The Power to Connect

Radius CTS offer integrated underground cable ducting systems for the protection of cables in power networks and renewable energy projects. Our solutions are developed to meet or exceed the requirements of Distribution Network Operators (DNOs) and industry standards and are designed and manufactured around safety, quality and reliability.

We have electrical cable ducting solutions for High Voltage (HV), Medium Voltage (MV) and Low Voltage (LV) applications with cables operating at 11kV, 33kV, 66kV and EHV up to 132kV. Our range covers the complete ENA TS 12-24 spectrum Class 1, Class 1+, Class 2 to Class 3.

Our electrical ducting includes duct and fittings for solid wall PE100, uPVC with sealed and conductive options, twinwall HDPE and service ducts, all of which are available in a range of sizes and SDRs. This is complemented by our Access Chambers, the Openreach approved QuadBox®, our brand new RadBox2® and the RadBox®, ideally suited to telecoms applications.

Radius electric cable duct can be installed by both Direct Bury and No Dig (trenchess) methods such as horizontal directional drilling (HDD). Check out our specialist HDD PE100 Beadless ducting which guarantees smooth internal welding for easy cable pulls.
