AERO-Z®

The cross section is a theorical cross section, the ratio between the cross section and the theorical cross section is between 1.00 and 1.04.

This document deals with:

1. The benefit of technical audits
2. Methodology and Process of a technical audit
3. General criterium for actions required
4. Type of inspected network and its particularities
5. Synthesis of the audits carried out
6. Practical experiences in increasing the line capacity

Given the increasing resistance of both the population and the administrations responsible for town and country planning to the idea of constructing new highvoltage overhead lines, the Belgian utilities have reevaluated the technologies available for meeting the increasing transit needs on the network.

Increasing the transport capacity of existing lines by using a new type of compact phase conductor - called AERO-Z® - has proved to be an especially interesting possibility from both the economic and technical perspectives.

After a brief review of the origin of compact conductors, this report describes the application of this technique to phase conductors and optical ground wire (OPGW) :

1. Compact conductors
• fundamental reason for increased use of compact conductors
• main characteristics and tests
• use of compact conductors in Belgium
2. Optical ground wires
   • problematic of overhead conductors with optical fibres
   • design of the conductors
   • tests performed, measurement methodologies and comparison between the OPGW conductor with round wires and the OPGW conductor with Z-shaped wires
