Abstract (en)

[origin: WO0011680A2] A method of an apparatus for making twisted electrical cable (T), such as 600 volt secondary distribution 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 bare wire conductor (C). 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.

The conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the conductors during replacement of spent pay out reels. At least one extrusion process arranged downstream of the accumulator applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process. A cooling and/or curing trough through which water is flowed cools and/or cures the plastic insulation. A take-up accumulator arranged downstream of the cooling and/or curing trough accumulates a portion of each insulated conductor during changeover of the take-up reel arranged downstream of the take-up accumulator. The take-up reel may be rotated about a first axis to twist each insulated conductor about its longitudinal axis, and may additionally simultaneously twist the insulated conductors about one another to form a twisted electrical cable. The take-up reel may also be rotated about a second axis for taking up the twisted electrical cable.
