Description
Description
CCT covered conductors have a specified thickness of covering for each of the nominated working voltages. While still required to operate under similar principles to a bare wire or CC system, they have electrical and mechanical characteristics which permit them to remain in contact with tree limbs for an extended period dependent on abrasive characteristics of the tree, frequency and strength of prevailing winds and operating temperature. CCT show better performance in polluted environments. They are suitable for use in 'spacer cable' systems and in the insulated unscreened conductor (IUC) systems.
