A cable includes a first insulated conductor, a first dielectric tape and a second insulated conductor. The first insulated conductor is twisted with the second insulated conductor with the first dielectric tape residing between the first insulated conductor and the second insulated conductor to form a first twisted pair. The first dielectric tape has at least one strength member embedded therein. A separator may of the cable may also have at least one strength member embedded therein, and serve to separate twisted pairs from each other within the cable.

A composite core for use in electrical cables, such as high voltage transmission cables is provided. The composite core contains at least one rod that includes a continuous fiber component surrounded by a capping layer. The continuous fiber component is formed from a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix. The present inventors have discovered that the degree to which the rovings are impregnated with the thermoplastic polymer matrix can be significantly improved through selective control over the impregnation process, and also through control over the degree of compression imparted to the rovings during formation and shaping of the rod, as well as the calibration of the final rod geometry. Such a well impregnated rod has a very small void fraction, which leads to excellent strength properties. Notably, the desired strength properties may be achieved without the need for different fiber types in the rod.
