Patent ID: 8022302

Claim:
A telecommunications wire comprising: an electrical conductor; and a dielectric insulator surrounding the electrical conductor, the dielectric insulator defining a plurality of closed channels and a plurality of open channels, the closed channels and the open channels defining void space containing a gaseous material, the closed and the open channels being circumferentially spaced about the electrical conductor, the closed channels and the open channels each running generally along a length of the electrical conductor, and the closed channels defining at least 75 percent of the void space, wherein the dielectric insulator includes an outer circumferential wall defining an outer diameter of the dielectric insulator, an inner circumferential wall spaced radially inwardly from the outer circumferential wall, and a plurality of radial walls that extend between the inner and outer circumferential walls, wherein the closed channels are defined between the inner and outer circumferential walls, and wherein the inner circumferential wall, the outer circumferential wall and the radial walls each have a thickness in the range of 0.001 to 0.0035 inches.
