High-temperature shielded cables are a type of power transmission cable specifically designed for high-temperature environments. Their core function is to maintain stable signal or power transmission performance in complex scenarios such as high temperatures and strong electromagnetic interference through special materials and structural design.
The core technology of high-temperature shielded cables lies in the coordinated design of the conductor, insulation layer, and shielding layer. The conductor typically uses high-temperature resistant materials such as tin-plated copper or nickel-chromium alloys to ensure low resistance characteristics even at high temperatures. The insulation layer uses high-temperature resistant polymers such as silicone rubber and fluoroplastics, with a temperature resistance rating of over 200℃, while also possessing excellent electrical insulation properties.
The shielding layer, through a metal braided or aluminum foil-wrapped structure, effectively blocks external electromagnetic interference, preventing signal distortion or power loss. Furthermore, the outer sheath often uses flame-retardant and oil-resistant materials, further enhancing the cable's adaptability to harsh environments.
