Abstract

A compacted mineral insulated integrally sheathed electrically conductive cable utilizing nickel-base alloys includes at least one thermoelement (a) composed of a type N alloy (defined below), and its sheath (b) is composed of an alloy having similar characteristics to the alloy of which the or at least one thermoelement is composed. The electrically conductive cables include thermocouple cables; thermocouple sensors can be made from said thermocouple cables, as can heat detectors, resistive heating elements, and stagnation temperature probes (Fig. 2). Positive type N alloys include, in weight percentages, Cr(14.2 +/- 0.15), Si(1.4 +/- 0.05), Fe(0.1 +/- 0.03), C(0.03 max), Ni(balance). Negative type N alloys include Cr(0.02 max), Si(4,4 + 0.2), Fe(0.1 + 0.)3), C90.03 max), Mg (0.1 +/- 0.05), Ni(balance). <IMAGE>
