60° and 55° angle tower series comparison
Contents
Overview
Use this page to help identify UK electricity pylon series by D60, S60 and D55 angle towers. Within each voltage class the tower series are arranged in approximate chronological order of introduction. See the comparisons page for other comparisons. See the series page for the list of known series.
Not all series are covered by this page; coverage is limited to available data. See the project completeness page for details.
Three and four circuit and dual voltage
The K1373 D type is three circuit (2 × 66 kV plus 1 × 33 kV).
Double circuit
60° double-circuit angle towers by series.
33 and 66 kV
132 kV
Note that some K1373/K4611-type lines—whose towers are depicted above—have been uprated for 132 kV.
The designated angles for the Tummel–Keith types are not known.
275 kV
Note that L2 towers were designed for 275 and 380 (or 400) kV and are listed under 400 kV below.
400 kV
Single circuit
60° single-circuit angle towers by series.
33 and 66 kV
110 kV
132 kV
The following types have been observed but no documentation has been recovered and the designations are for convenience only:
