ICING MEASUREMENTS AT DEADWATER FELL TEST SITE
A severe weather test site was set up on Deadwater Fell on the UK English/Scottish border. It is at a land height of 580m and has a single 190m test span. This paper describes the site including the meteorological instruments and video and logging instruments. Conductors erected at the site are fitted with load cells and vibration monitors. Conductors currently under test are J-Powers Gap, CTCs Lisbon and Oslo ACCC and Lumpi-Berndorfs (Z) TAL/HACIN types. These new conductor types are being compared with standard AAAC Sycamore and ACSR Lynx for wind/ice accretion tests and vibration performance. The Gap and Lisbon conductors have undergone wind/ice load tests over three winters and so have, in total, suffered over 60 wind/ice incidents with the worst incident causing tension increases of up to 100% in the conductors. An Oslo (ACCC) conductor was erected in 2008. Over the 2008 to 2010 these conductors were tested for vibration over a range of tensions and compared with Sycamore and Lynx as control conductors. Conductors tested at equal % Ultimate Tensile Strength (UTS) and also at equal sag. Tests had also been carried out in 2007 on smooth and round stranded conductors of conventional aluminium alloy for Nexans Benelux. Data will be shown for the new conductor types in comparison to standard conductors. The aim of these tests is to determine which new conductor types are suitable to provide increased power capacity at 33 to 400kV lines in ice-prone areas in the UK.
