ABSTRACT:
For SZ twisting power cable conductors with a sector shaped conductor cross section which are not pre-twisted, two twisting heads are used which form a stretched accumulator and are arranged, respectively, after or before a twisting closer and revolve synchronously with changing rotary motion. Ahead of the first twisting point, a positive guide is arranged for each cable conductor. The positive guides and the twisting heads are arranged at a distance as short as possible from the twisting points. In this manner, an exact twisting geometry of the twisted assembly in the vicinity of the reversal points of the twist direction is obtained.
