I have examples of 2 L7 routes, the first with a very typical L7 terminal tower. The other with a different type? Are these both L7? goo.gl/maps/mXTJHVhL9ovgoo.gl/maps/jQR1etcgePF2One difference i noticed was that the 2nd route is twin cables and the first is single. Both are 132kv. Cheers |

Hi. I believe they are both L7 and the first one is simply a modified deviation tower, which seems to be suitable for the purpose, presumably on the basis that there is only one conductor per arm and not two. The modification is no more than a few extensions to give clearance between the conductors on the way down and round the corner at the back. It looks to me like it could be a later (than the original build) replacement. The second one is what I would consider to be a proper termination tower. having said all that, I live near an L7 circuit (dual conductor) with one of each design at either end however and so my replacement theory and single conductor theory may not apply as the ends of the circuit near me were most likely built at the same time.

Hi, it looks like from the info I have that the first link shows an L7 DT but modified with additional cross-arms at 90 degrees whereas the second link shows what is listed as the DJT tower but used in terminal mode i.e without the extra cross-arms at 90. So just goes to show how the towers can be adapted to suit especially the terminal ones.
