Product description:
The structure of the Tanghu opto-electric hybrid cable is to insert a 250μm fiber into a loose tube made of high-modulus material, and the loose tube is filled with a waterproof compound. The center of the cable core is FRP or metal reinforcement (some structures require a layer of PE underlay on the reinforcement). The wire and the loose tube (and the filling rope) are twisted around the central reinforcing core into a compact and round core, and the gap in the core is filled with a water blocking filler. The double-coated plastic strip (PSP) is longitudinally extruded and extruded into a polyethylene or low-smoke halogen-free (LSZH) jacket.
Features:
· Has good flexibility and mechanical properties.
· Photoelectric integration, fully saving pipeline resources.
· The cable section and the cable section maintain a relatively independent structure for easy introduction, extraction and connection during installation. · Consolidate multiple power lines, telephone lines, TV lines, network lines, monitoring lines, data lines, etc., saving costs.
· Large operating temperature range.
· Large construction temperature range.
· The diameter of the cable and the bending radius are small, and the colleague-compatible optical signal transmission and power transmission can be freely installed in a small space
Technical advantages:
· Optimize transmission line design and save energy.
· Photoelectric integration, transmitting information while transmitting electrical energy, and can detect the working state of the line.
· The optical fiber is compounded in the wire to prevent fiber breakage and fiber breakage caused by lightning on the ground.
· It will not cause electric cable corrosion or cable breakage or fiber breakage caused by field strength.
· There is no hidden danger caused by adding extra line load to the original route.
