“本加拿大国家标准提供了用于安装裸露和绝缘架空配电导线的导线架线设备和附件的选择和测试建议。建议适当接地的程序,以保护设备、部件和人员免受意外接触可能产生的电流影响。”ith附近的带电导体,或相邻带电线路的感应电压、雷击、开关错误或静电充电。本加拿大国家标准中考虑的设备用于配电电压,通常被认为低于50 kV。然而,对于50 kV及以上的电压,使用标准CAN/ULC-61328-05可能更合适。选择标准CAN/ULC-61328-05或加拿大国家标准是否适用于正在考虑的工程通常取决于导线的物理尺寸、结构尺寸和支架之间的平均跨度。 "
"This National Standard of Canada 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 National Standard of Canada is used for distribution voltages, usually considered to be below 50 kV.However for voltages of 50 kV and above, use of Standard CAN/ULC-61328-05 may be more appropriate. The choice of whether Standard CAN/ULC-61328-05 or this National Standard of Canada 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."
