This document, which is a Technical Report, provides recommendations for the selection and testing where necessary of conductor stringing equipment and accessory items used for the installation of bare and insulated overhead distribution conductors, bare overhead transmission conductors and overhead earth wires.
Procedures are recommended for proper earthing in order to protect equipment, components and personnel from currents which can result from accidental contact with nearby energized conductors or from the induced or fault currents which can result in some circumstances.
The items of equipment under consideration in this document are used for transmission and distribution systems.
