OPGW Cable SystemThe PRYSMIAN solution for the integration of telecommunications networks on high voltage overhead lines

Overhead optical fibre cable systemsOverhead optical fibre cable systems have become a key factor in telecommunications networks used by operators and power utilities. Due to the fact that no civil works are required and the rights of way have already been established, it is possible to minimise costs and, most importantly, the time required to begin network operation.

Prysmian offers its customers a complete range of overhead optical systems:OPGW Cable SystemsComposite optical ground wire system for installation on high voltage electric lines.

Self-supporting cable system (ADSS)Self-supporting optical cable system for all types of lines: electric lines, overhead distribution lines for railways, etc.

Lashed cable systemOptical cable system lashed to the ground wire or the phase cable on the electric lines.

OPPC cable systemComposite optical phase cable system, for high voltage electric lines up to 135 kV.

2OPGW-PRYSMIAN

OPGW-PRYSMIAN Cable System, the never wrong decisionCustomers who choose the Prysmian OPGW system can be sure that their decision will lead to a successful experience during installation and operation. The main advantages of Prysmian OPGW are the following:

Introducction

> High reliability and demonstrated experience High reliability supported by over 110,000 km. of cables installed, with systems in operation since 1983 in more than 70 countries in the five continents.

> Supply of a full system Easy to install since Prysmian OPGW includes all components which the system requires from end to end:

OPGW cables and terminal cables Joint boxes, optical distribution frame and connection accessories Components for securing the cable to the high voltage towers Engineering and installation services, with turn key projects Drum lengths up to 10.000 m.> Manufacturing capabilitiesThe OPGW-PRYSMIAN cable is produced at Prysmians OPGW Centre of Excellence in Vilanova i la Geltr (Spain) and also in Sorocaba (Brazil) and Wuxi (China) facilities. With these three factories Prysmian can deliver cable to any part of the world, with very high flexibility and in quantities synchronized to the timing of the project.

> Aluminium Tube TechnologyThe extruded aluminium tube technology used by Prysmian in the manufacture of OPGW Composite Optical Ground Cables has demonstrated its high quality and reliability, with fully satisfactory installations in operation for more than 20 years. Furthermore, the ongoing research in new materials and the experience gained ensure the continuous development of our products.

Terminal CablesThese cables are used to connect the optical fibres of the OPGW cable at the end of the high voltage line to the optical distribution frame in the substation.

The most widely used cable types are as follows:The EKE cables, whose fully dielectric design prevents the generation of secondary currents. If there are rodents in the area, these cables should be installed in duct.

Terminal Cable: EKEThe EKH9E cables equipped with anti-rodent metal armour. This armour must be connected to earth to prevent electric discharge when secondary currents are generated.

Terminal Cable: EKH9EThe EKDE cables whose fully dielectrc anti-rodent protecction, combines the advantages of the two prior solutions.

Terminal Cable: EKDEIn all of these cables, Prysmian can offer a wide range of sheaths which respond to specific installation needs . We supply the fire resistant Afumex type, hydrocarbons resistant, termites resistant, etc.

Optical FibresThe optical fibre of the cables supplied by Prysmian is manufactured in-house and is designed to provide optimum transmission services. These fibres are used primarily in telecomunications networks characterised by long distance links and high capacity.

Prysmian can supply its Magnilight ITU-T G.652 D for metro applications upon request.

Non zero dispersion shifted FreeLightFibre designed for DWDM applications. It is characterised by very low dispersion from 1530 to 1625 nm and a high effective area, which prevents the non-linear effects of high speed in this type of transmission, offering improved service in comparison to the previous fibres.
