Basic Information
Scope
This part of GB/T 12706 specifies the structure, dimensions, and test requirements of extruded insulated power cables with a rated voltage of 6 kV to 30 kV.
This part applies to fixed-installation extruded insulated power cables with a rated voltage of 6 kV to 30 kV in distribution networks or industrial installations. It also applies to cables with a longitudinal waterproof structure and their tests. When determining the application of cables, it is advisable to consider the possible risk of radial water ingress.
This part does not apply to cables subject to special installation and operating conditions, such as overhead cables, mining industries, nuclear power plants (inside and near the safety shell), and underwater or shipboard cables.
