Light construction towers

The “light construction” types are four 132 kV tower series designed for the North of Scotland Hydro-Electric Board that use Tiger (0.125^□″ SCA) conductor, rather than the conventional Lynx (0.175^□″ SCA). Previously known as “J L Eve 0.125”, two of the types are in fact Blaw Knox.

These towers appear to have a much lower lifetime than the stronger Lynx towers and are already being replaced and demolished one line at a time.

The four types are as follows:

• J L Eve C772: possibly the oldest type, designed between 1957 and 1960 and used on the line between Inveraray and Carradale. No earthwire.
• Blaw Knox T1498, designed in 1959 and used on the line between Inveraray and Taynuilt. No earthwire.
• J L Eve C1415, designed ca. 1970 and used on the line between Dunoon and Garelochhead; as C772 (Inveraray–Carradale) but with an earthwire.
• Blaw Knox T2639, designed in 1975 and used on the line between Quoich and Broadford; as T1498 (Inveraray–Taynuilt) but with an earthwire.
