Road and Rail Excavations are highly skilled and equipped to install all types of cabling for various utilities. As a business, we have over 100 years of combined experience in high voltage and low voltage cable installation in Australia cross pollinating into the Telecommunications and Rail sectors.

Each cable installation is extremely well planned through the following process:

  • Size and length of cable to be installed

  • Manufacturers specifications, particularly maximum installation tensions and bending radius

  • A full, calculated assessment of the proposed installation route which includes bend radius/numbers (open or in conduit), inclines and coefficient of friction factoring to identify installation tension

  • Validation that the planned cable installation does not void manufacturers cable specifications

Should the calculated assessment be greater than the acceptable limits of the selected cable nominated, Road and Rail Excavations will engineer solutions to enable installation within acceptable limits. Some of these solutions may include installing strategically located cable pushers or cat holes for caterpillars. In addition, we can CCTV each conduit to prove integrity at the client’s request.

During the installation of each cable at the worksite, we have state of the art equipment to monitor and record installation tensions to ensure that every cable is installed within designed limits and recorded as part of our quality management system.

Our specialised cable pulling equipment includes various sized cable hauling winches, cable trailers, drum stands, cable rollers and guides to adapt to each cable installation plan. We have the capability to handle cable drums of any size dimension and weight up to 45 ton. Our cable installation methodologies can be applied to install cables ranging from telecommunications, fibre optic, low voltage and high voltage cabling up to 330kV. Further, we can install single core, multicore and cables in trefoil formation in open trenches, conduits and in hazardous environments (substation situations).

We specialise in complex cable installations such as through Sydney’s CBD pit network. We have the expertise to design complex rigging systems to ensure the integrity of existing, in service cables remains intact whilst working in these high risk environments.

Road and Rail Excavations are cable installation experts, with a diverse and intimate knowledge of how to install cables. All cables are installed to our Quality Management System, ensuring that they are installed, sealed and labelled to the highest of standards.
