Abstract

The telecommunication cable with plastic insulated conductors has a filler for longitudinal sealing of the cable against water penetration. The filler may be non-polar, foamed-up and reticulate bonded by a high frequency process such as by passage through a UHF cavity resonator. The filler can be applied to the individual conductor before twisting or in the case of a cable with multiple twisting stages can be applied before the consecutive twisting process on to the twisted element. Due to the reticulate bonding favourable elastic properties are obtained and by the foaming-up of the filler the dielectric constant is reduced which results in an improvement of the overall transmission properties of the cable.
