IEC 60228:2023 specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors. This document does not apply to conductors for telecommunication purposes. The applicability of this document to a particular type of cable is as specified in the standard for the type of cable. Unless specified otherwise in a particular clause, IEC 60028 ED4 relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable. Conductors described in this document are specified in metric sizes. Informative annexes provide supplementary information covering temperature correction factors for resistance measurement (Annex B) and guidance on dimensional limits of circular conductors (Annex C). This document has the status of a horizontal publication in accordance with IEC Guide 108.

Flat flexible cables

SIST EN 50214:2024

This document covers the construction, requirements and particular test methods for flat, flexible PVC or halogen-free insulated and sheathed cables, of rated voltage Uo/U 300/500 V and above 1 mm2, Uo/U 450/750 V for use in passenger and goods lifts (elevators), and Uo/U 450/750 V for general purposes and for special applications such as hoists and travelling cranes. NOTE 1 This revision is in accordance with an agreement with CEN TC 10 to specify in the same standard a) flexible cables for lifts as required by EN 81-series, and b) flexible cable for applications such as hoists and travelling cranes, previously found in HD 359. In accordance with this agreement, only those cables in Clauses 5 and 6 are suitable for use with EN 81-series. NOTE 2 The limits for the overall diameter of the cables have been calculated in accordance with EN 60719.

HD 629.2 S3:2024(Main)

Test requirements for accessories for use on power cables of rated voltage from 3,6/6(7,2) kV up to 20,8/36(42) kV - Part 2: Cables with impregnated paper insulation

SIST HD 629.2 S3:2024

1.1 General This document specifies performance requirements for type tests for cable accessories for use on impregnated paper insulated power cables as specified in HD 621. It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process, which might affect the performance characteristics. Accessories for special applications such as submarine cables, ships cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions) are not included. Test methods are included in EN 61442:2005. NOTE It might be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonstrate that conformity to the earlier standard can be used to claim conformity to this document, provided an assessment is made of any additional type testing that might need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done separately. 1.2 Type of accessories The accessories covered by this document are listed below: - indoor and outdoor terminations of all designs, including terminal boxes; - straight joints, branch joints and stop end joints of all designs, suitable for use underground or in air; - screened or unscreened plug-in type or bolted-type separable connectors capable of interfacing with bushing profiles as specified in EN 50180 series and EN 50181. 1.3 Rated voltage The rated voltages U0/U(Um) of the accessories covered by this document are 3,6/6(7,2) - 3,8/6,6(7,2) - 6/10(12) - 6,35/11(12) - 8,7/15(17,5) - 12/20(24) - 12,7/22(24) - 18/30(36) - 19/33(36) - 20,8/36(42) kV.

HD 629.3 S1:2024(Main)

Test requirements for accessories for use on power cables of rated voltage from 3,6/6(7,2) kV up to 20,8/36(42) kV - Part 3: Transition joints between cables with impregnated paper insulation and cables with extruded insulation

SIST HD 629.3 S1:2024

1.1 General This document specifies performance requirements for type tests for transition joints for use between extruded insulated power cables as specified in HD 620 and impregnated paper insulated power cables as specified in HD 621 or another relevant standard. Once type test for an accessory is successfully completed, it is not necessary to repeat the test, unless changes are made in the materials, design or manufacturing process, which might affect the performance characteristics. Possible extra thermo-mechanical forces due to high current loads from renewable sources of power generation are not covered by these tests (under consideration). Accessories for special applications such as submarine cables, ships cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions) are not included. Test methods are included in EN IEC 61442:- and Annex E. NOTE 1 This document does not invalidate existing approvals of products achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. However, products approved according to such national standards or specifications cannot directly claim approval to this document. NOTE 2 It might be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonstrate that conformity to the earlier standard can be used to claim conformity to this document, provided an assessment is made of any additional type testing that might need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done separately. 1.2 Type of accessories The accessories covered by this document are straight and branch transition joints of all designs, suitable for use underground or in air. 1.3 Rated voltage The rated voltages U0/U (Um) of the accessories covered by this document are 3,6/6(7,2) - 3,8/6,6(7,2) - 6/10(12) - 6,35/11(12) - 8,7/15(17,5) - 12/20(24) - 12,7/22(24) - 18/30(36) - 19/33(36) - 20,8/36(42) kV.
