CAN/ULC-61911-05

1 Scope The present 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. 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 induced voltage from adjacent energized lines, lightning strikes, switching errors or electrostatic charging. The equipment under consideration in this Technical Report is used for distribution voltages, usually considered to be below 50 kV. However, for voltages of 50 kV and above, use of IEC 61328 may be more appropriate. The choice of whether IEC 61328 or this Technical Report applies to the work being considered will usually depend on the physical size of the conductors, the size of the structures and the average span between supports.
