OPGW (Optical Ground Wire)

This is a smart use of the widespread grid of ground wires for the transmission of data.

Introduction

This is a smart use of the widespread grid of ground wires for the transmission of data.

For this purpose, for more than 20 years, the TSO (Transmission System Operators) are gradually replacing all the galvanized steel and ACS (Aluminium Clad Steel) ground wires with OPGW (Optical Ground Wire) that, through the insertion of numerous optical fibres, allows a capillary and fast data transmission.

Engineering

The design of these ground wires is various and not standardized and it contains an optical core in the center, or in the layers, or multiple, etc.
The optical cores can be composed of Inox St or Al or Inox-Al tubes and contain dozens of optical fibres, typically in multiples of 24 units (24, 48, 96, etc.).
De Angeli Prodotti is able to produce OPGW in all its conformations.

Advantages

The advantage of this particular ground wire is in the combination of two features: protection of the overhead power line  from the lightning and the establishment of an extensive infrastructure network for the data transmission.
