Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a corrosion-resistant and wear-resistant cable. Background Art

[0002] Cable is a wire product used to transmit electrical energy information and realize electromagnetic energy conversion. It has a conductor and an insulation layer, and sometimes a strict inner sheath to prevent moisture intrusion, or an outer sheath with high mechanical strength. The structure of the cable is relatively complex, and products with a larger cross-sectional area are usually called cables.

[0003] Patent No. CN205722903U in the prior art discloses a compression-resistant cable. When the cable is subjected to a large external pressure, the insulation layer of the core is squeezed against each other and easily damaged, and adjacent cores are prone to breakdown, causing short circuits and other faults, which not only endangers the safety of the cable itself, but also easily causes great damage to the equipment connected to the cable. Therefore, by connecting the baffle plate and the outer baffle plate with a support plate fixed with an elastic block, the cable has better compression resistance when subjected to external pressure, avoiding excessive compression of the core and causing the insulation layer to be damaged, and effectively protecting the core. However, in actual use, the above-mentioned prior art has relatively weak anti-corrosion and wear-resistant properties, and the cable is often affected by temperature, humidity and various environmental factors during use, which makes the cable susceptible to erosion, thereby reducing its service life and increasing maintenance costs. If the cable is damaged due to corrosion or wear, it is easy to cause power outages and fire and other safety hazards, thereby reducing the stability and safety performance of the cable.
