Abstract
Novel additive systems for metallocene based filled cable insulation are disclosed. These systems provide excellent protection against thermal degradation, better cure state and reduced dissipation factor after prolonged heat exposure. The additives may contain one or more hindered amine light stabilizers and amine antioxidants.
