A cable assembly having a plurality of conductors arranged side-by-side within a first plane to form a substantially flat portion thereof is included, each conductor being connected to a corresponding feedthrough of the feedthrough assembly and the flat portion extending from the body.

Proposed is a method for producing an insulating composite material for a silicone rubber socket, in which the method includes a step of producing a molded body of a mixture of liquid silicone and a heterogeneous composite powder composited from (i) metal powder and (ii) polymer or ceramic powder. An insulating composite material for a silicone rubber socket, produced by the method, is also proposed. Further proposed is a silicone rubber socket manufacturing method including the steps of producing a sheet-shaped molded body from a mixture including liquid silicone and a heterogeneous composite powder composited from (i) a metal powder and (ii) a polymer or ceramic powder and (b) forming a plurality of pores extending through the sheet-shaped molded body in a thickness direction and filling the pores with a conductive material. In addition, a silicone rubber socket manufactured by the method is also proposed.

Disclosed are a stress-resistant, creep-resistant, high-temperature resistant and high-insulation sheath material for a maglev train cable, and a manufacturing method and use thereof. A multiple chemical crosslinking structure is constructed by blending a functional polyvinylsilicone grease with ultra-high molecular weight polyethylene (UHMWPE) and a ceramicized silicone rubber as a cable material matrix and using electron beam irradiation. In addition, organic/inorganic fillers in the matrix can form physical crosslinking points in the material. A physical-chemical dual crosslinking structure is constructed in the matrix, which can limit the motion and relaxation of molecular chains and improve the interaction between the insulation layer and sheath layer and refractory layers such as fillers and mica tapes to avoid the relative displacement during the laying and operation and improve the high-temperature resistance, creep resistance and stress relaxation resistance of a UHMWPE cable sheath material.

A silicone extension for an ignition coil for internal combustion engines including an elongated tubular body extending along its main direction between a first end portion, shaped to be engaged in a container containing electrical/electronic means for the generation of high voltage electrical energy, and a second end portion shaped to accommodate the insulating body of an ignition spark plug, wherein the tubular body is made of self-lubricating silicone rubber.

A percutaneous connector assembly including a feedthrough assembly having a body and a plurality of electrically conductive feedthroughs extending through the body from a first end toward a second end thereof. A cable assembly having a plurality of conductors arranged side-by-side within a first plane to form a substantially flat portion thereof is included, each conductor being connected to a corresponding feedthrough of the feedthrough assembly and the flat portion extending from the body.

A single-component conductive adhesive with low hardness, and method of manufacture and use are provided. The conductive adhesive may include a resin composition, an organic solvent and nickel-coated graphite powder. The weight ratio of the resin composition to nickel-coated graphite powder may be 20%:80% or 40%:60%. The weight of the organic solvent may be 20-40% the weight of the resin composition. The resin composition may include 20-40% by weight of vinyl-terminated polydimethylsiloxane (PDMS), 5-15% by weight of HSi polysiloxane oil, 0.05-0.15% by weight of polymerization inhibitor, and 0.1-1% by weight of encapsulated platinum complex.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
