HD 632 S2:2008

This standard specifies test requirements for power cables with extruded insulation, of the types listed in Table 1, and their accessories, of rated voltage, U, above 36 kV (Um = 42 kV) up to and including 150 kV (Um = 170 kV), for fixed installations intended for transmission and distribution systems, and for use in power generating plants and sub-stations. Depending on the design and the system conditions, additional or even fewer tests or other requirements which are not described in the Part 1 can be specified in the particular sections of Parts 3 to 11. In these parts each section is either: 1) A full tabulation showing how the particular section either agrees, or deviates from, each clause of Part 1; or 2) A reduced tabulation showing only those places where the particular section deviates from Part 1. The requirements apply to single-core cables and three-core cables with separate cores and to their accessories for usual conditions of installation and operation, but not to special cables and their accessories, such as those designed for submarine cables, for which modification to the standard tests may be necessary or special test conditions may need to be devised. This standard does not cover transition joints between cables with extruded insulation and paper insulated cables.
