Some people collect stamps, I collect cable. Preferably as short encapsulated paperweights, although I do have others, such as a piece of TAT1 and a piece of the original transatlantic telegraph cable of 1866.
One of my paperweights is a 6-core lead covered cable, each core 0.125 sq. inches copper rated at 11,000 volts WP (which I guess is Working Pressure which translates to Working Voltage) It was produced for the City of Sheffield by the Western Electric Company London. No date given.
Why use a 6-core cable? Seems to be putting all ones eggs in one basket if used for a two circuit system. Had it been for a lower voltage, then perhaps an ac feed to a mercury arc rectifier, but surely not at 11 kV?
