Armored cable with integral support
View Patent ↗A system for providing cable support may be provided. The system may comprise a conductor core, a filler that may provide integral core support, and armor. The conductor core may comprise at least one conductor. The filler may be applied around at least a portion of the conductor core. The armor may be applied around at least a portion of the filler. The applied armor may be configured to cause the filler to apply a strong enough force on an exterior of the conductor core configured to keep the conductor core from slipping down an interior of the filler due to a gravitational force. In addition, the applied armor may be configured to cause the filler to apply a strong enough force on an interior of the armor configured to keep a combination of the conductor core and the filler from slipping down the interior of the armor due to the gravitational force.
1. A cable comprising:
a conductor core comprising at least three conductors and at least one ground wire,
wherein the at least one ground wire is adjacent at least one of the at least three conductors;
a filler around the conductor core,
the filler comprising micro-spheres and a polyvinyl chloride; and
an electrically conductive armor around the filler,
the armor comprising a concave side facing the filler, wherein portions of the filler fill concavities created by the concave side.
2. The cable of claim 1 , wherein at least one of the at least three conductors is an insulated conductor.
3. The cable of claim 1 , wherein the at least three conductors are insulated conductors.
4. The cable of claim 3 , wherein the amount of micro-spheres is between 0.1% and 5% based on the total weight of the filler.
5. The cable of claim 1 , wherein the armor is free of a jacket on an exterior of the armor.
6. The cable of claim 1 , wherein the armor comprises a continuous strip applied helically around the filler.
7. The cable of claim 1 , wherein the armor comprises interlocked strips applied around the filler.
8. The cable of claim 1 , wherein the armor is configured to cause the filler to:
apply a strong enough force on an exterior of the conductor core configured to keep the conductor core from slipping down an interior of the filler due to a gravitational force on the conductor core when the cable is in a substantial vertical altitude; and
apply a strong enough force on an interior of the armor configured to keep a combination of the conductor core and the filler from slipping down the interior of the armor due to the gravitational force on the conductor core and a gravitational force on the filler.
9. A cable comprising:
a conductor core comprising two or more conductors and at least one ground wire,
wherein the at least one ground wire is adjacent at least one of the two or more conductors;
a filler around the conductor core,
the filler comprising micro-spheres and a polyethylene, a polyvinyl chloride, or a nylon; and
an electrically conductive armor around the filler,
the armor comprising a concave side facing the filler, wherein portions of the filler fill concavities created by the concave side.
10. The cable of claim 9 , wherein the filler comprises micro-spheres and polyethylene.
11. The cable of claim 9 , wherein the filler comprises micro-spheres and polyvinyl chloride.
12. The cable of claim 9 , wherein the amount of micro-spheres is between 0.1% and 5% based on the total weight of the filler.
13. The cable of claim 9 , wherein the armor is configured to cause the filler to:
apply a strong enough force on an exterior of the conductor core configured to keep the conductor core from slipping down an interior of the filler due to a gravitational force on the conductor core when the cable is in a substantial vertical altitude; and
apply a strong enough force on an interior of the armor configured to keep a combination of the conductor core and the filler from slipping down the interior of the armor due to the gravitational force on the conductor core and a gravitational force on the filler.
14. The cable of claim 9 , wherein the armor is free of a jacket on an exterior of the armor.
15. The cable of claim 9 , wherein the armor comprises a continuous strip applied helically around the filler.
16. The cable of claim 9 , wherein at least one of the conductors is an insulated conductor.
17. A cable comprising:
a conductor core comprising two or more conductors and at least one ground wire,
wherein the at least one ground wire is adjacent at least one of the two or more conductors;
a filler around at least a portion of the conductor core,
the filler comprising a foamed polyethylene, a foamed polyvinyl chloride, or a foamed nylon; and
an electrically conductive armor around the filler,
the armor comprising a concave side facing the filler, wherein portions of the filler fill concavities created by the concave side.
18. The cable of claim 17 , wherein the filler comprises foamed polyvinyl chloride.
19. The cable of claim 17 , wherein the armor is free of a jacket on an exterior of the armor.
20. The cable of claim 17 , wherein at least one of the conductors is an insulated conductor.
