Cables capable of carrying both electrical power and optical transmissions will extract more service from new or existing low and medium tension network structures.
OPGW cables are designed to work with the overhead lines on which they are installed. For example, the short circuit current is verified; essential for the calculation of the temperature rise in each circumstance and the required cooling time.
The OPGW conductor is usually composed of a central non-metallic tubular structure containing optical fibres, situated inside the steel or electro-welded tube. The tube is surrounded by one or more layers of steel or aluminium, aluminium alloy and steel alloy wires. The specific type, size and number of these wires are selected to suit each individual application
