Abstract
The disclosed communications cables have tensionproof jackets which consist of tensionproof and axial-compression-resistant tape and an outer plastic covering extruded over the tape. The tape includes lengthwise threads of aramid or glass, lengthwise threads of aramid- or glass-fiber-reinforced plastic or a liquid-crystal polymer, and cross threads of a different plastic material. It may be designed as a open-mesh tape. The tape has a longitudinal seam which may deviate in alternating direction from the longitudinal axis of the cable by a small angle to improve flexibility.
