Application Summary AI generated

GB/T 7424.4-2003 specifies the requirements for optical fibre composite overhead ground wires (OPGW), which integrate optical fibers into the ground wire of overhead power transmission lines. It is applied in the electric power industry for telecommunications and monitoring functions, where the cable serves both as a lightning protection conductor and a medium for data transmission. The standard covers construction, mechanical, and optical performance criteria for use in high-voltage transmission line installations.
