Cable Rollers For Straight Horizontal Cable Runs In Underground Cable Trenches

By Chris Dodds on 11th November, 2013

LV-HV power cables should be supported on straight cable rollers which have no sharp edges to damage cable sheathing under tension when being pulled into the cable trench.

The cable roller must be placed directly into the open cable trench to prevent the LV-HV power cable from dragging on the bottom of the trench.

Cable roller spacing is dependent upon cable type and cable pulling tension along the route. Prior to the cable being laid onto the straight cable roller it is advised to use leading cable rollers to support the actual cable over the entire cable drum width.

During preparation of the cable trench, the trench bottom should be as level as possible and any gradient changes should be made as gradual as site conditions permit.

The cable trench bottom must be free of stones and the edges of the trench shall be cleared of any stones, tools or objects which may fall into the trench and damage the cable.
