<div>It now makes a lot more sense. However, the word
"isolated" is present twice in the rationale. </div>
<div><br>

<div>You probably ought to mention something that was brought
up on this list: that some power</div>
<div>lines have a cladding which is not considered to be an
electrical insulator. It is unlikely most</div>
<div>mappers could tell the difference.</div>
<div><br>
</div>
<div>Yes, there are insulated cables. They're present on
minor power lines for local distribution (they</div>
<div>run along streets with feeds to houses along the street)
near me. At some points the line<br>
</div>
<div>between poles is a single insulated cable and at other
points along the same street it switches</div>
<div>to four, physically-separated, uninsulated conductors.
It appears to me that the uninsulated</div>
<div>stretches are older than the insulated ones and that as
repairs become necessary they change</div>
<div>to insulated cable. I suspect that on anything other
than this type of local distribution any covering</div>
<div>around the wire is cladding rather than insulation.</div>

This may be true for local low voltage distribution in your area. <br>
<br>
In my residential area low voltage distribution runs insulated from
the power pole to the residences, but uninsulated from power pole to
power pole. <br>
<br>
-----------------<br>
High voltage (10s if not 100s of kilo volts) run uninsulated here
and I'd think that would be true anywhere. <br>
