Claims18
An insulation compound for a medium-voltage power cable, comprising:
- a polymer comprising ethylene and one or more C3-C8 alpha olefins;
- and
- one or more metal sulfides.
An insulation compound for a medium-voltage power cable, comprising:
- at least one elastomer comprising ethylene and one or more C3-C8 alpha olefins;
- zinc oxide;
- and
- from 1 to 10 phr zinc sulfide.
1 more element
A medium-voltage power cable, comprising:
- an insulative layer comprising:
- at least one elastomer comprising ethylene, propylene and ethylidene norbornene, wherein the ethylene content is of from 50 wt % to 80 wt %, based on total weight of the elastomer, and the ethylidene norbornene content is of from 1 wt % to 7 wt %, based on total weight of the elastomer;
- zinc oxide;
- and
- from 1 phr to 10 phr of one or more sulfides.
