Pylon schemes
Contents
Overview
This page is not a catalogue of all lines and schemes, just those schemes that have a name. Not sure what this page is for but it had to be split out from the series page as part of disentangling the confusion between scheme designations and tower suite designations. The entries are only in the vaguest hint of a meaningful order, as virtually nothing is known about any of these schemes.
See the regions page for a guide to the regions and their abbreviations and prefixes.
Primary Lines
Original CEB PL schemes, plus later schemes of 132 kV and above.

| T(2) CEGB – L280 | PL7? | 132 kV line mods – Northfleet |
† The CEA only existed between 1955 and 1957, and since L236 is already dated to after 1957, L256 is presumably going to be around the same time.
Secondary Lines
33 kV and 66 kV on lattice towers, mistakenly referred to as “pre-Grid” towers. Tower diagrams pending some way to name the different tower types on this site.
