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 1: Accessories for cables with extruded insulation

Alkalmazási terület

1.1 General This document specifies performance requirements for type tests for cable accessories for use on extruded insulation power cables as specified in HD 620 or other relevant cable standards. 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, ship cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions) are not included. Test methods are included in EN 61442:2005. NOTE 1: This European Standard 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 European standard. NOTE 2: It may 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 European Standard, provided an assessment is made of any additional type testing that may 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 standard are listed below: a) indoor and outdoor terminations of all designs, including terminal boxes; b) straight-joints, branch-joints, stop ends and loop joints of all designs, suitable for use underground, indoors or outdoors; NOTE 1 Tests specific for UV and outdoor weather resistance are not included. c) screened or unscreened plug-in type or bolted-type separable connectors, capable of interfacing with bushing profiles as specified in EN 50180 and EN 50181. NOTE 2 Joints connecting extruded insulation cables (HD 620) to paper insulated cables (HD 621) are not included. The requirements for these accessories are dealt with in HD 629.2. 1.3 Rated voltage The rated voltages U0/U (Um) of the accessories covered by this standard 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 where: U0 is the rated power-frequency voltage between conductor and earth or metallic screen, for which the cable accessory is designed; U is the rated power-frequency voltage between conductors for which the cable accessory is designed; Um is the maximum value of the 'highest system voltage' for which the cable accessory is designed. 1.4 Current The continuous current rating of a termination or joint for extruded insulation power cables is in accordance with the appropriate cable specified in HD 620 or other relevant cable standards and is suitable for operation at the rated current and under short circuit fault conditions at the temperatures stated therein. The current rating of a separable connector is governed by the current rating of the mating bushing (see EN 50180 and EN 50181).
