Cable Jointer
Summary
Cable jointers make and repair joins in insulated power supply and control cables installed in underground pipes, trenches and overhead systems. They also prepare cable terminations for electrical equipment and overhead lines.
Cable jointers also install and maintain underground electrical cables used to transmit and distribute electricity in city and country areas, new housing estates and industrial centres.
Duties & Tasks
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

- encase cables in protective covers
- work with other staff to install or replace cables.
Working Conditions
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.
