High voltage direct current (HVDC) power transmission - Cables with extruded insulation and their accessories for rated voltages up to 320 kV for land applications - Test methods and requirements

IEC 62895:2017 specifies test methods and requirements for transmission power cable systems, cables with extruded insulation and their accessories for fixed land installations, for rated voltages up to and including 320 kV.

Within the scope of this standard “extruded insulation” means insulation manufactured by extrusion of either thermoplastic (e.g. polyethylene) or crosslinked (e.g. crosslinked polyethylene, ethylene propylene rubber, etc.) material. The insulation material may be either unfilled or filled (e.g. with mineral or carbon).

The requirements apply to single-core cables in combination with their accessories, outdoor and terminations for gas insulated systems, joints, and asymmetric joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables, for which modifications to the standard tests may be necessary or special test conditions may need to be devised.
