Abstract
The invention provides a multipurpose optical fiber composite overhead ground wire. The overhead ground wire can sense external environment changes self, and furthermore adjusts a working state, and the service life is prolonged. The multipurpose optical fiber composite overhead ground wire comprises a central optical unit. The central optical unit is located in a central cavity formed by outer layer metal wires through coating. The outer layer of the central optical unit is intertwisted with at least a layer of the outer layer metal wires. The central optical unit comprises a stainless steel pipe, an optical fiber and a fiber paste. The optical fiber comprises at least an induction optical fiber and at least common communication fiber. The induction optical fiber and the common communication fiber are e arranged in the inner cavity of the stainless steel pipe. The fiber paste is loaded in gaps of the inner cavity of the stainless steel pipe. The fiber paste has optical fiber protection and water resistant functions.
