I came across an old cable yesterday (apparently installed decades ago), supplying communal lighting (5 * 16W 2D's) in a block of flats, and haven't been able to determine what it is, so any ideas please.
It's circular, white sheathed, has 3 solid (1mm2) cores (red, black and un-insulated annealed copper), and has what appears to be cotton strands running the length of the cable inbetween the cores (took a picture but mob then died without saving it, and I can't get back in the building yet to take another). Cable is concealed in lathe and plaster walls, with only short bits of sheathing protruding/showing (same at rear entry to the CU), so can't determine the manufacturer's name on the sheathing. Wondered if it's some sort of old fire rated cable. Spent a couple of hours on the blower this morning, describing it to Prysmian, Eland, etc, but nobody has a clue what is is.
Any help appreciated.
