MESSENGER WIRE FOR POWER DISTRIBUTION LINES AND PROCESS FOR FORMING A MESSENGER WIRE FOR POWER DISTRIBUTION LINES

摘要

The messenger wire comprises a tubular metal element (10), which is surrounded by metal strands (20) arranged in a spiral configuration and internally houses at least one optical fibre (30). The messenger wire further comprises at least one tubular electrical insulating element (40), which surrounds at least one optical fibre (30) and is internal to the tubular metal element (10). The process of forming the messenger wire involves gradually and continuously forming, around the optical fibre (30), the tubular electrical insulating element (40), around which the tubular metal element (10) is formed, which is to be surrounded by the metal strands (20).
