IEC 63026:2019

Submarine power cables with extruded insulation and their accessories for rated voltages from 6 kV (<em>U</em>_m = 7,2 kV) up to 60 kV (<em>U</em>_m = 72,5 kV) - Test methods and requirements

IEC 63026:2019 specifies test methods and requirements for power cable systems, cables with extruded insulation and their accessories for fixed submarine installations, for rated voltages from 6 kV (Um = 7,2 kV) up to 60 kV (Um = 72,5 kV).
This document includes the electrical tests and the physical tests on materials and components as well as the specific mechanical tests that are applicable to submarine cable systems.
The requirements apply to armoured single-core cables and three-core cables in combination with their accessories, terminations and joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables for dynamic applications (i.e. for direct connection to a floating structure), for which modifications to the standard tests can be necessary or special test conditions be devised.
This document is applicable to submarine cables installed in permanently submerged conditions with water depths up to 250 m.
This document does not include accessories having a mechanical function only, such as hang-offs or armour clamps.
