L6 - Telcontar.net
L6 is a UK electricity pylon (steel lattice transmission tower) series. L6 appears to be the joint tallest tower type in the United Kingdom, with the standard height suspension towers ranging from 49.1 to 50.6 metres tall, compared to 50.5 m for SSE400 .
L6 and L12 have wider middle arms than those top and bottom. They were built for greater capacity than the L2 series. L6 was built in the 1960s, while L12 was its replacement, introduced in the 1980s. The L12 is slimmer than the L6 and slightly shorter, standing at around 46m – whereas the L12 reaches 50m tall.

2022年9月1日 · L6 was introduced around 1960 to provide additional current carrying capacity. L2 could take only twin 400mm 2 conductors as maximum while L6 could take quad 400mm 2. L8 was a replacement for L2, with extended middle crossarms to prevent conductor clashing. Like L2, it will work either at 275kV or 400kV. The current metric version is L8c.

Anti-climbing devices are the barbed-wire assemblies placed around the tower to prevent people from climbing up it. Smaller towers have a single anti-climbing device that runs all the way around. Larger towers (including L2 and L6) more typically have a separate anti-climbing device on each corner for a total of four per tower.

Blaw Knox’s take on L6 is a known exception, where a more arch-like form was chosen. Bracing style is one clue for differentiating L3c from L7, especially in photographs where it’s difficult to assess the tower height. Bracing style is also a clear difference between the numerous varieties of L6 such as Blaw Knox, Balfour Beatty and metric ...
Low height pylons have two main uses: They impact less on the landscape, so are used in areas of outstanding natural beauty . They are able to be used near flight paths as they are less high than other designs .

2022年9月1日 · In the UK we have three common designs, called the L2, L6 and L12. The L2 is designed for 275kV lines, the L6 for 400kV, and the L12 for either 275kV or 400kV lines. The L6 is slightly taller and broader, with a slightly stockier look. There are examples of these in this pdf on the National Grid website. However, there are many more models.

2015年4月9日 · Loved and loathed, the British "lattice" pylon has been built to the same design for 90 years. By Emma Ailes. BBC News. Until the launch of a new design this week, British pylons have been built...
All pylon types have a "standard" height. In some cases they need to be raised, so various height extensions are also available. For example, with L12 series pylons, these come in 3 metre increments and are designated E3, E6 and so on up to E15. (You can also have height reductions, these are designated M3 and M6.)
