RELIEF SIGNALMAN Posted August 22, 2019 Share Posted August 22, 2019 Speaking to my cousin earlier regarding the time he worked for the National Grid he was telling me that there are plenty of PL1S pylons around the Warrington area which he worked on during his employment between 1970-2000. They refurbished quite a lot in the area including the two giants over the MSC by Acton Grange Junction few years ago. He also got called out to attend to a failed pylon sinking in the marshes at Stafford Common about 20 years ago. Some of the PL1S pylons along the marshes there (North of Stafford) were in a condemned state due to their age I suppose, even the insulators were not free to swing with the cables and the metalwork had seized up altogether. When he got there the pylon was leaning over at 30 degrees and a substitute temporary single tower had to be erected on a concrete block with loads of stay wires to carry the cables way from the sinking pylon. The condition of the line in that area was actually really bad and they decided to scrap it as they found another pylon starting to lean and the concrete feet had completely disappeared below ground. The rest of the line into Stafford itself was kept and modified including the same line that crossed the WCML just north of Stafford station. Have anyone here got any photos of these temporary single tower mounted on a single concrete block?. Reminds you of a lattice crane jib in the vertical position. 1 Link to post Share on other sites More sharing options...

Key differences are the tower peaks, the D60 has a flat peak with angled sides whereas the D40EC has a pointed peak like a D30. Also the D60 has pointed crossarms on the inside of the turn and square ended crossarms on outside, the D40EC has square ended crossarms on both sides of the tower. D40EC intended where circuits split away from the centre line usually on the approach to substations like this one. Cheers Paul Link to post Share on other sites More sharing options...

I know it’s of a Balfour Beatty design and I know it has traits of a D60 but I want to know if it’s a special type of tower. There is another type of this at another substation (name I have forgotten) that has a similar design too. First photo looks like an L6 equivalent of the L2 D40EC tower I've just described. Second photo looks to be a L6 D60 maybe Blaw Knox not got my info handy right now. Cheers Paul Link to post Share on other sites More sharing options...

Cheers Paul They are both Balfour Beatty L6s and the second one is doing the same thing as the first, the only reason I said they are the same is because they have pointed tops, compared to the flat top on a standard D60 Link to post Share on other sites More sharing options...

LMS_LNER_SR_GWR_fan2004 Posted August 23, 2019 Share Posted August 23, 2019 So that means that the L6 at Burwell is a L6 D40EC, so is there a plan for them or is it just a mix and match of other plans..... This might require another email to national grid asking? Link to post Share on other sites More sharing options...

My guess for this is that the PL16 line (the smaller pylons) was built first but when the L2/L3 pylons came about later they had to split the line and divert it underneath using those smaller pylons. I’m not an expert I just like these things so I might be wrong in a couple of places but someone will correct me. HTH, Matthew Link to post Share on other sites More sharing options...

Cheers Paul Yes it does indeed, I thought the same thing. It's the JL EVE variant of the L6 is the one you mean. (Edit): Just found out why they are so similar, the L13 is designed by Babcocks who are JL EVE.
