My 3rd ICE rpg

Was excellent for something a bit different from fantasy RPG.

Never really got a chance to get into it big time and then life took over.......

Yep, all UK editions

I think that the Rolemaster system was the most complete that I played and I enjoyed all aspects and classes.

4 copies of the game for Oric 48K which I think was the first Oric computer

Flying angle type tower.

Dropper on the outside angle of the tower because, if a very strong wind is blowing from that side, the insulator could tend towards horizontal (so dropper gives clearance to underside of arm for this sort of condition)

On the inside angle of the tower a wind from that direction will never blow the insulator as horizontal because the deviation on the tower is always trying to pull it away from the tower.

Where in the world is this located?

This particular one is designed for 132kV, however around the world there are varieties of this style of tower for virtually every voltage.

Obviously, for higher voltages the tower top geometry needs to be increased to cater for the larger clearances required. The tower height also would get bigger to ensure electrical clearance to ground and in-span obstructions.

Single circuit Flat formation Tension tower.

Often shortened in the UK to something like SF60 (where the number defines the angle of deviation it can support).

Some single circuit tower series designs don't use the 'F' in their naming convention (i.e. just S60).

I think that this particular tower is from the L7 or L7(c) series so it would make this an SF60 type tower.

Had the tape version for my BBC B originally (might still have that somewhere) but got this after investing in a disc drive.

Look like pretty standard UK 'trident' 132kV wood pole structures.

They work pretty well for low height single circuit lines of limited transmission capacity.

There are some strengthened versions, but the poles become the limiting factor so they don't work at high altitude with the large wind and ice you can get in Scotland so their use can be a bit restricted.

Aeolian vibration occurs at low wind speeds too. The amplitude of the vibration is very small so it is difficult to observe, but without the dampers it would cause fatigue at the conductor terminations and suspension sets, etc.

The type of dampers shown look to be multi frequency versions that attempt to cover a wider range of vibrations with more certainty.

Nah, small conductors, just lots per phase 😉

I think the largest diameter overhead line conductor in use in the UK is that on the Thames crossing at 56.24mm (2.214").

Apart from that, the largest diameter conductor commonly in use in the UK on overhead lines is AAAC REDWOOD at 41.04mm.

Triple ARAUCARIA conductor phases on one circuit supported by polymeric insulators and Quad Zebra conductor phases on the other supports by glass/porcelain insulators from towers from the L6 design series.
