Abstract
A cable (20) which may be used for communications, for example, include transmission media (24-24), each having a plastic composition of matter disposed thereabout. The insulation (26) comprises a polyvinyl chloride composition which includes a lubricant and a lead-free stabilization system. The stabilization system includes a calcium-zinc constituent in combination with an antioxidant-metal deactivator complex which provides a sacrificial function to prevent the formation of calcium or zinc chloride which would affect adversely the electrical properties of the insulated conductor. A jacket (28) typically is disposed about a plurality of the transmission media and comprises a non-lead stabilized plastic composition of matter.
