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
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.

Exigences relatives aux essais des accessoires des câbles d'énergie pour des tensions assignées de 3,6/6(7,2) kV à 20,8/36(42) kV - Partie 3: Jonctions mixtes entre les câbles isolés au papier imprégné et les câbles à isolation extrudée
Preskusne zahteve za pribor, ki se uporablja na elektroenergetskih kablih z naznačeno napetostjo od 3,6/6(7,2) kV do vključno 20,8/36(42) kV - 3. del: Prehodne spojke med kabli z impregnirano papirno izolacijo in kabli z ekstrudirano izolacijo
Ta dokument določa zahteve glede delovanja za tipske preskuse za prehodne spojke, ki se uporabljajo na elektroenergetskih kablih z ekstrudirano izolacijo, kot je opredeljeno v standardu HD 620, ali kablih, izoliranih z impregniranim papirjem, kot je določeno v standardu HD 621 ali drugem zadevnem standardu.
Ko je tipski test pribora enkrat uspešno opravljen, ga ni treba ponavljati, razen če
je prišlo do sprememb v materialih, zasnovi ali proizvodnem procesu, ki lahko vplivajo na lastnosti delovanja.
V teh preskusih niso zajete morebitne termo-mehanske sile zaradi visokih tokovnih obremenitev obnovljivih virov proizvodnje
električne energije (v obravnavi).
Pribor, namenjen posebni uporabi, na primer podmorski kabli, ladijski kabli ali uporabi v nevarnih razmerah (v eksplozivnih okoljih, ognjeodpornih kablih ali potresnih okoljih), ni vključen.
Te metode so vključene v standardu EN IEC 61442: – in dodatku E.
OPOMBA 1: Ta dokument ne izniči obstoječih odobritev izdelkov, prejetih na podlagi nacionalnih standardov in specifikacij in/ali prikazu zadovoljivega delovanja. Vendar se izdelki, odobreni na podlagi omenjenih nacionalnih standardov ali specifikacij, ne morejo neposredno sklicevati na odobritev tega dokumenta.
OPOMBA 2: Odvisno od dogovora med dobaviteljem in kupcem in/ali ustreznim telesom za ocenjevanje skladnosti je mogoče prikazati, da se lahko skladnost s prejšnjimi standardi uporabi za sklicevanje na skladnost s tem dokumentom, če se predhodno oceni, ali je treba izvesti dodatne tipske preskuse. Dodatnih preskusov, ki so del zaporedja preskusov, ni mogoče izvesti posebej.
