Abstract:
A wire comprising a conductor extending along a longitudinal axis, an insulation surrounding the conductor and at least one first channel in the insulation extending generally along the longitudinal axis to form an insulated conductor, the at least one first channel containing a gas, wherein an outer peripheral surface of the conductor forms one side of the at least one first channel, wherein the insulated conductor has at least one property selected from the group consisting of:a) invasion of substantially no water after submerging the insulated conductor for 30 days in water heated to 90Â° C.; b) retention of more than 75% of the cross-sectional area of the at least one channel when a 12 inch length of insulated conductor is twisted 180Â° about the longitudinal axis of the conductor; c) retention of more than 75% of the cross-sectional area of the at least one channel when a 12 inch length of insulated conductor is twisted about another insulated conductor; d) variation of less than 0.05 of the dielectric constant of the insulated conductor between before and after a crush strength test.
