the at least one conductor spacer comprises,

a central portion defining a central opening configured to engage and retain the center conductor, and

a plurality of arm members extending radially from the central portion and defining a plurality of outer openings configured to engage and retain the plurality of outer conductors.

5. The cable of claim 1 , wherein the at least one conductor spacer comprises a plurality of conductor spacers connected to each other to form a foldable linkage of conductor spacers, each conductor spacer among the plurality of conductor spacers comprising a body member including a central opening configured to receive and engage a respective conductor among the plurality of conductors.

6. The cable of claim 5 , wherein adjacent conductor spacers among the plurality of conductor spacers are connected at pivoting joints formed by interlocking pivot members.

7. The cable of claim 5 , wherein adjacent conductor spacers among the plurality of conductor spacers are connected at flexible joints formed by interlocking flexible members.

8. The cable of claim 1 , wherein the sealing material is a urethane material.

9. The cable of claim 1 , wherein the sealing material is disposed between the conductor spacer and an end of the outer jacket, and between the conductor spacer and an outer end of the break-out boot.

10. A method of assembling a multi-conductor cable, comprising:

providing a multi-conductor cable comprising,

a main body portion,

a break-out portion adjacent to the main body portion,

an outer jacket in the main body portion, and

a plurality of conductors extending within the outer jacket in the main body portion and extending outside of the outer jacket in the break-out portion;

arranging at least one conductor spacer within the break-out portion to engage the plurality of conductors and retain the plurality of conductors in a spaced relationship with one another;

attaching a break-out boot to the outer jacket and arranging the break-out boot around the plurality of conductors in the break-out portion; and

placing sealing material in the break-out boot in spaces between the plurality of conductors.

11. The method of claim 10 , wherein:

the at least one conductor spacer comprises a plurality of openings configured to engage and retain the plurality of conductors; and

arranging at least one conductor spacer within the break-out portion to engage the plurality of conductors and retain the plurality of conductors in the spaced relationship with one another comprises arranging the at least one conductor spacer within the break-out portion to cause the plurality of openings to engage and retain the plurality of conductors.

12. The method of claim 10 , comprising providing a plurality of openings in the at least one conductor spacer that are configured to enable the sealing material to flow through the at least one conductor spacer.

13. The method of claim 10 , wherein:

the plurality of conductors comprises a center conductor disposed substantially along a central axis of the outer jacket and a plurality of outer conductors disposed around the center conductor;

the at least one conductor spacer comprises,

a central portion defining a central opening, and

a plurality of arm members extending radially from the central portion and defining a plurality of outer openings; and

arranging at least one conductor spacer within the break-out portion to engage the plurality of conductors and retain the plurality of conductors in the spaced relationship with one another comprises arranging the at least one conductor spacer to cause the central opening to engage and retain the center conductor, and to cause the plurality of outer openings to engage and retain the plurality of outer conductors.

14. The method of claim 13 , wherein connecting the conductor spacers among the plurality of conductor spacers to each other comprises connecting adjacent conductor spacers among the plurality of conductor spacers at pivoting joints formed by interlocking pivot members.

15. The method of claim 13 , wherein connecting the conductor spacers among the plurality of conductor spacers to each other comprises connecting adjacent conductor spacers among the plurality of conductor spacers at flexible joints formed by interlocking flexible members.

16. The method of claim 10 , wherein:

the at least one conductor spacer comprises a plurality of conductor spacers, each conductor spacer among the plurality of conductor spacers comprising a body member including a central opening; and

arranging at least one conductor spacer within the break-out portion to engage the plurality of conductors and retain the plurality of conductors in the spaced relationship with one another comprises,

connecting the conductor spacers among the plurality of conductor spacers to each other to form a foldable linkage of conductor spacers, and

inserting each conductor among the plurality of conductors in the central opening of a respective conductor spacer among the plurality of conductor spacers.

17. The method of claim 10 , wherein the sealing material is a urethane material.

18. The method of claim 10 , wherein placing the sealing material in the break-out boot in spaces between the plurality of conductors comprises placing the sealing material between the conductor spacer and an end of the outer jacket, and between the conductor spacer and an outer end of the break-out boot.
