Abstract
The invention discloses a communication cable capable of preventing saline-alkaline corrosion and rat/ant gnawing. The communication cable comprises a salt-tolerant outer sheath layer, a metal braided shield layer, a low-smoke zero-halogen polyolefin packing layer, an inflaming-retarding protection layer and a copper cable core in sequence from the outside in. Two anti-insect/ant-tearing ropes are radially arranged between the salt-tolerant outer sheath layer and the metal braided shield layer. The inflaming-retarding protection layer is formed by decabromodiphenyl ethane, antimonony oxide, paraffins, calcined clay, silicon rubber, fluorinated silicone rubber, lubricating oil and epoxy triglyceride. The low-smoke zero-halogen polyolefin packing layer is formed by polyethylene, micron calcium carbonate nucleation master batch and a metal binder. Each anti-insect/ant-tearing rope is formed by stranding four strands of glass fibres soaked with an anti-insect/ant extraction solution and four strands of tinned copper wires. The communication cable is high in tensile strength, easy to bend, good in flame resistance, capable of preventing gnawing of rodents, resistant to seawater and salt spray corrosion, resistant to seawater and humidity dipping, resistant to wind erosion and good in anti-torsion performance.
