摘要： A splice joins two pushing and pulling cables. Each cable has a plurality of gripping members defining a longitudinal cavity, a bendable power line housed in the cavity and elongated tensile elements enclosed and compressed by the gripping members. The adjacent ends of the tensile elements are connected by tensile element splices. Adjacent ends of the power lines are connected by a power line splice. A plurality of splice blocks are located end to end along the longitudinal axis, and enclose and compress the tensile element splices and the tensile element. The splice blocks define a longitudinally extending chamber housing the power line and the power line splice in a relatively stress free state.

摘要： An armored electrical cable which is especially useful in oil wells and provides resistance to corrosion, explosive decompression and transverse compressive forces. The cable comprises an insulated conductor, a barrier layer enclosing the insulation, a filler layer enclosing the barrier layer, and a square compression-resistant layer enclosing the filler layer. The barrier layer is a lead sheath having a closed cross section with an exterior including four right angle corners oriented in a square and four convex areas, each interconnecting a pair of adjacent right angle corners. The filler layer comprises a thermosetting tape, an open-mesh fabric tape, and a polymeric tape of low frictional coefficient.

摘要： An elongated, reinforced power cable for use in adverse environments. The cable is provided with internal structural members to resist crushing and other mechanical forces. The cable includes at least two power conductor assemblies which extend along the longitudinal axis of the cable. A protective metallic layer is provided for each conductor assembly and completely encases each conductor assembly. The conductor assemblies and protective metallic layers are aligned in a row within the cable, the row having a left end, a right end, a top plane and a bottom plane. A rigid support member is positioned at each end of the row of conductor assemblies. The support members have a height at least equal to the height of the protective layers to prevent compression of the protective layers and conductor assemblies. An armored covering is provided which fully encloses the support members, the protective layers and the conductor assemblies. The row has portions of the top and bottom planes which are not covered by a rigid support member. The protective metallic layers may have either a square cross section or a generally square cross section with chamfered edges.

摘要： A power line for an electrical submersible pump has three metallic impermeable tubes. A single electrical conductor is located within each of the tubes. Each conductor has at least one elastomeric insulation layer surrounding it. An annular portion of the insulation layer of each of the electrical conductors is in tight contact with the tube to form a seal. The annular portions may be annular crimps formed in the tube at intervals. The annular portion could also be a continuous seal caused by swelling of the insulation layer due to contact with a hydrocarbon.

摘要： An electrical line for installation in a well for transmitting power to a well pump includes a string of coiled tubing. An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Retainers are mounted to the electrical cable and spaced longitudinally apart from each other. An indentation is integrally formed in the tubing adjacent each of the retainers. Each indentation protrudes into the interior passage of the tubing and creates a ledge which is contacted by one of the retainers when the electrical line is installed in the well. The indentations and retainers transfer weight of the electrical cable to the tubing. Weld material is filled into the depression on the surface created by each indentation.

摘要： An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of insulated conductors have a protective jacket extruded thereabout, the protective jacket having an exterior ribbed surface which includes a plurality of longitudinally extending ribs between which extend a plurality of thermal expansion voids. The protective jacket is formed from a thermally set elastomeric material which is partially cured, and then a protective exterior armor is helically wrapped around the exteriorly ribbed surface of the elastomeric, protective jacket. Then, the electric cable is heated to an elevated temperature for a period of time which is sufficient for fully curing the elastomeric protective jacket formed therein.

摘要： An electrical cable connector for connecting an electrical cable to an electric motor, especially in an oil well. The electrical cable connector includes a hollow cylindrical housing receiving a portion of the electrical cable therein and a sealing assembly for sealing the space between the cable and the housing to prevent the corrosive material in the oil well from eroding the electrical connection. The sealing assembly includes a disk rigidly coupled to the housing and a movable disk axially biased towards the other disk. A sealing plug is positioned between the two disks and comprises a substantially uncured flowable, incompressible seal material sandwiched between a pair of cured rubber sealing disks. The movable disk asserts pressure on the sealing plug so that the flowable material will flow into any otherwise empty spaces between the sealing disks and the cable and between the sealing disks and the housing.
