AI Technical Summary
The existing composite cables have a simple tensile structure design, which makes the cables prone to fatigue fracture when stretched and bent, and the shielding layer is prone to loosening under stress, resulting in a decrease in shielding effectiveness.
The cable adopts a structural design consisting of an inner core layer, an inner tensile layer, a composite shielding layer, and an outer sheath layer arranged from the inside out. This includes tensile filler, a mesh cylinder structure of galvanized steel wire and aramid fiber, an elastic buffer structure of reinforcing metal plates and fins, a hexagonal honeycomb hollow cylinder structure of copper wire and PBO fiber, and an FRP reinforcing core inside the outer plastic sheath, forming a multi-layer tensile and energy absorption system.
It improves the tensile strength and structural stability of composite cables, extends the dynamic fatigue life of cables, enhances electromagnetic shielding effect, and prevents excessive elongation of cables due to their own weight when laid vertically or overhead over long spans.
