<p>A ribbon cable or discrete wires, having a layer of thermally stable, crush resistant, fibril microporous heat sealable thermoplastic crystallizable polymer dielectric surrounding said conductor. The thermoplastic dielectric having a void volume in excess of 70 %, a propagation velocity of the insulated conductor greater than 85 % the propagation velocity in air and the crush resistance being the recovery rate of the material after being under a 500 grammes weight for 10 minutes greater than 92 % of the initial thickness.</p> |
