Research on a Metal Shielded Braided Reinforced Optical Fiber Composite Rubber-sheathed Flexible Cable for Coal Mining Machines

Abstract

This paper mainly presents the structural design, material selection, manufacturing process key points and performance verification results of a metal shielded braided reinforced optical fiber composite rubber-sheathed flexible cable for coal mining machines. This cable
is designed to address the pain points of underground coal mining machines. By optimizing the conductor twisting structure, adding a metal
shielding braided Layer, Ensemble pressure-resistant and high-temperature resistant optical fiber Unit, and selecting high-performance insulation and sheath materials, it effectively resolves issues such as core breakage, twisting, and sheath bulging and cracking in conventional cables. It is equipped with both Temperature monitoring and fault location functions. It has excellent electrical performance, mechanical strength
and Environment adaptability, and can meet the power connection requirements of coal mining machines and similar equipment with a rated
voltage of 1.9/3.3kV. It complies with the relevant national and industry standards of MT818.
