摘要： A method of and an apparatus for making twisted electrical cable (T), 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 (32) each wound with a length of stranded bare wire conductor (C). The stranded conductors (C) are simultaneously payed off the reels (32) to a pay out accumulator (34) for accumulating a portion of the stranded conductors during replacement of spent pay out reels (32). An extruder apparatus (36) arranged downstream of the accumulator (34) applies a plastic insulation material to a respective stranded conductor (C) as it passes through the extruder (36). A cooling trough (42) through which water is flowed cools the plastic insulation. A take-up accumulator (20) arranged downstream of the cooling trough (42) accumulates a portion of each insulated conductor during changeover of the take-up (28) arranged downstream of the take-up accumulator (20). The take-up (28) 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 (28) is also rotated about a second axis for taking up the twisted electrical cable. The twisted electrical cable product (T) made according to the method of the invention comprises a plurality of insulated conductors (50) each twisted about its longitudinal axis by the apparatus of the invention and twisted about one another.

The conductors (C) are simultaneously payed off the reels (32) to a pay out accumulator (34) accumulating a portion of the conductors during replacement of spent pay out reels (32). At least one extrusion (40) process arranged downstream of the accumulator (34) applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process (40). A cooling and/or curing through (18) through which water is flowed cools and/or cures the plastic insulation. A take-up accumulator (20) arranged dowstream of the cooling and/or curing through (18) accumulates a portion of each insulated conductor during changeover of the take-up reel (28) arranged dowstream of the take-up accumulator (20). The take-up reel (28) and (24) may be rotated.
