    摘要: Method of making a twisted conductor wire unit in which each wire of the pair is individually insulated. The twisted pair is provided with an outer extruded polymeric layer while a vacuum is applied to the pair at the extrusion position. The vacuum draws the polymeric layer down onto the pair and forces the insulated wires together along the length of the unit. The vacuum is insufficient to produce substantial longitudinal indentations in the polymer layer. This avoids spaces being provided between the insulated wires in the finished structure and provides a substantially constant distance between the wires to improve electrical and cross-talk characteristics.
