Abstract

A co-axial cable has a conducting core (10) and surrounding layer or layers of insulation (12). A layer of material (11) is provided between the core (10) and the insulating layer (11) which prevents distortion at high temperature due to thermal expansion. The layer (11) prevents distortion either by melting to form a lubricating layer, or by acting as a physical barrier to distortion. The layer may be made of polyethylene, polypropylene or polybutene or may be glass fibre tape with mica platelets. A screening layer 14, preferably copper braid, is arranged around the insulation.
