FIELD: electricity. ^ SUBSTANCE: invention is related to the field of electricity, in particular to heating elements, and may be used, for instance in antiicing systems of aircrafts. Electric heating element comprises woven cloth, made of crossing rows of warp and weft threads, in which at least warp threads are made of electroconductive material with formation of rippling in plane, which is perpendicular to cloth, by means of rounding of one or several rows of dielectric thread of weft on heated side of cloth. Corrugation of electroconductive warp threads is arranged with displacement along cloth relative to rippling in neighboring rows. Dielectric threads of weft are made, for instance from glass fibre. Ends of electroconductive threads of warp are connected by means of electroconductive busbar. Electroconductive threads of warp are fixed by weft threads on substrate, which is made of heat insulating technical cloth, or are woven together with substrate, for instance by means of double plaiting. ^ EFFECT: improved reliability. ^ 8 cl, 5 dwg |
