This Handbook gives an insight into the construction and usage of telecommunication cables. Telecommunication cables represent a large investment and provide a vital link in transmitting information. Accordingly, they must be designed to provide a consistent, reliable electrical path while resisting mechanical and environmental conditions imposed during their installation and service life. Good quality materials need to be selected and arranged to meet local conditions and cost objectives.

Basic materials to be used for the construction of telecommunication cables

Cables are composed of a number of different but compatible materials. Conductors are normally made of copper. Insulating materials consist of paper, pulp, polyvinyl chloride (PVC), polyethylene, or polypropylene. Cable sheaths are available with lead, plastic, copper, aluminium, steel and additional preservative compounds applied when required.
