A component of an exhaust system for an internal combustion engine. The component comprises an exhaust system structure (20) having an interior (22) through which exhaust gases flow and an exterior (21), and a thermal insulating wrap (10) for thermally insulating at least a portion of the exterior (21) of the exhaust system structure (20). The thermal insulating wrap (10) comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder wrap (11). The pliable binder wrap (11) is wound completely around at least a portion of the exhaust system structure (20). It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder wrap (11) and the exterior 21 of the exhaust system structure (20).

An ultra high temperature mineral-insulated shielded cabled is provided as a non-sintered compacted powder, where central conductors and/or a sheath are made of a conducting material selected from tantalum, tungsten, rhodium, rhenium, carbon, and a mixture of at least two of such materials. The mineral insulator is made of an insulating material selected from boron nitride, yttrium oxide, silicon nitride, aluminium nitride, and a mixture of such materials. The conductor is tantalum and the insulator is selected from hafnia, boron nitride, silicon nitride, and a mixture of such materials, in particular for a use at a temperature lower than 1 630? C. or 1 600? C.; or aluminium nitride, in particular at a temperature lower than 1 530? C. or 1 500? C. A device including this cable used below 1800? C., particularly under 1 600? C., in particular under vacuum, as a heating element or transmission cable.

A method can include extruding polyethylene about a lead (Pb) barrier layer disposed about a conductor to form an assembly; and armoring at least one of the assemblies with metallic armor to form a cable. A power cable can include a conductor; a lead (Pb) barrier layer disposed about the conductor; a cushion layer disposed about the lead (Pb) barrier layer where the cushion layer includes crosslinked polyethylene (XLPE); and metallic armor wrapped about the cushion layer.
