A dielectric cable comprising a conductor (10) surrounded by an inner layer (14) and an outer layer (12). The inner layer extends between the outer layer and the conductor in a longitudinally sinusoidal form thereby defining a plurality of closed cells (18) of the same shape. The structure is formed by concentrically extruding the conductor and the inner and outer layers and repeatedly changing the pressure difference between either side of the inner layer. |
