AI Technical Summary
⚠Technical Problem
The existing cable protective layer material, cross-linked polyethylene, has poor flame retardant properties and insufficient bending resistance, resulting in insufficient fatigue resistance and affecting service life.
⚗Method used
The sheath layer composite material is used, and long-chain polymers are modified on the carbon fiber surface to form a micro cross-linked network. Combined with phosphorus-containing flame retardants, the interfacial compatibility and bending resistance of the material are improved.
🎯Benefits of technology
It significantly improves the cable's resistance to bending fatigue and flame retardancy, extending the cable's service life.

Abstract
The application belongs to the technical field of cables, and discloses a copper-clad aluminum composite conductor cable with high bending fatigue life and a preparation method thereof.The cable comprises a cable core, an insulation layer, a shielding layer, an inner lining layer, an armored layer and a sheath layer, wherein the cable core is a copper-clad aluminum conductor, the sheath layer is formed by extruding a sheath layer composite material outside the armored layer, the sheath layer composite material is formed by taking hydrogenated styrene-butadiene block copolymer as a matrix and taking fiber-based modified reinforcing material and the like as an additive through a melting extrusion process, the addition of the fiber-based modified reinforcing material can not only effectively enhance the mechanical strength of the sheath layer material, but also effectively improve the bending resistance and flame retardance of the sheath layer composite material by using special flexible segments in long-chain polymers and phosphorus-containing flame retardants, so that the cable can have a longer service life.
