I need some help. I got this power cord that has been twisted around a pole
for at least a couple of years. When I tried to un-twist it, the cord would
not comply (which is not surprising since it has been wrapped around this
pole for years). My question is, how do I get the cord to un-twist and if
that is even possible, can I still use it?

I hope this is the right newsgroup to post this too. If not, please give me
advise on where this posting might go.


Thanks for any help!!

maybe a little heat gun or even hair drier might soften thing up a little.
don't over do it though. if the cord is damaged consider writing it off and
throwing it away.

insulation is damaged. buy a replacement.

You should never use a power cable when coiled - it acts like an inductor
and heats up. Hence the warning on drum extension leads about always
extending them fully. Sounds like you've used it at high current (for that
cable gauge) and melted the insulation enough for it to re-form to that
shape.

I have no experience with this, but couldn't your reel be melted due to too
much current on too small of wire rather than being wound up?

A lot of times what happens is the coiled up cable can't dissipate heat
as it can if it's stretched out along the floor. The induction might
have some effect, but an air core inductor at 60Hz in series with a load
won't have much effect.

If the cord cannot be flexible, then it is dried out, and is probably no
longer safe. It would be best to cut it off, and have the power cord in your
appliance completely replaced.

Many of those use #18 AWG cable, not so surprising if melting occurs.

Almost the same reason as why wet hay will start a fire.

The inductance of a coiled AC line cord is the same as an uncoiled cord.

Because the net current in the coil(s) is zero, and therefore the
magnetic field is zero?

Yep. Trace the current flow for a complete circuit and you'll see that
for every turn in one direction, there is one in the opposite direction.
