Data transmission cable structure

摘要

A data transmission cable (I) comprises at least two conductors, each being isolated by a sheath comprising a non-halogenated material with a low dielectric constant (II), in a filling (III) of flameproof polyolefin with an oxygen limit index of at least 40%, and surrounded by a screen in Al or Al/polyester and an external sheath (IV) comprising a flameproof polyolefin with an oxygen limit index of at least 35%.
