description The invention relates to a vide coaxial cable in a travelling comprehensive cable and used for elevators, comprising an internal conductor (1), an insulated layer (2), an external conductor (3) and an external protection layer (4); the internal conductor (1) comprises a plurality of copper-clad steel conductors which are arranged in regularly-twisted shape (11) with small pitch; the video coaxial cable of the invention has the beneficial effects that according to the flexible testing method specified in the standard of GB5023.2, after 30 thousand times of bending tests, the transmission performance of the cable can still meet the requirement of the GB/T14864-93 and the mechanical flexible performance is better than the requirement on the product in the standard GB5023.6.
