Method of and apparatus for making twisted cable and the cable produced thereby |
摘要 |
A method of and an apparatus for making twisted electrical cable, such as 600 volt secondary distribution (UD) cable, and the twisted cable product are disclosed. The apparatus comprises a first plurality of stationary payoff reels each wound with a length of stranded bare wire conductor. The stranded conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the stranded conductors during replacement of spent pay out reels. An extruder apparatus arranged downstream of the accumulator applies a plastic insulation material to a respective stranded conductor as it passes through the extruder. A cooling trough through which water is flowed cools the plastic insulation. A take-up accumulator arranged downstream of the cooling trough accumulates a portion of each insulated conductor during changeover of the take-up arranged downstream of the take-up accumulator. The take-up is rotated about a first axis to twist each insulated conductor about its longitudinal axis and to simultaneously twist the insulated conductors about one another to form a twisted electrical cable. The take-up is also rotated about a second axis for taking up the twisted electrical cable. The twisted electrical cable product made according to the method of the invention comprises a plurality of insulated conductors each twisted about its longitudinal axis by the apparatus of the invention and twisted about one another.
