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.

apply a strong enough force on an exterior of the tape separator configured to keep the tape separator and conductor core from slipping down an interior of the filler due to a gravitational force on the tape separator and 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.
16. The cable of claim 11 , wherein the armor is free of a jacket on an exterior of the armor.
17. The cable of claim 11 , wherein the tape separator is non-metallic.
18. The cable of claim 11 , wherein the conductor core comprises a ground wire adjacent at least one of the two or more conductors of the conductor core.
