Heating cable comprising steel monofilaments

摘要

A new heating cable is described. The heating cable is comprising between seven and two hundred metallic monofilaments of a first type which are acting as electrical conductors to generate heat. The metallic monofilaments of a first type are having a diameter ranging from 30 μm to 100 μm. The metallic monofilaments of a first type are having a substantially round cross section. The metallic monofilaments of a first type are comprising a steel layer with a chromium content of less than 10% by weight. The heating cable is having an electrical resistance ranging between 0.1 Ω/m and 20.0 Ω/m when measured at 20° C.

1. A heating cable comprises between seven and two hundred metallic monofilaments of a first type, which are electrical conductors configured to generate heat,
wherein the metallic monofilaments of a first type have a diameter between 30 μm and 100 μm, wherein the metallic monofilaments of a first type have a substantially round cross section, wherein the metallic monofilaments of a first type comprise a steel layer with a chromium content of less than 10% by weight; wherein the metallic monofilaments of a first type comprise a corrosion resistant coating layer; wherein the heating cable comprises a metallic monofilament of a second type or one or more bundles of metallic monofilaments of a second type; and wherein the metallic monofilament of the second type differs in composition from the metallic monofilament of the first type; and wherein the heating cable has an electrical resistance ranging between 0.1 Ω/m and 20.0 Ω/m when measured at 20° C.
