Cable Trenching & Ducting
The cable corridors that tie a site together and connect it to the grid — HV and LV ducting, draw pits and joint bays, open-cut or plough-trenched to suit the ground.

Get in TouchCable infrastructure is what connects a renewable site together and ties it into the grid. It runs the length and breadth of a development, so getting it installed efficiently and to standard matters to the whole programme.
HWBC self-delivers the full cable-civils scope — trenching, ducting, draw pits, joint bays and reinstatement — choosing open-cut or plough trenching to suit the ground and the route.
Open-cut and plough trenching for high and low voltage cable routes, sized and graded to the design.
Installation of duct runs and cable corridors that link arrays, inverters, substations and the grid connection.
Draw pits, joint bays and access chambers built into the route for pulling and jointing cable.
Protective bedding and surround to specification, with marker tape and tile where required.
Ducted crossings beneath access roads and trackways, coordinated with the roads works.
Compacted backfill and full reinstatement of the ground surface along the route.
Across a recent 29MW solar scheme, HWBC self-delivered the cable-civils package — over 12 km of trenching carrying MV and LV cable, with manholes, fibre ducting and multiple road crossings, all reinstated to standard.
The figures stay on the project page; here they stand as proof of the scale HWBC delivers.

Set out the route and excavate or plough to the required depth and grade.
Install ducting, draw pits and bedding, ready for cable pulling and jointing.
Backfill, compact and reinstate the surface, leaving the route clean.
