Default Equipment mains cables, flex etc

Having brought my old Tape Recorder out of it's hibernation, I was once again surprised at the flimsiness (?) of the mains cable, it seems that almost anything would be used in olden days, I remember my wife had a table lamp many years ago which had what looked like speaker wire from new, single insulated..

What strange cables or flexes do you have on your old equipment then?

Hi,
Here's the pink mains lead on my Hoover Constellation vacuum cleaner. I think it's great that they colour co ordinated the lead to the machine.
Cheers,
Des.

That's like a Barbers pole. My constellation has Flymo orange cable ... I needed more range.

single insulated wire was common in the 60s .Plastic ,either white or clear ,twisted ,or straight side by side .We has it t home .It was also used in my parents 60s house and still is for the light pendants from the ceiling rose to holder .I think it was used for table lamps lighting etc and wasnt meant for anything else .I have come accross that weedy grey stuff on things like tape Reel to reel machines too

I well remember the clear plastic twin flex, which was used extensively in days of yore.

The flimsy twin flex leads for shavers and some battery/mains transistor radios still currently on sale, which are terminated in a barely adequate figure of 8 plug, are none to clever either, and often go open circuit due to flexing at the appliance end.

Ironic that the 13A wall sockets into which these things are connected at one end are shuttered to prevent metalic objects being poked in, and the neutral and line pins of 13A plugs have for some years been shrouded half-way, yet these figure of 8 jobbies have open ends, which pose a danger.

Anyone who has a fairly new Hotpoint or Creda washing machine will notice that the flex is thinner than on older machines, which would use 1.25 mm or 1.5mm. I'm told it is just the insulation that's thinner but I'm not convinced. I've had dozens of Dyson vacuum cleaners come in for repair with bare wires exposed where the flex enters the machine. I notice when working on old equipment that the pvc insulation is much more difficult to strip and have wondered if the modern stuff is made flimsy due to cost cutting in manufacture.

My father who was registered blind for the last 20 years of his life did manage to get a shock from a shaver cable that got damaged.

When I moved into this, then newly built, maisonette in 1966, the light fittings were all wired with cotton covered twisted pair flex from the ceiling roses to the bulb sockets. AFAIK this type of flex was in common use for light fittings back then. Anyone know when it's use was discontinued?

Guessing relatively recently, if at all? When I worked for British Steel (thirty years ago) the same flex was about, a burgundy-coloured cotton covering, but the cores were brown and blue - so must've been upgraded for the new colour codes.

Thats interesting I thought it had been superseded by the clear plastic twist stuff by the 60s for house fittings .Was it rubber or plastic inside? The later type angle poise lamp that was very common in most houses in the 70s , I have seen with variations of switch etc ,and one ore two including one i have was fitted with rubber cloth covered flex i assume it was an early version ?

Rubber, as I recall. I used a length for a morse key for a while - may still have it somewhere! I'll photograph it if so. It won't be the same perishable rubber as was used on the older stuff though.

There is still available a reproduction cotton-covered twisted 2 and 3 core pvc insulated mains cable available for the more upmarket appliances, it's in the european harmonized colours and under the cotton is pvc. It's very expensive!

You could still get figure-8 table lamp flex well into the 70's from Woolworths etc.

It's still common in the US and sometimes comes in on grey-imported appliances that are dual voltage; I doubt they'd get approval here so should be changed by the dealer.

It may still be the perishable rubber. Light rose fittings still looked attractive up to the late 60s .I wonder when they brought in the boring plain rose instead of the ogee shaped one? There was one later one , fitted here with ribs on the ogee. I forgot in my house upstairs are still a couple of roses with pendant fitting ,circa 1962 .They have plastic cable though.
That American link is very interesting ,They are good at reproducing things well .I have seen good stuff in
the way of reproduced house fittings , much better than we do here.

Dug out this from the junk box, flex fitted with 2 pin plug. Also in shot 2-way adaptor with sockets for a much smaller 2pin plug and a bayonet to 2pin adaptor.
