Hebden Bridge to Elland
Contents
Overview
A 33 kV single-circuit lower-voltage line existed between Hebden Bridge and Elland, West Yorkshire, constructed for the Yorkshire Power Company. Latterly it ran from Hubberton Green (outside Sowerby) to Salterhebble, Halifax (north of Elland). The line towers used an unusual configuration where the top crossarm was wider than the bottom one, just as was done with Woodhouse masts. Research by Tom Gloag suggests that this line pre-dates the national grid, being conceivably constructed prior to 1926.
The line was demolished sometime after 2016. No details currently exist for the line; the voltage of 33 kV is derived from the three-unit insulators (standard for 33 kV) and the crossarm spacing being sufficient only for this voltage (no space for longer insulator strings).
In 1997, the termination at Salterhebble was relocated slightly onto a custom-designed terminal tower. This tower was designed by Balfour Kilpatrick. This tower, at 18.8 m in height, is unusually tall for the voltage, which may relate to the geography; typically, termination at lower voltages is done on wood poles.

Tower forms
It’s not known whether any material for these towers will ever be recovered. Presently on the drawings for the custom terminal tower have been found.
