Abstract
Treeing is suppressed in cables through the use of an insulation layer that includes a polyolefin polymer and an additive with delocalized electron structure. The additive can be a carotenoid, carotenoid analog, a carotenoid derivative, a conducting polymer or a combination of two or more such materials.
