Mine-electric hybrid cable
Product Description:
1. Optical unit
2. Feeder
3. Center reinforcement
4. Water-blocking material
5. Armor layer: steel-plastic composite belt
6. Outer sheath: blue polyvinyl chloride
The structure of the mine-photovoltaic hybrid cable is that a 250μm optical fiber is sleeved into a loose tube made of high-modulus material, which is filled with a waterproof compound. The center of the cable core is a metal reinforcement (metal reinforcement plus a layer of PE cushion). Wires and loose tubes (and filler ropes) are twisted around a central reinforcing core to form a compact and rounded core, and the gaps within the core are filled with water-blocking material. The double-sided plastic-coated steel tape is longitudinally wrapped and then extruded into a polyvinyl chloride (PVC) sheath into a cable.
