Line Installers and Cable Splicers Job Overview


During the installation of new telecommunication lines and power lines, workers use motorized machinery to dig holes first and erect the poles or towers used to support the cables. (In some areas the lines must be buried underground, and in these cases installers use motorized equipment to dig and lay the cables in the underground pipes.) These line technicians, also called external plant technicians and construction line workers, they climb the poles. using metal steps (or use truck-mounted work platforms) and install the necessary equipment and cables. After building the infrastructure, the linesmen connect the cable along towers and poles or undergrounds through tunnels and trenches. In some cases, installers need to connect other cables to the customer's premises to connect to the external line.

Installers who work with telecommunication lines generally leave the ends of the cables free to allow splicers to connect later; Installers who work with power lines generally connect the cables themselves. To work on power lines, the insulators must be placed on the poles before connecting the cables. To join the sections of the power line and guide the transformers and electrical accessories, the line installers connect, weld and insulate the conductors and related wiring. In some cases, line installers need to connect other equipment, such as transformers, circuit breakers and lightning protection devices, to the line poles.

After the line installers have completed the installation of underground pipes or poles, wires and cables, the cable joints complete the line connections; They also rearrange cables when changing lines. To join the individual cables within the cable, the joints must cut the cable sheath and the cable insulation. They then gradually test or eliminate each conductor to identify the corresponding conductors in adjacent cable sections based on wiring diagrams and specifications. At each joint, they wrap the insulation around the wires and seal the joint with a lead sheath or cover the joint with another type of closure. Sometimes they fill the coating with pressurized air so that leaks can be located and repaired.
