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 gas blocking cable comprising:
- a plurality of wires, each wire including
- i. a plurality of conductors having interstitial areas there between;
- ii. an insulation material circumferentially surrounding the plurality of conductors;
- iii. a conductor filling material positioned within the interstitial areas between the plurality of conductors;
- b) a shield circumferentially surrounding the plurality of wires so that a cable is formed with areas between the plurality of wires;
- a wire filling material positioned within the areas between the plurality of wires;
- and
- d) wherein 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.
A method for making a gas blocking cable comprising the steps of:
- a) cabling a plurality of conductors so that interstitial areas are formed there between;
- b) applying a conductor filling material to the interstitial areas between the plurality of conductors so that the 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 areas are formed there between;
- f) applying a wire filling material to the areas between the plurality of wires so that the areas are filled, where the wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200° C.;
- and
- g) applying a shield material so as to circumferentially surround the first and second wires and the wire filling material.
