Crush resistant conductor insulation
First Claim
1. A pair of conductors each having polymer insulation thereon, the polymer insulation on each of said conductors having an exterior surface comprising:
- peaks and valleys alternating longitudinally along said exterior surface, said pair of conductors each having said polymer insulation thereon being twisted together to form a twisted pair wherein at least one of said peaks in the exterior surface of said polymer insulation on one of said conductors is nested in one of said valleys in the exterior surface of said polymer insulation on the other of said conductors to provide an improved impedance efficiency as compared to polymer insulation of the same weight but of uniform thickness.

Abstract
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.
