加拿大国家标准提供了架空导线和架空地线安装所需的导线架线设备和附件的选择和测试建议。建议采用适当接地的程序，以保护设备、部件和人员免受可能导致某些情况的感应或故障电流的影响。本加拿大国家标准中考虑的设备用于传输电压，通常被认为是100 kV及以上，但可能低至60 kV。所述的许多要求和试验也适用于小于100 kV的配电系统中使用的设备。

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 overhead conductors and overhead earthwires.Procedures are recommended for proper earthing in order to protect equipment, components and personnel from the induced or fault currents which can result in some circumstances.The equipment under consideration in this National Standard of Canada is used for transmission voltages which are usually considered to be 100 kV and above, but may be as low as 60 kV. Many of the requirements and tests stated apply also to equipment used in distribution systems with less than 100 kV.
