Technical cable jointer


What they do

Cable jointers lay, joint, terminate and repair underground power cable. Cable jointers lay new power cables through underground pipes and terminate them at electrical equipment. They also conduct tests to check cable integrity and locate faults.

Working conditions

Cable jointers work outdoors in most weather conditions, and may be in confined spaces. In order to minimise the risks associated with working with high-voltage electricity, they must follow strict safety requirements. They may also be expected to be on call to respond to emergencies that occur outside of regular hours.

Cable jointers can be employed by government owned electricity network operates, by specialised cable jointing companies, by electrical contractors or by large companies who operate their own private electricity network.

Tools and technologies

Cable jointers lay insulated power cables and use specialised tools and electrical equipment to joint and terminate these cables. They also use electrical instruments, such as multimeters, insulation resistance testers and specialised instruments to assess the cables integrity and whether it is performing appropriately.

Safety is a key concern when working with power cables, so cable jointers must wear protective clothing including, protective clothing, safety footwear, safety glasses and for some tasks they must wear specialised personal protective equipment.
