Polyolefin wire insulation in hydrocarbon grease filled telecommunications cable which is subsequently exposed in an outdoor interconnection box is especially vulnerable to the adverse conditions of heat, oxygen and moisture . The combination of one or more primary phenolic antioxidants selected from N,N'-hexane-1,6-diylbis-(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionamide), tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate and tris(2-(3,5-di-tert - butyl-4-hydroxydrocinnamoyloxy)ethyl)isocyanurate together with one or more alkyhydroxyphenylalkanoil hydrazine metal deactivators is very effective towards providing oxidative stability for polyolefin wire insulation under these conditions. |
