What designs / structures / shapes are there?
[N.B. Many of the designs mentioned are shown at the end of the descriptions.] In the UK we have three common designs, called the L2, L6 and L12. The L2 is designed for 275kV lines, the L6 for 400kV, and the L12 for either 275kV or 400kV lines. The L6 is slightly taller and broader, with a slightly stockier look. There are examples of these in this pdf on the National Grid website. However, there are many more models. If you would like to learn more, see this illustrated guide to different pylon/tower model types. Geeks only! In general, there are “suspension” pylons where the insulators hang down and these are the most common. There are also deviation pylons, where the lines turn a corner (sometimes only slight), and these are called “angle pylons” on my site. These are “tension” pylons where the insulators go horizontally out from the arms of the pylon. Sometimes a pylon that is over-spec’d is used for a lower voltage circuit. The size of the string of insulators provides a clue as t
