METHOD OF OPERATING AN ELECTRICAL HEATING ARRANGEMENT
A method of operating an electrical heating arrangement of considerable length using a heating line having at least one heating conductor surrounded by an insulation resistant to high temperatures. A metal tube (4) abutting against the insulation (3) is formed around the heating line (1) and the hea...

| description | A method of operating an electrical heating arrangement of considerable length using a heating line having at least one heating conductor surrounded by an insulation resistant to high temperatures. A metal tube (4) abutting against the insulation (3) is formed around the heating line (1) and the heating line (1), which is equipped with the metal tube (4) is inserted into a metallic tube (5) which has a diameter larger than the metal tube (4) and encloses, in addition to the heating line (1), an axially continuous clearan ce space (6). A non-combustible gas having a lower kinematic viscosity compared with air is inserted into the clearance space (6), said gas completely filling the latter and being kept permanently under pressure. |
