Composite cable

The invention relates to the technical field of communication cables, in particular to a composite cable which comprises an optical fiber conductor, an inner shielding layer and an inner heat insulation layer which sequentially surround the outer portion of the optical fiber conductor, a middle shielding layer and a middle heat insulation layer which sequentially surround the outer portion of the inner heat insulation layer, and an armor layer and a sheath layer which sequentially surround the periphery of the middle heat insulation layer. An inner filling layer is filled between the inner heat insulation layer and the middle shielding layer; the electrical conductors are distributed between the middle heat insulation layer and the armor layer in a surrounding mode, conductor heat insulation layers are arranged outside the electrical conductors in a surrounding mode, an outer filling layer is filled between the armor layer and the middle heat insulation layer, and a double-layer inner heat insulation layer an
