Abstract
The present disclosure relates generally to a telecommunications wire including an electrical conductor and a dielectric insulator surrounding the electrical conductor. The dielectric insulator defines a plurality of channels defining void space containing a material having a low dielectric constant such as air. The channels each run along a length of the electrical conductor. The channels are configured to lower an overall dielectric constant of the dielectric insulator while maintaining desirable mechanical properties such as crush resistance.
