Abstract
Embodiments of a fluid storage and introduction device 20 constructed in accordance with aspects of the present invention are provided. One embodiment of the device 20 includes an inner assembly 24 and an outer housing 26. When assembled, the device 20 is securely coupled to a cable or cable section 30 along a portion of its span. In use, the device 20 is capable of storing remediation fluid and introducing such fluid into the cable or cable section 30.
Claims17
An apparatus comprising:
- a span of cable having a conductive core and an insulation overlayer, wherein the span of cable includes an intermediate segment having an exposed core;
- a conductive housing that surrounds the intermediate segment of the cable having the exposed conductive core, wherein the housing is connected in electrical communication with the exposed conductive core and with a conductive layer of an outer assembly that surrounds the housing;
- and
- a pressure source disposed within the housing for applying a pressure to a remediation fluid disposed within the housing to force the remediation fluid into the power cable at the location of the exposed core.

A method for remediating an underground power cable or cable section, comprising:
- providing a power cable or cable section having a conductive core and an insulation overlayer, wherein the cable or cable section includes an intermediate segment having an exposed conductive core;
- positioning a fluid tight conductive housing in surrounding relation with the intermediate segment having the exposed core, wherein the housing includes a fluid reservoir disposed in fluid communication with the exposed core;
- positioning an outer assembly in surrounding relation with the housing, wherein the outer assembly includes a conductive inner layer, a conductive outer layer, and an insulating layer disposed between the inner layer and outer layer;
- connecting the exposed core in electrical communication with the conductive housing and the inner layer of the outer assembly;
- filling the fluid reservoir with a quantity of remediation fluid;
- applying a pressure on the remediation fluid disposed within the fluid reservoir;
- supplying, over a period of time, remediation fluid from the fluid reservoir to a region of the cable or cable section located exteriorly of the housing.
