Cable shielding is a layer of metal sheath added to the exterior of the cable to protect the cable from external damage, while improving the mechanical strength of the cable and improving its tensile strength and resistance. 'extrusion. Metal materials for cable shielding can be steel strips, steel wires, aluminum foil, etc. Cable shielding of different materials and structures can be selected and designed according to different usage environments and requirements.
Cable shielding is mainly used in power engineering, petrochemical industry, aerospace, communications and other fields that need to operate in harsh environments . In the petrochemical industry, due to the harsh working environment, often severe conditions such as strong acid, strong alkali, high temperature and pressure, cable shieldingbles is a necessary protective measure. In the fields of communications and aviation, cable shielding can also play an anti-interference role to ensure the quality of signal transmission.
With the continuous development of science and technology, cable armor is also constantly upgraded and improved. At present, more and more cables use new lightweight, high strength and corrosion resistant materials to make the armor layer, such as carbon fiber, glass fiber and other materials used for submarine cables. At the same time, there is also the emergence of new armor technologies, such as special rubber coatings, aluminum alloy sleeves, etc., which can further improve the mechanical strength and damage resistance of cables. In short, cable armor will continue to play an increasingly important roleincreasingly important in continuous technological improvement and application expansion.
