Abstract

An electrical cable having a conductor having a protecting sheath and/or jacket comprising a base polymer (such as a thermoplastic or thermoset) having an abrasion reducing agent, a lubricant, a hydrophobic agent, and/or a UV protecting agent mixed therein. The resulting cable jacket and/or cable sheath defines an outer surface having abrasion reduction properties, lubricating properties, hydrophobic properties, and/or UV protecting properties.

Claims (45)

1. An electrical cable comprising:

at least one conductor capable of carrying an electrical current through the electrical cable; and

a sheath for protecting the conductor, wherein the sheath comprises:

a polymeric composition electrically insulating the conductor, wherein the polymeric composition comprises:

a Linear Low Density Polyethylene (LLDPE) base polymer; and

an abrasion reducing agent comprising molybdenum disulfide provided in an amount of between about 0.1% to about 5% by weight of the polymeric composition.

2. The electrical cable of claim 1 , wherein the polymeric composition comprises at least one of: a hydrophobic silica; an ultraviolet protecting agent; or a lubricant.

3. The electrical cable of claim 2 , wherein the polymeric composition comprises a lubricant, and wherein the lubricant comprises erucamide.

4. The electrical cable of claim 2 , wherein the polymeric composition comprises a lubricant, and wherein the lubricant comprises silicone oil.

5. The electrical cable of claim 1 , wherein the sheath comprises a first layer and a second layer, and wherein the first layer defines an outer surface of the electrical cable, and wherein the first layer comprises the polymeric composition.

6. The electrical cable of claim 5 , wherein the polymeric composition is a first polymeric composition, and wherein the second sheath layer comprises a second polymer composition different from the first polymer composition.

7. The electrical cable of claim 1 , wherein the polymeric composition comprises:

between about 0.1% to about 8% of an ultraviolet protecting agent;

between about 1% to about 15% of a lubricant; and

between about 1% to about 8% of a hydrophobic agent.

8. The electrical cable of claim 7 , wherein:

the ultraviolet protecting agent is selected from: zinc oxide, titanium dioxide, or carbon black;

the lubricant is selected from: silicone oil or erucamide; and

the hydrophobic agent is a hydrophobic silica.

9. An electrical cable comprising:

at least one conductor capable of carrying an electrical current through the electrical cable; and

a sheath for protecting the conductor, wherein the sheath comprises:

a polymeric composition electrically insulating the conductor, wherein the polymeric composition comprises:

a Linear Low Density Polyethylene (LLDPE) base polymer;

an abrasion reducing agent comprising molybdenum disulfide provided in an amount of between about 0.1% to about 5% by weight of the polymeric composition; and

a hydrophobic agent comprising a hydrophobic silica provided in an amount of between about 1% to about 8% by weight of the polymeric composition.

10. The electrical cable of claim 9 , wherein the hydrophobic silica is one of a fumed silica or a pyrogenic silica.

11. The electrical cable of claim 9 , wherein the polymeric composition comprises at least one of: an ultraviolet protecting agent or a lubricant.

12. The electrical cable of claim 11 , wherein the polymeric composition comprises a lubricant, and wherein the lubricant comprises silicone oil.

13. The electrical cable of claim 11 , wherein the polymeric composition comprises a lubricant, and wherein the lubricant comprises erucamide.

14. The electrical cable of claim 9 , wherein the sheath comprises a first layer and a second layer, and wherein the first layer defines an outer surface of the electrical cable, and wherein the first layer comprises the polymeric composition.

15. The electrical cable of claim 14 , wherein the polymeric composition is a first polymeric composition, and wherein the second sheath layer comprises a second polymer composition different from the first polymer composition.

16. An electrical cable comprising:

at least one conductor capable of carrying an electrical current through the electrical cable; and

a sheath for protecting the conductor, wherein the sheath comprises:

a polymeric composition electrically insulating the conductor, wherein the polymeric composition comprises:

a Linear Low Density Polyethylene (LLDPE) base polymer;

an abrasion reducing agent comprising molybdenum disulfide provided in an amount of between about 0.1% to about 5% by weight of the polymeric composition; and

a lubricant.

17. The electrical cable of claim 16 , wherein the lubricant is provided in an amount of between about 1% to about 15% by weight of the polymeric composition.

18. The electrical cable of claim 16 , wherein the polymeric composition comprises at least one of: a hydrophobic agent or an ultraviolet protecting agent.

19. The electrical cable of claim 16 , wherein the lubricant comprises silicone oil.

20. The electrical cable of claim 16 , wherein the lubricant comprises erucamide.

21. The electrical cable of claim 16 , wherein the sheath comprises a first layer and a second layer, and wherein the first layer defines an outer surface of the electrical cable, and wherein the first layer comprises the polymeric composition.

22. The electrical cable of claim 21 , wherein the polymeric composition is a first polymeric composition, and wherein the second sheath layer comprises a second polymer composition different from the first polymer composition.
