Around Blyth - ID help please...

[lesc]

Everyone -

An hour travelling to and around the south of Blyth got me these -

L2's near Holywell march up beside a railway line -

L2 Deviation Tower:

Standing on the tracks gets me this:

Around Blyth, just off the A189 gets this L2 on 275 and an L4(?) on 33KV -

Pylon detail:

This is also the other home of the L66.

Not far away from the previous gets these - L66, PL1b or PL4 or PL7 or but deffo not PL16 AFAIK on 33KV single circuit and some poles.

Detail of unknown PL___ pylon type 33KV double circuit:

Decidedly old, chunky and 1st time ever seen a double circuit PL1 D30 and off they march. L66's in distance.

A real mixed bag: unknown PL's, L66, L2 and poles. The birds are rooks.

Are the 2 conductor poles (shown in P3060946.jpg) carrying railway traction power to a nearby railway line?

Possibly, the East Coast Main Line isn't a billion miles away!

Thanks for more great photos, good examples of the differences of height between different designs.

Let's see if I can help on identification...

The one on the right is an L4(M) (upturned crossarms with no bracing on the vertical faces of the crossarms is the giveavay for these). 4 insulator elements suggests it may be 66kV. Need to look at the Northern Electric route map to find out.

I don't know what the tower type is, but it's not a 132kV design. Notice that the conductors hang about half way between the crossarms rather than well above the middle of the gap as the do with the L4 above. I think this is 66kV and these are designed as 66kV towers.

Same comments as above. I did some very nasty things to this image in Photoshop, but I can't quite read the safety information on the signs. I can tell that it's tower number 34, but that doesn't get us far!

We're still in 66kV territory, but a Pl1 angle does look quite similar to that. The difference is that being 132kV, the Pl1 is substantially bigger and it has an even less well defined tower peak than this one - they really didn't seem to care about keeping the earthwire high on the angles.

Answering blueshift's comment on this, the poles aren't 2-phase ones at all, they're a very odd 3-phase design. The wire that looks as though it should be an earthwire is the middle conductor on upstand insulators at the tops of the poles. I think that in this example the insulators are plastic, which is why they look a little undernourished in comparison to the ceramic suspension sets.

This design of pole seems to have been a Northern Electric special (and possibly NEEB before it) for 66kV. Tom Routledge, their top transmission guy in the early 90s didn't like Trident poles and wouldn't use them, preferring various locally-developed alternatives for 66kV and 132kV.

I've added a couple of them full sized! Please download these if you really want to but please be aware I host these at home and my upstream is 768K!

Again, Dr. Fortran - exalted for superior knowledge

A good pic in itself - mystery 33/66KV pylon - left circuit is 'EWK', right circuit is unknown disappeared in a pile of 1930's rust?

Tweaking file in Irfanview / Gimp / PSP reveals nothing on the plate. Caution it's a *big* file.

2nd one - from the tower bible I thought this was all the world like a Milliken PL1 D30 apart from the spacing between the centre and top. The birds seemed to like it. Caution *big* file and little bandwidth.

Pics were taken at Hartford, near Blyth from a road that said 'NO TRESPASSING' at its entrance, copy and paste below for exact location it's the dead end that goes off on its own
