Specifies the construction, dimensions and test requirements of power cables with extruded solid insulation from 6 kV up to 30 kV for fixed installations such as distribution networks or industrial installations.
When determining applications, it is recommended that the possible risk of radial water ingress is considered. Cable designs with barriers claimed to prevent longitudinal water penetration and an associated test are included in this part of IEC 60502.
Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area) nor for submarine use or shipboard application.
Significant technical changes with respect to the first edition have been made. The changes relate to possible water ingress, large conductor sizes, partial discharge requirements, insulation and oversheath thickness requirements, range of type approval, electrical tests after installation and tabulated current ratings.
