摘要： A Communications cable is provided comprising a conductor and polymer insulation encasing said conductor, the polymer insulation having a foamed interior and having an exterior surface formed from longitudinally running rounded peaks and valleys. A process is also provided for producing this polymer insulation or unfoamed polymer insulation having the same or similar peak/valley exterior surface by extruding molten thermoplastic polymer through an orifice to coat a conductor passing through the orifice, thereby forming polymer insulation on the conductor, said orifice defining the exterior surface of said polymer insulation comprising longitudinally running rounded peaks and valleys, said peaks covering at least about 30% of said exterior surface and having a height that is at least 50% of the width of said peaks.

摘要： A process of twinning a pair of polymer-insulated conductors to form a twisted pair, where the polymer-insulated conductors are formed by extruding a uniformly thick coating of polymer onto the conductors. More than one twisted pair is encased in a polymer jacket forming a cable. The twisted pair obtains a desirable average impedance performance using a reduced amount by weight of polymer forming said polymer-insulated conductors by: (i) extruding to form longitudinally running peaks and valleys in the exterior surface of each of the polymer-insulated conductors of the pair of polymer-insulated conductors and (ii) twinning resultant polymer-insulated conductors to nest at least one of the peaks in the exterior surface of one of the polymer-insulated conductors in at least one of said valleys in the exterior surface of the other of the polymer-insulated conductors of the pair of polymer-insulated conductors.
