Abstract

A cable that include a hose having a conductor located thereabout. A first strength member layer is located about the conductor. A second strength member layer is located about the first strength member layer. A first jacket is located about the second strength member layer. The first jacket is fiber-reinforced. A second jacket is located about the first jacket. The second jacket is a contrasting color to the first jacket.

First claim

We claim:

1. A cable comprising:
a hose configured to allow pressurized air to pass therethrough, wherein the hose comprises three layers comprising: an inner hose layer that is a first material, wherein the first material comprises at least one of linear low density polyethylene, Low-density polyethylene high-density polyethylene, polypropylene, or ethylene-propylene copolymer, a reinforcement layer that includes a spring disposed about the inner hose layer and encapsulated by a second material that is different from the first material, wherein the second material is nylon, and wherein a tie layer bonds with the first material and second material is located between the inner hose layer and reinforcement layer, and an outer hose layer, wherein the inner hose layer is bonded with the second material, and wherein the outer hose layer is bonded with the second material;
at least one conductor located about the hose;
a first strength member layer located about the at least one conductor;
a second strength member layer located about the first strength member layer;
a first jacket located about the second strength member layer, wherein the first jacket is fiber-reinforced; and
a second jacket located about the first jacket, wherein the second jacket is a contrasting color to the first jacket.

2. The cable of claim 1 , wherein the first jacket is made from a polymer.

3. The cable of claim 1 , wherein the second jacket is made from a polymer.

4. The cable of claim 1 , wherein the first strength member layer comprises a plurality of coated strength members.

5. The cable of claim 1 , wherein the second strength member layer comprises another plurality of coated strength members.

6. The cable of claim 1 , wherein a tie layer is located between the first jacket and the second jacket.

7. The cable of claim 6 , wherein the first jacket is made from nylon and the second jacket is made from a fluoropolymer.

8. The cable of claim 1 , wherein the first jacket is made from a polymer.

9. The cable of claim 1 , wherein the second jacket is made from a polymer.

10. The cable of claim 1 , wherein the first strength member layer comprises a plurality of coated strength members.

11. A cable comprising:
a hose configured to allow pressurized air to pass therethrough, wherein the hose comprises three layers comprising: an inner hose layer that is a first material, wherein the first material comprises at least one of linear low density polyethylene, Low-density polyethylene high-density polyethylene, polypropylene, or ethylene-propylene copolymer, a reinforcement layer that includes a composite tape wrapped about the inner hose layer, wherein gaps are formed between portions of the composite tape, and wherein a second material encapsulates the composite tape and bonds with the first material, wherein the second material is not the same as the first material, wherein the second material is nylon, and wherein a tie layer bonds with the first material and second material, and an outer hose layer, wherein the outer hose layer is bonded with the reinforcement layer;
at least one conductor located about the hose;
a first strength member layer located about the at least one conductor;
a second strength member layer located about the first strength member layer;
a first jacket located about the second strength member layer, wherein the first jacket is fiber-reinforced; and
a second jacket located about the first jacket, wherein the second jacket is a contrasting color to the first jacket.
