How is an OPGW made?

The design of an optical guard wire is not standardized but there are several possible configurations. Its structural part, in most cases, is made of galvanized steel or ACS (Aluminum clad steel). The optical fibers are positioned inside one or more stainless steel or Al aluminum tubes. Sometimes the use of Inox-Al bimetallic tubes is required.

Depending on the size, the loose tubes contain dozens of optical fibers, typically in multiples of 24 units (24, 48, 96, etc.). The optical cores are filled with a gel to prevent moisture and water from penetrating inside. Depending on the needs, these loose tubes can be positioned in the central position or in the crown. In general, it is avoided to position them on the outer shell so that they can be protected during the installation phases and during the life of the ground line itself. De Angeli Prodotti is able to produce OPGW in all its conformations.

What are the advantages of OPGW?

The major advantage of this particular guard rope lies in the combination of two features:

Protection of overhead power lines from lightning;

Creation of a capillary infrastructural network for data transmission.
