Claims
- 1. A method of forming a cable for an electrical submersible pump, comprising:
- placing three insulated power conductors in a side by side flat configuration, defining an assembly of power conductors with two outside conductors and an intermediate conductor; then
- wrapping a metal strip around the assembly of power conductors to hold the power conductors in the side by side flat configuration and to provide an inner armor which has two flat sides joined by two curved sides; then
- placing at least one auxiliary line in a side by side position in contact with one of the curved sides of the inner armor; and
- wrapping a metal strip helically around the auxiliary line and over the inner armor, thereby forming a cable for an electrical submersible pump, with the metal strip wrapped around the auxiliary line holding the auxiliary line in the side by side position and defining an outer armor.
- 2. The method according to claim 1, wherein:
- the step of placing three insulated power conductors in a side by side flat configuration comprises providing each of the power conductors with the same outer diameter; and
- the step of placing at least one auxiliary line in a side by side position comprises providing the auxiliary line with an outer diameter that differs from the outer diameter of the power conductors.
- 3. The method according to claim 1, wherein:
- the step of placing three insulated power conductor in a side by side flat configuration comprises providing each of the power conductors with the same outer diameter; and
- the step of placing at least one auxiliary line in a side by side position comprises providing the auxiliary line with an outer diameter that is less than the outer diameter of the power conductors.
- 4. The method according to claim 1, wherein:
- the step of placing at least one auxiliary line in a side by side position comprises providing the auxiliary line with a hollow tubular interior for passing fluids.
- 5. The method according to claim 1, wherein:
- the step of placing at least one auxiliary line in a side by side position comprises providing the auxiliary line with an interior containing an electric wire for transmitting electricity.
- 6. The method according to claim 1, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing the strip of the outer armor with a width that is greater than the width of the strip of the inner armor.
- 7. The method according to claim 1, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing the strip of the outer armor with a thickness that is greater than the thickness of the strip of the inner armor.
- 8. The method according to claim 1, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing a different metal for the strip of the outer armor than the metal used for the strip of the inner armor.
- 9. The method according to claim 1 wherein the step of placing at least one auxiliary line in a side by side position comprises placing two of the auxiliary lines in a side by side position, one located on each side of the inner armor.
- 10. A method of forming a cable for an electrical submersible pump, comprising:
- placing three insulated power conductors adjacent each other to form an assembly of power conductors; then
- wrapping a metal strip helically around the assembly of power conductors to hold the power conductors adjacent each other and provide an inner armor; then
- placing at least one auxiliary line in contact with an exterior side of the inner armor; and
- wrapping a metal strip helically around the auxiliary line and over the inner armor to form a cable for an electrical submersible pump, with the metal strip wrapped around the auxiliary line securing the auxiliary line to the inner armor and defining an outer armor.
- 11. The method according to claim 10, wherein:
- the step of placing three insulated power conductor adjacent each other comprises providing each of the power conductors with the same outer diameter; and
- the step of placing at least one auxiliary line in contact with an exterior side comprises providing the auxiliary line with an outer diameter that differs from the outer diameter of the power conductors.
- 12. The method according to claim 10, wherein:
- the step of placing three insulated power conductor adjacent each other comprises providing each of the power conductors with the same outer diameter; and
- the step of placing at least one auxiliary line in contact with an exterior side comprises providing the auxiliary line with an outer diameter that is less than the outer diameter of the power conductors.
- 13. The method according to claim 10, wherein:
- the step of placing at least one auxiliary line in contact with an exterior side comprises providing the auxiliary line with a hollow tubular interior for passing fluids.
- 14. The method according to claim 10, wherein:
- the step of placing at least one auxiliary line in contact with an exterior side comprises providing the auxiliary line with an interior containing an electric wire for transmitting electricity.
- 15. The method according to claim 10, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing the strip of the outer armor with a width that is greater than the width of the strip of the inner armor.
- 16. The method according to claim 10, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing the strip of the outer armor with a thickness that is greater than the thickness of the strip of the inner armor.
- 17. The method according to claim 10, wherein:
- the step of wrapping a metal strip helically around the auxiliary line comprises providing a different metal for the strip of the outer armor than the metal for the strip of the inner armor.
- 18. A method of forming a cable for an electrical submersible pump, comprising:
- assembling three insulated power conductors of the same outer diameter adjacent and in contact with each other to form an assembly of power conductors; then
- wrapping a metal strip helically around the assembly of power conductors to hold the power conductors in contact with each other and provide an inner armor; then
- placing at least one auxiliary line in contact with an exterior side of the inner armor; and
- wrapping a metal strip helically around the auxiliary line and over the inner armor to secure the auxiliary line to the inner armor to define an outer armor and to provide a cable for an electrical submersible pump.
