Abstract
This is a prf'sentation of thP m'lin d<>sign and
construction features of a double circuit line at
132 KV, using new concepts in compactness of
supports and in the gf'ometry of the phases.
Amongst other things, this makes for much smaller
pylons and a much sma 11 er right of way for thf'
line.
One of industry's main worries nowadays is the
degradation of the environment in all its aspects
(pollution, deforestation, visual impact, rights
of way, etc). This is even more important near
big cities.
The design and construction of a high-voltage
power 1 ine is aggressive to the environment, and
the aggression is hard to avoid because the very
function of the 1 i ne - to take power from onP
p 1 ace to another - means it is not confined to a
particular site.
The length of the line we shall be talking about
here is not excessive (2.338km), but the land
through which it must pass is near highly
populated urban consumption areas and also near
an airport, which has its own rights of W·'Y
These factors contributed to the der.ision to
minimize the aggression to the ~errain, reduce
rights of way and make the line visually
pleasant. All this was aimed at dealing with the
difficulties which we assumed we would be faced
with.
We further attempted to include the latest
designs in the supports and the configuration and
layout of the phases, with rotary crossheads
based on composite insulators to give a slimline
look.
