An adapter ferrule is provided configured to connect between a connector and an armored cable. The connector has a connection piece, a nut thread, a lock nut, and a ferrule, the ferrule having at least a threaded region of a first thread standard. The armored cable has a second thread standard different from the first thread standard. The adapter ferrule has a small block and a large block. The small block has an internal threading matching the second thread standard of the armor, the outer dimension of which fits within the threaded region of the ferrule. The large block has a recessed thread configured to fit over the outside of the threaded region of the ferrule, the recessed thread having the same thread standard as the threaded region of the ferrule.

A reinforced power cable system for use with an electric artificial lift system is provided. The system includes an electric artificial lift system. The system also includes a power cable that provides power to the electric artificial lift system from a surface of a well. The power cable includes at least one conductor positioned within a cable jacket and a braided tube with an open-weave of a reinforcing component installed around the cable jacket. Additionally, the power cable includes a coil tube welded around the braided tube.

The present disclosure discloses a hoisting cable with small diameter, high strength, and high flexibility, including an inner conductive core, an insulating layer, an outer conductive wire layer, a tensile layer, and an outer protective layer. The insulating layer is located at an outer side of the inner conductive core and provides insulation between the inner and outer conductors; the outer conductive wire layer is located at an outer side of the insulating layer; the tensile layer is located at an outer side of the outer conductive wire layer; and the outer protective layer is located at an outer side of the tensile layer. The high tensile strength can ensure the safety of hoisting operations, and the small diameter, small bend radius, and high flexibility can ensure the minimization design and the large rope capacity of a winch.

A fire resistant coaxial cable and method of making is described that has a 2-part dielectric made of a polymer foam and a ceramifiable silicone rubber. The polymer foam, which can be polypropylene or other polymers, leaves little-to-no residue in the cable that causes electromagnetic loss when upon burning. The polymer foam can be extruded over a center conductor using an inert gas, such as nitrogen, to propagate the foam, ensuring little-to-no residue in the cable. The ceramifiable silicone rubber can be extruded over the polymer foam. The ceramifiable silicone rubber can have a polysiloxane matrix with inorganic flux and refractory particles that ceramify under high heat, such as temperatures specified by common fire test standards (e.g., 1850° F./1010° C. for two hours). The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor even under aforementioned fire tests. Another layer of ceramifiable silicone rubber surrounds the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.

A reinforced superconducting wire (1a) has a superconducting core strand (2) and a first cladding with a multitude of reinforcing strands (3). The reinforcing strands (3) are arranged around the circumferential surface of the superconducting core strand (2) in a non-crossing manner and are in contact with the core strand (2). The wire has a reinforcement for enhancing its mechanical properties against external stresses and for preventing diameter expansion during heat treatment. In addition to other advantages, such superconducting wire can be produced with an easy and low-cost production process.

The subject matter of the invention is an adhesive tape, in particular a wrapping tape for sheathing cables in automobiles. The tape has a fabric backing (1, 3, 2, 4) in the form of a monoweave and an adhesive coating (7) on at least one side of the backing (1, 3, 2, 4). According to the invention, the monoweave is at least three-ply, and abrasion-resistant, non-connected warp threads (1, 3) form an outer layer and an inner layer. An intermediate layer made of weft threads (2, 4) is provided, the bonding points (5) of said layer coinciding with those of the outer layer and not with the bonding points (6) of the inner layer.
