Unidentified types
Various British pylon types are presently unidentified. Those that can be properly represented with a photograph or a diagram are listed here. Items only accessible via Street View are not included, as no pages link to Street View so long as Google maintain incomprehensible URLs.

The same type is used between Chesterfield and Alfredon in a single earthwire type with a pyramid peak similar to that used on PL1a; this line is also 132 kV.
