J L Eve C15 0.1□″ SCA
Contents
Overview
J L Eve C15 0.1″ SCA is one of two sets of towers designed for the joint NEE SL1–MEE SL2 (North-East England and Mid-East England) contract. Alongside the 0.1□″ SCA type, Eve also designed a 0.15□″ SCA type.
The drawings all have corresponding C15 and C23 numbers. Possibly one range was for NEE and the other for MEE; the C23 numbers were added afterwards as all drawing cross-references use only C15.

Lines
Known lines include:
- Malton substation to Scarborough (L4(m) 66 at Malton), North Yorkshire
- Two short lines feeding Malton from Malton substation; at Malton substation they terminate on K9906 DTV towers
-
Sheriff Hutton substation to Malton substation comprises two sections, joined by a PL16 DT through line at an angle of around 54°:
- Eve C15 0.1 from Malton to Barton-le-Willows; the line towers have been strengthened to a design by EDS Consultancy (with several rebuilt completely to a modern recreation)
- PL16 from Barton-le-Willows to Sheriff Hutton; this is likely a truncation and diversion of the original line
-
Malton substation to Whitby; the line towers on this line are “semi-strengthened”:
- Double circuit from Malton substation to Thornton Dale substation
- Single circuit line on double circuit towers from Thornton Dale substation to Dalby Forest (North Riding Forest Park)
- Undergrounded through Dalby Forest in 2013–14 due to extensive tower corrosion
- Single circuit line on double circuit towers from south of Sleights up to Whitby
- A very short 66/11 kV line in Abergavenny, south Wales (SWE region)

Base widths are, uncharacteristically, between the centres of the stubs at ground level.
Some details are approximate or best guesses only due to poor reproduction quality of the original drawings.
