HD 620 S3:2023
(Main)Distribution cables with extruded insulation for rated voltages from 3,6/6 (7,2) kV up to and including 20,8/36 (42) kV
Distribution cables with extruded insulation for rated voltages from 3,6/6 (7,2) kV up to and including 20,8/36 (42) kV
HD 620 applies to cables with extruded insulation and for rated voltages Uo/U(Um) from 3,6/6 (7,2) kV up to 20,8/36(42) kV used in power distribution systems of voltages not exceeding the maximum r.m.s. value of the system voltage Um. This Part (Part 1) specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD. Test methods specified are given EN 60228, EN 60229, EN 60332-1-2, EN 60811, EN 60885-3, HD 605 and HD 632. Attention should be drawn to the fact that a significant number of sections include references to long term tests which are collected in HD 605. These long-term tests are considered as necessary and reflect the best available knowledge for the existing cable design. They are related to specific designs and different philosophies concerning adequate measures against the influence of water. However, it is the firm intention to reduce this large number of different tests, but more experience should be gained before starting to rationalise this important matter. The particular types of cables are specified in Parts 9 to 12. NOTE Parts 3, 4, 5, 6, 7 and 8 were withdrawn in HD 620 S2.
Energieverteilungskabel mit extrudierter Isolierung für Nennspannungen von 3,6/6 (7,2) kV bis einschließlich 20,8/36 (42) kV
Câbles de distribution, à isolation extrudée, pour des tensions assignées de 3,6/6 (7,2) kV à 20,8/36 (42) kV inclus
Distribucijski kabli z ekstrudirano izolacijo za naznačene napetosti od 3,6/6 (7,2) kV do vključno 20,8/36 (42) kV
Standard HD 620 se uporablja za kable z ekstrudirano izolacijo in za nazivne napetosti Uo/U(Um) od 3,6/6 (7,2) kV do 20,8/36(42) kV, ki se uporabljajo v sistemih za distribucijo električne energije z napetostjo, ko ta ne presega najvišje efektivne vrednosti pri izmeničnem toku sistemske napetosti Um.
Ta del (1. del) določa splošne zahteve, ki veljajo za te kable, razen če je v določenih razdelkih tega standarda HD določeno drugače.
Določene preskusne metode so navedene v standardih EN 60228, EN 60229, EN 60332-1-2, EN 60811, EN 60885-3, HD 605 in HD 632.
Upoštevati je treba tudi dejstvo, da veliko število razdelkov vključuje reference na dolgoročne preskuse, ki so zbrani v standardu HD 605. Ti dolgoročni preskusi veljajo za nujne in odražajo najboljše razpoložljivo znanje za obstoječo zasnovo kablov. Nanašajo se na posebne zasnove in drugačne pristope v zvezi z ustreznimi ukrepi za zaščito pred vplivi vode. Vseeno pa je pri tem jasen namen zmanjšati to veliko število različnih preskusov, vendar je pred začetkom postopka racionalizacije tega pomembnega vprašanja treba pridobiti več izkušenj.
Posebne vrste kablov so podane v delih od 9 in 12.
OPOMBA: Deli 3, 4, 5, 6, 7 in 8 so bili umaknjeni iz standarda HD 620 S2.
