The utility model discloses a photoelectric composite cable which comprises an inner core and is characterized in that the inner core is composed of two optical units, two electric units and four ground wires, the two optical units and the two electric units are distributed in a cross shape in the inner core, and the four ground wires abut against the positions between the optical units and the electric units in an X shape; a reinforcing piece, a wrapping tape, a shielding layer and a sheath are sequentially distributed outside the inner core from inside to outside; according to the utility model, the stainless steel soft steel in the optical unit is used for the first protection, the aramid fiber layer is used for the second protection, and the reinforcing member is used for the third protection, so that the compression resistance and the clamping resistance of the optical fiber are fully enhanced through the three protection layers; and meanwhile, the aramid fiber layer and the reinforcer are woven by adopting a plurality of strands of aramid fibers, so that the protection effect of a traditional metal armor can be achieved, and the weight of the cable is reduced on the basis of ensuring the tensile and compressive properties of the cable.

The utility model relates to the technical field of pipelines, in particular to a wear-resistant and corrosion-resistant rubber pipe which comprises a double-corrosion-resistant rubber layer, a middle reinforcing layer is arranged between the double-corrosion-resistant rubber layer, a wear-resistant spiral ring is arranged outside the double-corrosion-resistant rubber layer, and the wear-resistant spiral ring and the double-corrosion-resistant rubber layer are connected through a butt joint plug bush. The butt joint plug bush comprises an inner ferrule connected with the double-corrosion-resistant rubber layer and an outer ferrule connected with the wear-resistant spiral ring, the butt joint face of the inner ferrule and the outer ferrule is an inclined face, a slot is formed in the outer wall of the inner ferrule, and insertion teeth matched with the slot are arranged on the inner wall of the outer ferrule. A butt joint plug bush is arranged at each of the two ends of the wear-resistant spiral ring; according to the utility model, the wear-resistant sleeve with the strongest wear-resistant property can be arranged at the most worn position in use in a targeted manner, so that the overall wear-resistant property of the pipe is effectively improved; by adopting the design of double rubber layers, the corrosion resistance is improved; the middle reinforcing layer is arranged, so that the overall tensile property and the flexibility of the rubber pipe are improved.

This utility model discloses a three-layer insulated wire with a coating, including a wire core. The outer wall of the wire core is wrapped with an enameled layer, and a first insulating layer is wrapped around the enameled layer. A pressure-resistant metal ring is sleeved on the outside of the first insulating layer. A second insulating layer is wrapped around the outside of the pressure-resistant metal ring, and a third insulating layer is wrapped around the outside of the second insulating layer. Beneficial effects: This utility model features a pressure-resistant metal ring, which is a short circular ring positioned between the first and second insulating layers. After the first insulating layer is applied, workers can individually sleeve the pressure-resistant metal rings onto the outside of the first insulating layer. The positioning grooves and positioning strips prevent arbitrary rotation. The metal pressure-resistant rings significantly improve the overall compressive strength, provide good rodent-proof protection, and reduce the probability of deformation and breakage. Furthermore, there is no rigid connection between the pressure-resistant metal rings, so it does not affect large-angle bending, wiring, or use.
