I was on the two biggest in the uk. The Thames crossing and the Tyne crossing.
The Tyne crossing is over 1000 feet and the Thames crossing is 890 feet.
I must admit I was out of puff doing the fibre optic wrapping on the Tyne crossing.
We did an inspection on the Thames crossing .
Pic one the Tyne
Pic two the Thames

Be safe Max,dont eat beans the night before in case of an emergency....and Bren I almost posted that those towers aint no 1000 feet high....glad I didnt.....1000 feet between spans,Ill buy that.

Got mixed up Reppy.

Here's the FACTS.


The 400 kV Thames Crossing is an overhead power line crossing of the River Thames, between Greenhithe Marshes in Swanscombe, Kent, and West Thurrock, Essex, England. Its towers are the tallest electricity pylons in the UK.[citation needed]

Detail of the Kent Tower
The present crossing was built in 1965, and comprises two 190-metre (623 feet) tall lattice towers either side of the Thames. Some suggest that the choice of this height was deliberate, being just taller than the BT Tower in London.[1] The span is 1372 metres (4501 feet), the minimum height of the conductors over the river is 76 metres (249 feet). Each tower has three crossarms and carries two circuits of 400 kV three-phase AC.

Thats pretty much up there,623 feet ...the highest in my area is about 300 feet crossing the ship channel,dont know the lenght of the span though.

I'm about 20 miles north east of the Essex one. Pass it quite often on my travels.

Bren, they are currently restringing the line from Rayleigh grid down towards thurrock to supply the new port at Coryton.

Balfours are doing it with more plant than you can shake a stick at. If it get a chance I'll get some pictures

Cheers stu.
I used to work with the national grid Kent line gang... Still talk to them now an then....
We used to work out of Northfleet... They still do. They will be doing quality control and safety checks on Balfours.

[U]mm on them long spans are they double deadended on both sides of the crossing?

This is the Kent side Poot ...

Think this might answer your question. :)

[reppy007]

That lower phase on the closest tower looks mighty mighty low....1 violation for you Mr.Bren :mad:

[Pootnaigle]

Ummm lottsa insulators for one conductor

Its called over-kill Poot....never seen nothing like it here in the states .

What size wire? Right now my shoulders and arms are hurting just thinking about the hoist and rigging you would have to put on. And then you would probably need a crane just to get the press head. What would be the tension for a two mile span? Looking at that looks like a lot of work. Just a string of bells is probably 2000 pounds. And what I dont get is America still uses english weights and measures and the canadians and english use kilometers. Are we the only country in the world that doesnt use the metric system?

Not sure of the wire size... But not much hand pulling .. Rigged to the winch they pull the wire to tension then fix a block on the wire and winch the insulators towards the pressed gun ends.
Funny to see the bells on a terminal tower facing that way due to the height of the adjacent tower.

It's all metric now. Except the UK still use miles per hour.. Every where else it's kilometres
( including Ireland ) .... I did once get a measurement from a foreman in the uk. He told me the downleads into a substation were 22meters and four inches. :eek:
