Consulting Services, OPGW Retrofit on High Voltage Transmission Lines Project

Project:

The main objective is to build-on EDM’s integrated telecommunications and SCADA network with sufficient coverage, capacity or resilience to meet some of the most fundamental requirements of its core electricity supply operations and its enterprise management applications.

Existing Overhead transmission lines shall gradually be fitted with an OPGW. The Retrofit of the transmission lines mentioned below are part of the telecommunication backbone but for which no further investment has been foreseen in the near future

• Replacement under live condition of the existing steel earthwire of the Matambo - Chibata 220 kV transmission line (320 km) with OPGW of an adequate size similar to the existing earthwire and fitted with an appropriate number of optical fibres.
• Replacement under de-energized conditions of the existing steel earthwire of the Matambo - Chimuara 220 kV transmission line (294 km). with OPGW of an adequate size similar to the existing earthwire and fitted with an appropriate number of optical fibres.

Associated works (repeater stations, splicing, fibre connection (FOC) to respective substations, etc.) necessary to be completed in this scope for the two transmission lines.
