Abstract: A method of installing a fiber optic cable (10) upon an overhead power line structure, the overhead power line structure including an overhead power line support (60) and an overhead power line (90) carried by the overhead power line support (60), the method comprising the steps of passing an end of the fiber optic cable (10) through a bore formed in an insulator (120); positioning the insulator (120) at an installation location adjacent to the overhead power line support (60) with the fiber optic cable (10) located within the bore in the insulator (120); bonding the insulator (120) in place once positioned in the said installation location; connecting the insulator (120) to a first end of a conductive carrier (160); and connecting a second end of the conductive carrier (160) to the overhead power line (90) such that the fiber optic cable (10) is supported by the conductive carrier (160) and the insulator (120) as it passes from a first side of the overhead power line support (60) to a second side thereof.
