MEDIUM VOLTAGE CABLE INSULATION

摘要

Compositions comprising:
A. 10-99 wt% Ethylene-based polymer;
B. 0.1-1 wt% Polyalkylene glycol;
C. 0.1-1 wt% Tertiary hindered amine stabilizer;
D. 0.1-1 wt% Sulphur-containing hindered phenol antioxidant;
E. 0.1-3 wt% Peroxide; and
F. 0-1 wt% Coagent; in which the sulphur-containing hindered phenol antioxidant is a thiobisphenol, are useful in the preparation of TRXLPE insulation for medium voltage cable that exhibits a commercially desirable balance of long term heat aging retardancy and water-tree resistance.
