Installing Cable Duct

Cables should be installed into ducts that are sized suitable to accommodate the cable diameters and before a cable is installed all cable duct should be checked and cleared of obstructions. To ensure that the duct is suitable for the type of cable to be installed UKPN (UK Power Networks, a UK DNO) recommend a 3 metre length of the LV-HV cable to be installed shall be pulled through the complete length of the cable duct. The duct should then be examined for damage before proceeding to pull and install the complete cable length.

If the sample of cable is found to have deep scores and tears in its cable outer sheath, which are more than half the thickness of the outer sheath, the cable duct route shall be repaired before any attempt is made to install the final length of cable.
