| description | The invention relates to a heat tracing power cable, and belongs to the technical field of cables, the heat tracing power cable comprises a PTC core belt, an insulating layer and a sheath layer, the interior of the heat tracing power cable is protected by improving the performance of the sheath layer, a reactive additive is added when a sheath material of the sheath layer is prepared, and the reactive additive and raw materials are mixed or extruded in the blending or extruding process, so that the heat tracing power cable is formed. On one hand, the dispersion compatibility of an inorganic mixture in a matrix can be improved, and the flame retardance and the mechanical property of the sheath material are improved at the same time; on the other hand, the cross-linked structure serves as a part of the sheath material and is good in combination effect, meanwhile, hydroxyl of the reactive additive can be cross-linked to form a continuous structure which is hydrophobic, the reactive additive is matched with a per |
