The T shape with the hanging 'diamonds' carrying the cables will have incredible turning moments at every node junction never mind the stresses and overturning moments at the bolted base on what will need to be a massive foundation in weak or unstable ground across bogs/ moorland/ friable rock/ as Dell, Zolders and TVC have already said causing the rigid joints to become prematurely fatigued under wind/ ice load. Stainless steel would cost a fortune. Replacement and maintenance alone would be a nightmare.

One piece manufacture and delivery for a 20m high T shaped structure exceeds the max length permitted on UK roads without police escort for each one on a heavy low-loader requiring rolling road blocks.... and how do you lift one into place and get them into remote locations ... doubt even a Chinnook helicopter's big enough to lift one of them. [I wouldn't mind if it was elegant!]


+1 I bet it costs more to build and maintain than the 1920's original, it isn't as mechanically efficent, plus you will have to dig a 50 foot hole and fill it with 20 tons of concreate to keep the frigging thing from falling over. Another example of someone trying to solve a problem than doesn't actually exist.

Shame there wasn't a design with a small wind turbine on it. If there aren't technological hurdles, I'd have thought a small windmill on every pylon in the country would generate quite a bit of energy without causing additional "eyesores".

There is a design with a big turbine in it...

all the other entrants failures are here (in which other designs also incorporate wind turbines)

Access, serviceability? Also, not sure they will have stress tested the design, the cross beam with such a narrow depth isn't going to take the weight of those fully iced cables. Sorry to be a practical engineer about this, but those fancy-pants designers can draw what they like, it doesn't mean it will work.

Yes, how do engineers access the cables - need a cherry picker presumably, not practical in most fields....

If there's any problem with them being eyesores (and personally, I don't mind them at all), then all they need do is paint the top halves white. The pylons in France are often painted, red and white broad horizontal bands, and the white bits disappear against most skies.

Also, I bet the people who complain about them couldn't do without their electricity....

I think there's enough variety in the style we have, as it is, it's interesting to see how the shapes vary along a line, presumably for different stress loads and so on.

Most are surveyed from helicopters using infra red or similar to see hotspots where failures are likely... then they can be lowered from the helicopter using a special cradle onto the LIVE cable!!!! to repair it... saves switching off the supply... it's scary stuff- seen it done but not for me.

You Tube video of a similar thing....
