Abstract
The invention discloses a composite integrated cable. The composite integrated cable comprises a left cable and a right cable. The left cable comprises multiple sets of twisted cable cores and multiple twisted signal lines or power lines. The multiple sets of cable cores and the signal lines or power lines are coated with a first sheath. A separation belt is arranged at the position, between the multiple sets of cable cores and the multiple signal lines or power lines, in the first sheath. The right cable comprises twisted conductors and twisted reinforcing cores. The conductors are coated with insulating layers respectively. The conductors and the reinforcing cores are coated with a second sheath. A connecting rib is integrally connected between the first sheath and the second sheath. A steel belt is arranged in the connecting rib. The composite integrated cable is simple in structure. The cable cores and the signal lines or power lines are separated through the separation belt, mutual interference is avoided, the left cable and the right cable are integrally connected through the connecting rib, and therefore the composite integrated cable can be conveniently wholly buried; meanwhile, the steel belt is arranged in the connecting rib, and therefore whole tensile strength is improved.
