Scope
This part of GB/T 12706 specifies the requirements for distribution networks or industrial installations. Construction of extruded insulated power cables for fixed installations with rated voltages from 6 kV to 30 kV; dimensions and test requirements. When deciding on the cable application, it is recommended to consider the possible risk of radial water ingress. This standard covers so-called longitudinal water-blocking structural cables and their tests. This section does not cover cables for special installation and operating conditions, such as overhead cables, mining industry, nuclear power plants (in and near containment), and cables for underwater or ship use.
