Abrégé

The invention concerns an electric heating cable intended for pipelines. Sections (11a, 12a and 13a) of three phase conductors (11, 12 are 13) are stripped respectively. These sections are intended to be installed and both secured in place and electrically connected to each other inside a box (14) having, for example, a central cavity (15) having a rectangular cross-section, the depth of which is at least equal to the length of the stripped sections (11a, 12a and 13a) and the length of which is preferably greater than the transverse cross-section of these stripped sections of the phase conductors. They are secured in the central cavity (15) with a conductive binder (16), for example a tin solder, in order to ensure they are secured in place and electrically connected to each other.

Abrégé

The invention relates to an electric heating cable which is to be inserted into ducts or tanks for water or any other food material. For this purpose, the cable (10) comprises at least one conductive core (11) embedded in at least one peripheral insulation layer (12). Said peripheral insulation layer (12) is made of a fire-resistant polymer and is coated with a final outer sheath (13) made of a polymer compatible with water, in particular with drinking water, such as polyethylene.

Abrégé

The invention relates to an electrical cable (10) for AC current having high voltages greater than 2 KV and/or working at high temperatures of the order of 260°C, and/or used in a specific environment, in particular aeronautical. This cable (10) is designed to push back the limit conditions of the corona effect. For this purpose, it comprises a conducting core (11) and an outer insulating sheath (13) surrounding the conducting core (11) as well as a single semiconducting primary layer (14) interposed between this conducting core (11) and the insulating outer sheath (13). The single semiconducting primary layer (14) is extruded and made of fluoropolymer filled with carbon black.
