping to minimise transmission loss.
Powercrete is the only product of its type available in the UK. Its first application was at Iver, Buckinghamshire, where 217 m3 was used to encase the 175 kilovolt cables that send power to Heathrow Airport
