Abstract
An insulation composition for a high-voltage cable according to an example of the present disclosure includes a base resin, a flame retardant, a cross-linking agent, and other additives. Here, the base resin includes 30 to 60 wt % of a polar ethylene-based copolymer, 20 to 50 wt % of ethylene-propylene rubber or ethylene alpha-olefin, and 10 to 20 wt % of maleic anhydride-modified ethylene-vinyl acetate.
Claims20
An insulation composition for an electrical cable, the insulation composition comprising:
- a base resin;
- a flame retardant;
- a cross-linking agent;
- and
- at least one other additive, wherein the base resin comprises:
- 30 to 60 wt % of a polar ethylene-based copolymer, 20 to 50 wt % of ethylene-propylene rubber or ethylene alpha-olefin, and 10to 20 wt % of ethylene-vinyl acetate modified with maleic anhydride.
An electrical cable comprising:
- an electrical conductor wire;
- and
- a sheath that surrounds the electrical conductor wire,
- wherein the sheath is made from an insulation composition comprising:
- a base resin,
- a flame retardant, and
- a cross-linking agent,
- wherein the base resin comprises 30 to 60 wt % of a polar ethylene-based copolymer, 20 to 50 wt % of ethylene-propylene rubber or ethylene alpha-olefin, and 10 to 20 wt % of ethylene-vinyl acetate modified with maleic anhydride.
A vehicle comprising:
- a battery;
- and
- an electrical cable electrically connected to the battery,
- wherein the electrical cable comprises an electrical conductor wire and a sheath that surrounds the electrical conductor wire,
- wherein the sheath is made from an insulation composition comprising:
- a base resin,
- a flame retardant, and
- a cross-linking agent,
- wherein the base resin comprises 30 to 60 wt % of a polar ethylene-based copolymer, 20 to 50 wt % of ethylene-propylene rubber or ethylene alpha-olefin, and 10 to 20 wt % of ethylene-vinyl acetate modified with maleic anhydride.
