Algeria: Pirelli to supply 4000 km of fiber optic cable for installation on energized 220 kV power lines
"Pirelli has been awarded two major contracts for the provision of overhead optical cable systems in Algeria. The two contracts, worth a total of USD $20m (including installation activities), have been signed with the system integrator Telecommunications Consultants of India (TCIL), and will provide the final customer, the Algerian power and gas company SONELGAZ, a major optical communications backbone."
"Both contracts involve the installation of the optical cables under live line conditions using Pirelli patented installation methods ..."
"The first contract covers 3000 km of OPGW (Optical Ground Wire) to be installed on energized 220 kV overhead transmission lines on a turnkey basis. Installing OPGW on energized transmission lines requires use of the unique Pirelli-developed installation methodology, which simultaneously ensures safety and cost-efficiency. The OPGW cable performs a dual role. It protects the electrical network from fault current and lightning damage in the same manner as a conventional earth wire, whilst the inclusion of optical fibres -- completely unaffected by the electrical environment -- within the cable, provides a telecommunication system capable of transmitting high speed voice, data and video traffic."
"The second contract covers 1000 km of lashed cable to be installed on energized 220 kV overhead transmission lines using a Pirelli robotized system. The lashed cable is a dielectric optical cable that, attached to the existing earthwire of the transmission lines, allows the installation of optical fibres in electrical networks at high speed and reduced cost. The Pirelli installation system, utilizing radio controlled robots, allows live line installation without risk to personnel working in the vicinity of the line."
