According to the online edition PROkabel, Prysmian Group Company which occupies a leading position in the cable market and cabling systems for telecommunications and energy purposes market, has signed a contract for record amount of about 800 million for the development and production of cables for the large-scale Western HVDC Link project.
This project calls for construction of a new high voltage direct current underwater system between England and Scotland. Nowadays this is the largest and the most expensive order in the cable business.
Siemens has also signed a contract valued at sum of 1 billion pounds that implies construction of the first power transmission underwater system between England and Scotland, the power of the new system — 2.2 thousand MW. The network will run from Hunterston located in the county of Ayrshire, Scotland, to the Wirral Peninsula in Cheshire, England.
The whole process of the global project will be a consortium of Prysmian and Siemens responsible for HVDC converter stations. The total amount of the construction performance contract signed by a consortium of Prysmian and Siemens joint venture with Scottish Power Transmission and National Grid Electricity Transmission — NGET / SPT Upgrades Ltd comprises € 1.1 billion.
This new submarine cable will be put into service by the end of 2015, will operate at full capacity in 2016. The construction of a new submarine cable is of strategic importance for modernization of the British power grid as far as it will allow the UK to implement a program aimed at reducing the amount of hydrocarbons and industry development of alternative, renewable energy.
This project has been a record not only regarding the cost of the order and the contract signed but also through the use of new technologies of cable industry. At the record voltage level the system will operate with minimal losses but this power has never been used for long-haul main lines.
The purpose of the construction of a new cable line is the connection of renewable energy sources located in Scotland with the electric energy consumption centers in England; bidirectional transmission capacity is also possible. The advantage of the construction of an underwater cable lies in the short terms of the project implementation.
Innovative technology developed by Prysmian involves the use of cables with multi-ply paper-propylene insulation with enhanced thermal and electrical characteristics. Company has got such a profitable order due to its irresistible competence in the production of high quality cables as well as great experience in this area.
Length of the new cable system which connects England and Scotland is 400 miles, underwater part will go through the Irish Sea.
