Over the past years, Enemalta Plc has been working on an extensive programme to upgrade the electrical power infrastructure across the Maltese islands. Joseph Cachia & Son Ltd was awarded the tender for Phase 5 which encompasses the supply, installation and commissioning of a 216 count fibre optic link between Marsascala and Marsa. The primary aim behind the fibre optic infrastructure is to provide a high speed and secure communication medium for data. Other in-house systems, such as high voltage power line protection relays, are projected to use the same fibre optic infrastructure. The reliability, resilience and security of the fibre optic infrastructure will therefore be of critical importance where JCS is supporting Enemalta in reaching its targets.
