Cable Jointer

State/Territory Specific Information

Cable jointers make and repair joins in insulated power supply and control cables installed in underground pipes, trenches, and/or overhead systems. They also prepare cable terminations for electrical equipment and overhead lines.

Cable jointers may perform the following tasks:

  • pull electrical cables through underground pipes (or conduits) and join cables in transmission and distribution systems
  • prepare low- and high-voltage cable joints and cable terminations while connecting and installing electrical equipment and overhead lines
  • test and locate cable faults, and maintain and repair cables
  • update location diagrams for the layout of cable systems
  • make sure that conductors are correctly connected between sub-stations and customers' premises when installing and making repairs
  • assist in manufacturing and preparing cable jointing components
  • dig trenches and service pits or tunnels
  • encase cables in protective covers
  • work with other staff in installing or replacing cables.

Cable jointers mainly work outdoors, sometimes in cramped and confined conditions or at heights. They often work in sub-stations, which reduce high-voltage electricity to lower levels for consumer use. They need to maintain good relations with property owners, tenants and authorities. Cable jointers often work as part of a team.
