Aerospace series - Cables, electric, general purpose, with conductors in aluminium or copper-clad aluminium - Part 001: Technical Specification
This European Standard specifies the characteristics, test methods, qualification and acceptance
conditions of single and multicore electric cables for general purpose with conductors in aluminium or
copper-clad aluminium, intended for installation in aircraft electrical systems.
The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding
2 000 Hz. Unless specified by individual product standards the maximum demonstrated voltage of rating
of these cables is ac 115 V rms phase to neutral and 200 V rms phase to phase and 28 V d.c.
They are divided into types, the characteristics of which are given in the product standards. Unless
otherwise specified in the product standard, the tests defined in this standard apply.

Aeronavtika - Kabli, električni, za splošne namene, z vodniki iz aluminija ali pobakrenega aluminija - 001. del: Tehnična specifikacija
Ta evropski standard 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 AC 115 V RMS za fazno napetost in 200 V RMS za medfazno napetost ter DC 28 V, razen če standardi za posamezne proizvode določajo drugače.
Razdeljeni so v vrste, lastnosti katerih so podane v standardih za proizvode. Uporabljajo se preskusi, določeni v tem standardu, razen če je v standardu za proizvod navedeno drugače.
