An old cable I am not familiar with
Steel braided PVC cables found in an Airey house.
http://wiki.diyfaq.org.uk/index.php/...aireyhouse.jpg Possibly never intended for domestic use and may have been used in pits and quarries is one suggestion I have had. The cables cores are stranded copper and the imperial equivalent of 1mm. Anyone seen it before? -- Adam |

Alternatively, no outer sheathing saved plastic (in short supply) and the steel braiding saved copper (in short supply), and steel (in short supply) compared to conduit, and was quicker to install than conduit.

I was here https://en.wikipedia.org/wiki/Thorpe_Salvin Industrial / mining certainly sounds plausible. Might it even have been for firing explosives? The braiding might help reduce "losses". |

The cables cores are stranded copper and the imperial equivalent of 1mm. Anyone seen it before? As you said an Airey type house. They were built as in kit form including the wiring. Each socket was radially fed with each cable being having different colour pairs. The braiding was the earth return path. -- John Bryan |

Yes when we rewired in the 70s the old cable was mostly rubber with a kind
of fabric on the outside. The cooker supply here is aluminium wire, and it seems to be pretty good, still, but of course dates back to the 60s, and was merely moved to the new CU when the rewiring was done. I've never bothered with another CU to bring it all up to date, since it seems pretty pointless these days. Brian -- ----- -- This newsgroup posting comes to you directly from...

In our last house built 1957 it must have been wired with rubber insulated cable with a separate bare earth conductor running alongside it. I say must have because I only found one section connecting the bedrooms and if I recall right it seemed a lot bulkier than 2.5 T&E. I have no idea what types of sockets were there originally but there was evidence of wires being crimped to the earth conductor. The previous ******s - sorry owners, did a partial rewire if you could call it that hanging individual sockets off the rubber cable with junction boxes and as for the earth simply twisted the CPC from the new sections of T&E onto the old earth no crimps or solder and they did not even clean off the years of crud built up on the wire surface. I do not even to this day know if that section of rubber wire was even part of a ring main. In the end I started from scratch simply ripping everything out.

Coming back to the unfamiliar cable theme I came across a type of cable I had never seen before whilst re-plastering a wall it had two rubber sheathed conductors but they had an outer sheath of lead. It was only a short section I suspect to connect to a wall light. I presume the outer lead sheathing was to provide an earth conductor but it struck me as a very expensive cable especially for the fifties when we had just recently come off rationing following the war! Richard They didn't bother with earthing for lights in those days! Lead was to provide weatherproofing and also to keep ozone away from the rubber, which would otherwise crack. It also means a live to neutral fault should blow the fuse with little risk of causing a local fire. My first house (Victorian) was built with gas lights, but electric lighting was probably added about 1910. This was via wooden trunking with two channels, each containing a single core rubber insulated flex. No two way switching in those days. Still functioning when I moved in (mid 1970's). |

Tricky Dicky expressed precisely :

I say must have because I only found one section connecting the bedrooms and if I recall right it seemed a lot bulkier than 2.5 T&E. That would have been 7.029 old imperial cable. |

newshound was thinking very hard :
This was via wooden trunking with two channels, each containing a single core rubber insulated flex. No two way switching in those days. Still functioning when I moved in (mid 1970's). 'Cap and casing', often installed by joiners who would wire houses up after a bit of basic training, in the 1900's on. |

After all, making a neat job of installing electrics to an old house not built with it needs more joiner's skills than electrical. -- *Cleaned by Stevie Wonder, checked by David Blunkett* Dave Plowman London SW To e-mail, change noise into sound. |
