In this embodiment, the hybrid bracket 3 is made of aluminum alloy and plastic in a sectional combination manner. The aluminum alloy has higher strength and rigidity, while the plastic material has good toughness and corrosion resistance. The aluminum alloy and plastic mixed bracket is applied to the inside of the cable, so that the overall compressive strength of the cable can be effectively enhanced, and the stability and durability of the cable under external force pressure are improved. The compressive strength of the adopted aluminum alloy material is between 410 and 570MPa, and various external force impacts can be effectively resisted. The aluminum alloy and plastic segmentation are combined, so that the compressive resistance of the cable is increased, the flexibility of the cable is ensured by utilizing the characteristics of the plastic, and the construction is convenient.

In this embodiment, the metal used in the metal coating 2 is nickel, and the metal coating 2 is a multi-layer nickel plating layer. Nickel has good corrosion resistance and can effectively resist the corrosion of common corrosive media such as acid, alkali and the like. The method can form a compact oxide film, provides an additional protective layer, prevents substances from directly contacting with a substrate, and prolongs the service life of the component; can effectively block the penetration of moisture. The compact surface structure and the oxide film can prevent moisture from entering the inside of the substrate, and reduce corrosion and damage caused by damp.

In this embodiment, the graphite coating 4 is a multi-layered graphite coating. Graphite coatings generally have good lubricating properties and can reduce friction and wear. The graphite coating forms a uniform and compact lubricating film on the friction surface, and when the two friction surfaces are contacted, the lubricating film can form a sliding plate-like effect, so that the friction force is greatly reduced. This has led to widespread use of graphite coatings in many fields. The dry coefficient of friction of the graphite coating is typically between 0.05 and 0.15 and the coefficient of friction in a wet environment is typically between 0.1 and 0.35. This means that the graphite coated surface has a low friction when in contact with other materials.

In this embodiment, the filler layer 6 is made of an aramid fiber material. Aramid filaments are a high performance fibrous material with excellent strength and tensile properties. The aramid fiber is a high-performance fiber material and has excellent strength and tensile property; elongation at break is typically between 1.8% and 4%; the tensile strength is typically between 2.5 and 4.5GPa (giga pascal).
