Description

Technical field[0001]The invention relates to the technical field of electric tracing cables, in particular to an electric tracing cable that can effectively prevent leakage.Background technique[0002]The electric heating cable is composed of a conductive polymer, two parallel metal wires and an insulating sheath. The characteristic is that the conductive polymer has a high positive temperature coefficient characteristic, and they are connected in parallel, and can automatically adjust the output according to the temperature of the heated system. Power, automatically limit the heating temperature, can be arbitrarily shortened or extended to use within a certain range, and allow multiple overlapping without high temperature hot spots and burning concerns;[0003]The existing electric heating cable has poor anti-aging performance, which affects long-term use. At the same time, its mechanical properties, insulation properties and flame retardancy are poor, so a new type of electric heatin...
