Abstract

An electric conductor may be provided. The electric conductor may comprise a conductor core and a plurality of conductor strands wrapped around the conductor core. The conductor core may comprise a plurality of core strands comprising an overall number of strands. The plurality of core strands may comprise a first portion of core strands and a second portion of core strands. The first portion of core strands may comprise a first number of strands. The first portion of core strands may comprise steel. The second portion of core strands may comprise a second number of strands. The second portion of core strands may comprise a composite material. A ratio of the first number of strands to the overall number of strands and a ratio of the second number of strands to the overall number of strands may be optimized to give the conductor core a predetermined characteristic.

Claims (22)

1. An apparatus comprising:

a conductor core comprising,

a core center strand comprising a composite material wherein the composite material comprises fibers disposed in a thermoplastic matrix, and

core layer strands wrapped around the core center strand and being in contact with the core center strand wherein the core layer strands comprise a first portion of core strands comprising a first material and a second portion of core strands comprising the composite material; and

a plurality of conductor strands wrapped around the conductor core and being in contact with the core layer strands.

2. The apparatus of claim 1 , wherein the fibers comprise carbon fibers.

3. The apparatus of claim 1 , wherein the thermoplastic matrix comprises a polyphenylene sulfide.

4. The apparatus of claim 1 , wherein the composite material has an elastic modulus in a range from about 70 GPa to about 300 GPa.

5. The apparatus of claim 1 , wherein the composite material has at least one of the following: a density in a range from about 1.2 g/cc to about 1.8 g/cc; a strength to weight ratio in a range from about 500 MPa/(g/cc) to about 1,100 MPa/(g/cc); a percent elongation at break in a range from about 1% to about 2.5%; a linear thermal expansion coefficient in the longitudinal direction in a range from about −0.4 to about 5 ppm per ° C.; a bending radius in a range from about 1 cm to about 50 cm; and a void fraction of less than about 6%.

6. The apparatus of claim 1 , wherein the first material comprises one of the following: steel, standard strength steel, high strength steel, extra high strength steel, and ultra-high strength steel, aluminum zirconium, and 1350-“O” temper aluminum.

7. An apparatus comprising:

a conductor core comprising a plurality of core strands comprising an overall number of strands, the plurality of core strands comprising:

a first portion of core strands comprising a first number of strands, the first portion of core strands comprising a first material, and

a second portion of core strands comprising a second number of strands, the second portion of core strands comprising a composite material wherein a ratio of the first number of strands to the overall number of strands and a ratio of the second number of strands to the overall number of strands are optimized to give the conductor core a predetermined characteristic, the first material having a higher elasticity modulus than the composite material, the first material having a higher thermal elongation than the composite material, and the first material having a higher conductivity than the composite material.

8. The apparatus of claim 7 , wherein the predetermined characteristic comprises elasticity modulus.

9. The apparatus of claim 7 , wherein the predetermined characteristic comprises thermal elongation.

10. The apparatus of claim 7 , wherein the predetermined characteristic comprises conductivity.

11. The apparatus of claim 7 , wherein the ratio of the first number of strands to the overall number of strands is 1:7.

12. The apparatus of claim 7 , wherein the ratio of the first number of strands to the overall number of strands is 2:7.

13. The apparatus of claim 7 , wherein the composite material comprises fibers disposed in a thermoplastic matrix.

14. The apparatus of claim 7 , wherein the first material comprises one of the following: standard strength steel, high strength steel, extra high strength steel, ultra-high strength steel, aluminum zirconium, and 1350-“O” temper aluminum.

15. The apparatus of claim 7 , further comprising a plurality of conductor strands wrapped around the conductor core.
