FRP glass fiber (non-metallic) strengthening core
FRP glass fiber (non-metallic) strengthening core has the advantages of all electrolytes, a wide range of use, corrosion resistance, good compatibility with other optical cable materials, long service life, will not cause harmful gas caused by metal corrosion hydrogen damage affect optical cable transmission performance. Non-metallic materials are not sensitive to electric shock, not subject to electromagnetic interference, with better tensile strength, high elasticity, high bending modulus and low elongation, small specific gravity (about 1/5 of steel wire), the same size can provide large length of disk length, greatly improve production efficiency and yield.
