Abstract
A telecommunication wire having an electrical conductor is surrounded by an insulator. The insulator includes a main body made of a first polymeric insulator material. The main body defines a plurality of channels that run generally along a length of the electrical conductor. Each channel includes a first region and a second region. The first regions are filled with a second polymeric insulator material having a dielectric constant that is lower than the first polymeric insulator material. The second regions are filled with a gas such as air.
