Repair 100 foot length extension cords

May 31, 2022 Last reply: 4 years ago 17 Replies

When I repair long extension cords I put those thick leviton or starelo plugs on each end and usually I cut them at where there is wire showing.



But I hate to cut a hundred foot length into four 25 feet lengths.



The reason is in many cases it's just the casing and not the wires which are cut (usually from bending around sharp objects) such that they "can" be saved perhaps?



Assuming the copper conductors aren't showing, what do you use to repair extension cords that's better than just duct taping them at those breaks in the outside sheathing?



Is there something made for the purpose that can be used like maybe heat shrinking something on that doesn't require the connectors to be removed?


I think tape is about as good as you can do, eg black electric tape which is easier to work with than duct tape. If a 100 ft one is compromised in four spots, probably time to toss it.

Extension cords or garden hoses - 50 ft. works for me. ... the longer lengths are a pita to roll up. John T.

Silicon tape, at least that is one name for it. It may have other names.

If it doesn't work this way, it's not what I mean. You stretch it quite a bit as you put it on, you partially overlap multiple layers, and after a couple days, it merges into one big blob. AFAIK, they never come apart.

I even took one that was cut, soldered the wires together, wrapped each conductor whose insulation was damaged, then wrapped the whole thing. Works fine.

I need about 100 feet to reach to my back yard with the lawn mower or to reach the parking lot where my car is. But I don't roll it up either. It just lies in the grass for the last 8 years, in the rain, under the snow, whatever. it may have tripped the GFI once or twice, but maybe that was something else.

The garden hose I roll up but my 39 year old reel is rusting and I don't like any of the replacements.

I call that self vulcanizing tape. I haven't had good results with it, maybe I had an old roll.

I don't know if they contain much silicon or not. Aother thing to tell if you have the right stuff is that it has a backing tape, which is hard to seaparate from the tape, but it can be done.

And it's expensive, but worth it.

Apparently they added an e to the end of the name to make it harder for me to find. Why is everyone against me?

Self-fusing is another good word that goes with it.

I just get 1" wide, like electric tape.

This might be it,

it says easy to remove. less than 1/3rd the length of the first one but less money too.

Silicon is an element. A metalloid. Similar to a metal. Silicone is a rubber. A polymer. Nothing like a metal.

Yes, but when I bought it 10 years ago it was called silicon tape. Now it's called silicone. I don't know why, but there are a lot of e's in this world and some need a good home.

I'm old school so I'd go with rubber tape covered with vinyl.

I would choose Door #1, the ethylene propylene rubber tape with an overwrap of vinyl. It's also self-fusing but the 360 degree F rating of the silicone tape is overkill.

We used a lot of it when I was in jet aircraft maintenance in the USAF. I never had a problem with it.

I never liked it when people say "silicone" when they mean silicon. In this case it appears "silicone" is the correct word. i don't know why it was called silicon.

One of these e-problems is when people mix up "breath" and "breathe". That really happens a lot (and not just on the internet).

Only by loosers.

Silicone was never called silicon and vice versa. Anyone who says either was the other is a doofus.

Silicon is a mineral used in semicondictors and steel alloys.Brittle and blue. Silicone is a polymer made of siloxane. Neither should be mistaken for slica - which is a compound of siicon (actually an oxide) - better known as quartz and a major component of sand (and glass)

Who don't care about the unwanted superfluous extra 'o' that doesn't belong there.

Probably so, This was the first time I even heard silicone called silicon, although I have heard silicon called silicone. As to the "doofus" part, probably so.

Then there were the valleys:

- Santa Clara Valley is the Silicon Valley. - San Fernando Valley was the Silicone Valley.
