Abstract
A gas blocking cable includes cabled wires, where each wire includes cabled conductors having interstitial areas there between. An insulation material circumferentially surrounds the cabled conductors and a conductor filling material is positioned within the interstitial areas between conductors. A shield circumferentially surrounds the cabled wires so that a cable is formed with areas between the wires. A wire filling material is positioned within the areas between the wires. Each of the conductor filling material and wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.
Claims20
A method for making a gas blocking cable comprising the steps of:
- a) cabling a plurality of conductors so that a first set of interstitial areas are formed there between;
- b) applying a conductor filling material to the first set of interstitial areas between the plurality of conductors so that the first set of interstitial areas are filled, where the conductor filing material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- c) applying insulation so as to circumferentially surround the plurality of conductors and conductor filling material so that a first wire is formed;
- d) repeating steps a) through c) so that a second wire is formed;
- e) cabling the first and second wires so that a second set of interstitial areas are formed there between;
- f) applying a wire filling material to the second set of interstitial areas between the first and second wires so that the second set of interstitial areas are filled, where the wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- g) applying a shield material so as to circumferentially surround the first and second wires and the filling material;
- h) applying a jacket material over the applied shield material, wherein the jacket material is extruded and circumferentially surrounds the shield material with a jacket filling material positioned within a third set of interstitial areas between the shield material and the jacket material, where the jacket filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- and
- i) braiding a fiberglass material over the applied jacket material,
- wherein the gas blocking cable blocks a passage of a high pressure gas or a high pressure fluid through the first set of interstitial areas, the second set of interstitial areas, and the third set of interstitial areas to prevent the passage of the high pressure gas or the high pressure fluid.
A method for making a gas blocking cable comprising the steps of:
- a) cabling a plurality of conductors with a first space formed there between;
- b) applying a conductor filling material to the first space between the plurality of conductors so that the first space is filled, where the conductor filing material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- c) applying insulation so as to circumferentially surround the plurality of conductors and conductor filling material so that a first wire is formed;
- d) repeating steps a) through c) so that a second wire is formed;
- e) cabling the first and second wires with a second space is formed there between;
- f) applying a wire filling material to the second space between the first and second wires so that the second space is are filled, where the wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- g) applying a shield so as to circumferentially surround the first and second wires and the filling material;
- and
- h) braiding a fiberglass material over the applied shield,
- wherein the gas blocking cable blocks a passage of a high pressure gas or a high pressure fluid through the first space and the second space to prevent the passage of the high pressure gas or the high pressure fluid.
