Thorne & Derrick also supply the full range of cable duct including ducting for low voltage street lighting and motorway communications applications.
Selecting Cable Duct
When selecting a cable duct, the fill ratio (defined as the ratio of the cross-sectional area of the intended cable and the internal cross-sectional area of the duct) should be considered when determining the size of cable duct suitable for a cable protection application. The fill ratio should not normally exceed 65%.
The following cable duct classifications are according to ENATS 12-24 (2014):
- Class 1 Cable Ducts – to give 450 N compression strength at 75 °C
- Class 2 Cable Ducts – to give 450 N compression strength at 50 °C
- Class 3 Cable Ducts – to give 450 N compression strength at 23 °C
