Abstract

A cable that has a cable core with a first armor wire layer and a second armor wire layer. The second armor wire layer is segregated from the first armor wire layer, and an outer jacket is disposed about the second armor wire layer.

First claim

What is claimed is:

1. A cable comprising:
a cable core;
a first armor wire layer, wherein the first armor wire layer is at least partially embedded in a first insulating layer disposed about the cable core; and
a second armor wire layer, wherein the second armor wire layer is segregated from the first armor wire layer, wherein the second armor wire layer is separated from the first armor wire layer by a second insulating layer, wherein the second insulting layer comprises a low-melt-temperature polymer disposed about a high-melt-temperature polymer, a plurality of ridges, a carbon reinforced polymer, a bondable tape, a cross-linked polymer bonded with another polymer, a cabled yarn, or combinations thereof.

2. The cable of claim 1 , further comprising:
a first insulating layer disposed between the cable core and the first armor wire layer.

3. The cable of claim 2 , further comprising:
an outer jacket disposed about the second insulating layer.

4. The cable of claim 1 , wherein the first insulating layer is bonded with the second insulating layer.

5. A cable comprising:
a cable core;
a first armor wire layer, wherein the first armor wire layer is embedded in a first insulating layer disposed about the cable core;
a second armor wire layer, wherein the second armor wire layer is segregated from the first armor wire layer by a second insulating layer, wherein the second insulting layer comprises a low-melt-temperature polymer disposed about a high-melt-temperature polymer, a plurality of ridges, a carbon reinforced polymer, a bondable tape, a cross-linked polymer bonded with another polymer, a cabled yarn, or combinations thereof; and
an outer jacket disposed about the second armor wire layer.

6. The cable of claim 5 , further comprising:
the first insulating layer disposed between the cable core and the first armor wire layer.

7. The cable of claim 5 , further comprising:
the second insulating layer disposed between the first armor wire layer and the second armor wire layer, wherein the first insulting layer is bonded with the second insulating layer.
