ABSTRACT:
Insulated electrical conductor for telecommunications cable in which two layers of insulation are provided. The inner of the two layers is a solid non-cellular construction and the outer layer is cellular. The nominal mutual capacitance between the conductor and an identical conductor is at a desired nominal value of 83 nanofarads/mile value between conductors above a desired minimum value while having an outside diameter across the insulation which is less than for a conductor of the same gauge which provides the same mutual capacitance and has a solid insulation of the same material as the inner layer.
