Abstract
A pull-in head for a high voltage cable provided with a multi-wire conductor having an end portion which is stepped and tapering, with a layer-by-layer exposure of the wires in the direction towards the end face of the multi-wire conductor, wherein the pull-in head includes: a conductor clamp assembly having a plurality of clamping segments, wherein each clamping segment has an axial first central channel configured to receive the multi-wire conductor, wherein at least some of the clamping segments have mutually differing central channel width and central channel depth dimensions, the clamping segments being configured to be arranged one after the other in an order with a decreasing central channel width and central channel depth dimension, the central channel width and central channel depth dimensions being adapted to the tapering stepped configuration of the multi-wire conductor, whereby the first central channels together form a multi-wire conductor channel which is tapering in an axial direction, and wherein each clamping segment is configured to provide individual clamping of the multi-wire conductor, and a hollow lifting head configured to receive the conductor clamp assembly…
