| Abstract: | The factors responsible for break of aluminium clad steel during optic fiber ground wire(OPGW) produc-tion are classified into 5 categories,i.e,impurities inside the steel wire;scratch on the surface of the steel wire;presence of pile-up on the surface of the steel wire;low sorbite ratio inside the steel wire composition;and uneven pay-off tension during stranding of the aluminium clad steel wires,resulting in too large stess on some wire.The cor-responding counter measures are respectively as follows: control of the quality of the raw material steel wire;control of the quality of heat-treated steel wire;proper transportation,loading/unloading and protection shall be provided during the process of steel wire use;control of the quality of pickled steel wire;and accurate control of the pay-off tension during stranding of the aluminium clad steel wires. |
