AI Technical Summary

Technical Problem

Traditional armored cables suffer from poor buffering performance, susceptibility to aging and cracking, insufficient bonding strength, and unreasonable structural design. These issues make the cables prone to insulation cracking and conductor strand breakage under mechanical impact, vibration, and compression, affecting the safety and stability of power transmission.

Method used

A composite layered buffer structure is adopted, including an inner layer of flexible elastic material, a middle porous material, and an outer layer of high-strength elastic composite material. Combined with an adhesive layer and an anti-corrosion coating, the armoring process parameters are optimized to achieve efficient absorption and dispersion of impacts and vibrations of different intensities.

Benefits of technology

It significantly improves the cable's impact resistance and bending fatigue life, reduces the impact on the internal insulation layer and conductor, ensures the long-term stability of the buffer performance and the stability of the overall structure, avoids delamination and detachment, and improves the cable's operational reliability and safety.

Abstract

This invention discloses an armored cable with a buffer structure and its manufacturing process. The armored cable includes a cable core, an insulation layer, a buffer layer, an armor layer, and an outer sheath. The buffer layer has a composite layered structure, including an inner buffer layer, a middle buffer layer, and an outer buffer layer. The inner buffer layer is tightly attached to the outside of the insulation layer, and the outer buffer layer is tightly attached to the inside of the armor layer. The middle buffer layer is located between the inner and outer buffer layers. The inner buffer layer is made of a flexible elastic material, the middle buffer layer is a porous buffer material with several buffer units evenly distributed inside, and the outer buffer layer is made of a high-strength elastic composite material. This invention avoids problems such as insulation layer cracking and conductor strand breakage, thus improving the operational reliability of the cable.
