Aeronavtika - Kabli, električni, za splošne namene, z vodniki iz aluminija ali pobakrenega aluminija - 001. del: Tehnična specifikacija

Ta dokument določa lastnosti, preskusne metode ter pogoje za odobritev in sprejetje eno- ali večžilnih električnih kablov za splošne namene z vodniki iz aluminija ali aluminija z bakrenimi oblogami, namenjenih za namestitev v električne sisteme letal. Izolacija teh kablov je zasnovana tako, da prenese napetosti letala pri frekvenci do 2000 Hz. Največja uporabljena napetost pri ocenjevanju teh kablov je 115 V RMS za fazno napetost in 200 V RMS za medfazno napetost pri izmeničnem toku ter 28 V pri enosmernem toku, razen če standardi za posamezne proizvode določajo drugače. Razdeljeni so na tipe, lastnosti katerih so podane v standardih za proizvode. Uporabljajo se preskusi, določeni v tem standardu, razen če je v standardu za proizvod navedeno drugače.
