Design of A Novel Fiber Optics-Composite High-Voltage Cable With Its Performance Simulation

This study introduces a novel fiber-optic composite high-voltage cable for real-time tracking of conductor temperature, strain, and vibration. The cable integrates single-mode and multimode optical fibers in a double-helix armored structure, which enables direct thermal and mechanical sensing. Mechanical validation under standardized protocols confirmed its strong tensile properties, meeting the requirements of high-voltage installations. Optical characterization showed low attenuation values for single-mode and multimode fibers, meeting industry thresholds. Bending simulations verified minimal signal attenuation under operating conditions.
