A method of building an insulation system around an axial section of a conductor of a power cable, the method including: a) providing a power cable including a conductor and an insulation system arranged around the conductor, the insulation system including insulation system layers, including an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer, wherein the power cable includes an axial section between a first insulation system section and a second insulation system section of the insulation system which at least is without an outer semiconducting layer, b) winding a tape around the conductor along the axial section in a plurality of layers to form a plurality of layers of tape connecting with the first insulation system section and the second insulation system section, and c) heating the plurality of layers of tape to melt and fuse the plurality of layers of tape to form an insulation system layer between the first insulation system section and the second insulation system section, wherein the tape has a width defined by a distance between lateral edges, wherein the tape has a mid-section between its lateral edges, wherein in the mid-section the tape has a largest thickness, and wherein the thickness of the tape decreases from the mid-section towards both lateral edges.

The present disclosure provides a self-traction wire coating robot and a wire routing and wire hanging method, wherein the robot includes a mounting plate, a material pushing module, a winding traction module, a coating module, a walking module and a power supply and control module, wherein the coating module and the walking module are rotatable in the extension direction of the non-overhead bare wires, when hanging wires, the coating module and the walking module are first rotated and swung to the side of the robot, an unmanned device is then used to hang a traction belt on the overhead bare wires, the winding traction module tightens the traction belt to hang the robot under the overhead bare wires, and then the coating module and the walking module are controlled to rotate and recover to the top of the robot and hang the robot on the overhead bare wire.

Assemblies and methods of use are disclosed for repairing the coating of a coated wellbore line. A wellbore line can be cleaned and then coated with a repair material before being pulled through a die to shape the coating and then being pulled through setting section to set the repair material. The repair material can be a thermoplastic material that is set by cooling, or a thermoset material that is set by heating. The wellbore line can be repaired upon exiting a wellbore or being unspooled from a reel.

A valve assembly that includes a valve body, a poppet member, and a biasing member. The valve body has an internal through-channel. The poppet member has an inside portion positioned at least partially inside the through-channel and an outside portion positioned outside the through-channel and extending outwardly beyond the valve body. The poppet member is movable within the through-channel between an open position and a closed position. The biasing member is external to the valve housing and applies a biasing force to the outside portion of the poppet member that biases the poppet member toward the closed position.

A stripping tool for cutting the armor sheathing of a cable. The stripping tool includes a cable receiving handle defining a cable receiving channel and a saw handle movably mounted to the cable receiving handle. A saw assembly, including at least one saw blade, is supported by the saw handle and moveable relative to the cable receiving handle. The saw assembly configured to cut two successive wraps of the armor sheathing of the cable.

Generating an assessment of the suitability of cables, ducts, tubes, pipes and/or other hollow-type of conduits to extraction of cores, conductors, insulation, etc. included therein while still buried in the ground or otherwise positioned out-of-sight so as to be unavailable for visual and/or physical inspection is contemplated. The assessment may be used to indicate a suitability of a cable buried in the ground of a hybrid fiber coaxial (HFC) cable plant to extraction of the type whereby a core of the cable may be extracted using hydraulics while still buried.
