AI Technical Summary
Existing high voltage cables have difficulty maintaining mechanical stability and shielding performance at high frequencies while remaining flexible, and existing strand-based shielding provides insufficient protection at high frequencies.
The shielding layer is designed with a spiral winding, including 84 to 216 strands, each with a diameter between 0.08mm and 0.22mm, a pitch between 100mm and 250mm, combined with a retaining structure such as polyester rope or tape, plus an aluminum tape shielding screen to ensure effective shielding at frequencies from 1MHz to 100MHz.
This results in better shielding performance at high frequencies, improved mechanical stability and flexibility, reduced material usage, and simplified recycling, all while maintaining the cable's electromagnetic compatibility.
