Železniške naprave - Stabilne naprave električne vleke - Posebne zahteve za kompozitne izolatorje za vozne vode omrežij

Ta mednarodni standard določa značilnosti kompozitnih izolatorjev sistemov kontaktnega vodnika za nadzemno električno vleko pri železnicah, kot je opredeljeno v standardu IEC 60913. Izolatorji, določeni v tem standardu, se uporabljajo pri napajalnih napetostih električne vleke z nazivno napetostjo več kot 1000 V pri izmeničnem toku ali z nazivno napetostjo več kot 1500 V pri enosmernem toku. Posebni načini uporabe, kjer lahko pride do visokih vrtilnih obremenitev, niso zajeti v tem standardu; dobavitelj in odjemalec se dogovorita o posameznih preskusih glede predstavitve ureditev s kritično obremenitvijo.
Ta mednarodni standard se uporablja za kompozitne izolatorje, kot je opredeljeno v spodnji točki 3.1, in ne za druge polimerne izolatorje.
Določbe v tem standardu so namenjene za zasnovo in izdelavo novih sistemov kontaktnega vodnika za nadzemno električno vleko z izolatorji ali za popolno obnovo obstoječih voznih vodov omrežij.
Ta standard podaja za kupca in proizvajalca številne preskuse, ki se uporabljajo za ocenjevanje primernosti izolatorjev za dano železniško okolje. Odjemalec lahko določi dodatne preskuse za izmero skladnosti izolatorja v določenih pogojih delovanja.
Standard določa karakteristike izdelka, preskusne metode in prevzemne kriterije. Cilj tega standarda je določiti določbe za zasnovo in zagotavljanje storitve, ki jih proizvajalec navede za kupca za namene uporabe v železniški infrastrukturi.
