The invention belongs to the technical field of electric tracing bands and particularly relates to an electric tracing band capable of effectively preventing the electric leakage. The electric tracingband is provided to solve the following problems in the prior art: the earth leakage protection measures of an existing heat tracing band are relatively simple, the electric leakage of the existing heat tracing band easily occurs, and the normal use of the electric tracing band is influenced. According to the technical scheme of the invention, the electric tracing band capable of effectively preventing the electric leakage comprises an electric tracing band body. The electric tracing band body comprises a copper core wire. The copper core wire is sleeved with a shielding layer. A first protective material layer is arranged between the copper core wire and the shielding layer. The shielding layer is sleeved with an insulating layer. The two sides of the shielding layer are each provided with an anti-creeping wire and an insulating tube. According to the electric tracing band, through cooperation of a multi-layer structure, electric leakage of the copper core wire during working can beeffectively prevented. The electric tracing band body can be cooled and protected. The service life of the electric tracing band is prolonged.
Description
Technical field [0001] The present invention relates to the technical field of electric heating cables, in particular to an electric heating 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. Its characteristic is that the conductive polymer has a high positive temperature coefficient characteristic, and they are connected in parallel, can automatically adjust the output power with the temperature change of the heated system, automatically limit the heating temperature, and can be used in short or extended within a certain range. , And allow multiple overlaps without high temperature hot spots and burning concerns. Since its application in 1971, because the heating power varies with the temperature of the electric heating cable, the heated semiconductor core material has a higher temperature than the heating temperature. / Low variable tempera...
