Abstract
The invention discloses a photoelectric composite reinforced flexible cable for 8.7/15kV heavy mobile equipment. Optical cable cores, power line cores and earth wire cores strand to form a cable core, and a semiconductive filler is filled in gap of the cable core. An internal sheath, a braided reinforced layer and an external sheath are sequentially arranged outside the cable core. A nylon reinforced rope is arranged at the center of the cable core and is integrally twisted with the optical cable cores, the power line cores and the earth wire cores into the cable. The braided reinforced layer is formed by braiding polyester fibers in 48-stranded bidirectional-cross braiding structure. Each of the power line cores consists of a power line core conductor, a conductor shield layer, an insulated layer and an insulated shield layer from inside to outside; the conductor shield layer, the insulated layer and the insulated shield layer are of a three-layer extrusion structure. Each of the earth wire cores consists of an earth wire core conductor and an earth wire core semiconductive shield layer. As the cable structure is added with the optical-fiber communication cores, requirements for transmission of equipment running communication signals are met, and functions of the cable are expanded.
