AI Technical Summary

⚠Technical Problem

Existing cable sheaths are prone to aging under harsh conditions such as high outdoor temperatures, especially under ultraviolet radiation and drastic temperature changes, leading to cracking, embrittlement, and decreased insulation performance. Traditional polytetrafluoroethylene (PTFE) films have limited improvement effects.

⚗Method used

The sheath structure is formed by three-layer co-extrusion, including a PTFE outer sheath, a THV middle sheath, and a PCTFE inner sheath. By optimizing the layer thickness ratio and bonding tightness, the structural stability is enhanced and it can adapt to a wide range of temperature environments.

🎯Benefits of technology

It improves the cable sheath's resistance to ultraviolet radiation and temperature adaptability, maintains structural stability, and enhances the cable's overall anti-aging ability.

Abstract

The application discloses an anti-aging cable and belongs to the cable field. The anti-aging cable comprises a cable core and a shielding layer, a filling layer and a heat insulation layer. The shielding layer is wrapped outside the cable core. The filling layer is filled between the cable core and the shielding layer. The heat insulation layer is wrapped outside the shielding layer. The sheath comprises a PTFE outer sheath layer, a THV middle sheath layer and a PCTFE inner sheath layer. The PCTFE inner sheath layer is wrapped outside the braided layer. The THV middle sheath layer is wrapped outside the PCTFE inner sheath layer. The PTFE outer sheath layer is wrapped outside the THV middle sheath layer. The application has the effect of improving the anti-aging capability of the cable.
