First major 275 kV XLPE cable system in the UK

Commissioned in 2004, a strategic EHV XLPE cable system installed in Glasgow represents three significant advances at the 275 kV level: 1) first 275 kV XLPE long route project in the UK. 2) first significant use of XLPE joints in a UK 275 kV system. 3) use of pre-installed unfilled ducting, which hitherto has been applied only at lower voltage levels. This paper describes the background to and implementation of the project.
