Shortlisted Entry 2

P33 Bystrup - The T-Pylon

Team: Bystrup – Architecture, Design & Engineering

The T-pylon is designed as a slender and compact tower. The reduced visual impact makes it fit well into different settings as a no-nonsense icon. The conductors are arranged in a triangular configuration that minimizes the extent of the circuits and the magnetic fields. To adapt to the changing character and colors of the landscape as well as the aggressiveness of the local atmosphere the pylon is available as painted, hot dip galvanized, in Corten or stainless steel.

where is the earthwire, are all towers tensions towers, what is the span length compared to existing towers. Are the specified conductor separations maintained, what are the insulators made of. More questions than answers in this design.

A no-frills design that works quite well. Difficult to have strong feelings about loving or hating it. Maybe this is the best way to please the most people though.

Neat trick choosing the sky colour (white clouds) to make the hangers and cables seem to disappear, this doesn't work with other sky conditions and when the kit has rusted. Much better to bury the cables or not have them (local small scale generation)
as a design it is boring.

agree with JF above, no earth wire on this system though it would be easy to string down the middle... difficult for it to protect the external circuits though... also, how is it intended for these pylons to be accessed for maintenence work? cant really
see an easy way to get around them as such...

This is the only convincing entry, simple enough not to be compromised when eventually realized and pretty elegant all in all. This wouldn´t be an eyesore when replicated in the landscape and very timeless in design. A bit boring maybe, but nice. It´s
a Volvo.

Contrary to the comments so far, this design has two earth wires which provide effective shielding for the conductors below. The three conductors are hung of the insulator sets, one at the bottom of the arrangement with the other two being located at either
end of the horizontal members. Standard composite insulators are planned. Maintenance is the key issue with this pylon, you'd need a mobile platform to do maintenance work. Also, there is a single point of failure where the insulators are hung - if the shackle
fails you lose all three conductors. Finally, I wonder about the mechanical design. With the large conductors from an L12 tower being used, the horizontal members at the top of the tower will need to support some large loads. So, it's compact owing to the
conductor arrangements, pleasing to look at but maintainability is not great.

I like the compact design and reduced magnetic fields

This is my favourite (No 7 being my 2nd favourite) - it's the least intrusive and most elegant

It looks to me as though this pylon is not on the same scale as the landscape it is shown against: the track is about 2.5m wide so the pylon would be 5m tall. Hardly consistent with separations of 8m between conductors of different phases. Scale the pylon
up by a factor of 8 and you would get a very different picture.

An excellent design that draws little attention; compact, blending into the background, and modern without breaking with existing traditions. Yes, please.

I dont liek it there is nothing to draw me to it. It is seams dull.

Kind of OK but boring and so angular... the best of the bad bunch, which however excludes the excellent curving 'sail' design competitor which really is remarkably beautiful for a pylon and gets my seal of aesthetic approval.
Chris B commented on 15-Sep-2011 10:41 AM
For me this design has missed its decade and would have been at home in the early 1990s perhaps. It kind of looks like is has oversized and under-styled ear-rings!
Tracey Hill commented on 15-Sep-2011 10:55 AM
This is my favourite (No. 2). It is the least intrusive and most elegant. I think it's important that the winning pylon design isn't viewed as artistic or 'exciting'. For me, given the amount of pylons across the land surely the intention is to be as invisible
as possible with minimal impact.

I am not aware of the technical challenges when designing these pylons, but is it not an obvious idea to tie in a form of renewable energy capture on these permanent structures? There is not one design incorporating a wind turbine or solar panels. If you
are going to blot the landscape, why not gain something from it too?
Darren J Sage commented on 15-Sep-2011 11:53 AM
This is similar in concept to a Chinese tower - As suspension tower, they are fine, other than the single point of failure as mentioned in earlier comments but when it comes to an angulation
tower, then the Chinese version becomes a cacophony of insulators, additional arms and looks like a pylon pile-up - the risk could be similar with this design. Nice idea though.

Looks ugly like a disused ski lift post

Too industrial, I have imposed it on to assorted landscapes, and it just doesnt work in reality, in our landscapes.
Daniel Brett commented on 15-Sep-2011 02:18 PM
Elaborates on a conventional design and is my preferred entry, although I worry that the dangling "earrings" will blow about in the wind and cause a danger - something that the engineers will no doubt examine.
Grahame Cain commented on 15-Sep-2011 03:39 PM
None of these towers except entry 6 - the lattice tube - take into account the need to be able to found these towers in generally poor ground conditions without massive foundations. A large diamweter base is the best way to disperse the loadings, requiring
the smallest foundations to support the load. What material is this tower made of to make it suitable to support the loads envisaged? An open lattice is the most efficient structure to support the cables and associated wind and snow loads at high level with
the minimum of self loads imposed on the foundation. Any other type of tower becomes impracticable to transport to site, to erect, to provide adequate foundations for, or is not structurally strong enough.

"reduced visual impact" let's face it, it's a massive structure so it might as well be interesting to look at - this isn't.
Johnathon commented on 15-Sep-2011 06:35 PM
Elegant design with the conductors in a triangle. Having two earth wires adds to the cost, could have the earth in the centre instead though.

The authors of this entry made no less than 8 entries into this competition. Multiple entries were not prohibited in the rules, so by exploiting this loophole it appears they have bought their place in the shortlist. Here is the math: £50 per entry fee
£50 per A1 board printing & materials £800 total This does not even include the labour in producing the entries (£1,000's ?)and delivery charges.

Reminds me of telegraph poles. These days it would be called "retro." No provision for maintenance or stability.
TG commented on 16-Sep-2011 07:56 AM
Somewhere someone commented on buildability and cost: also we should consider maintenance and access (encourage authorised, discourage non-authorised). And add the RIBA concern of aesthetics. No 2 should be the compromise which looks OK and which will
be practical.
