Abstract

The invention discloses a single-conductor flexible high temperature heat tracing cable and relates to the technical field of a cable, in particular to a flexible high temperature heat tracing cable. The single-conductor flexible high temperature heat tracing cable comprises an insulated conductor. A heating body, an undersheath layer, a shielding layer and an outer sheath layer are sequentially arranged outside the insulated conductor. The insulated conductor comprises silver plated copper wires. An insulating layer is coated outside the silver plated copper wires. The single-conductor flexible high temperature heat tracing cable is uniform to emit heat, has ultralow full-length temperature difference, has low temperature resistance and high heating power, and is suitable for an industrial pipeline to convey crude oil, liquid industrial chemicals and industrial water.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a flexible high-temperature heating cable. Background technique

[0002] With the development of industrial pipeline transportation technology, long-distance transportation of crude oil, liquefied chemical raw materials and industrial water has become more and more common. At the same time, pipeline transportation technology is used in power plants, kerosene plants, water treatment workshops and food processing departments to replace machinery Transportation, too, is becoming more and more popular. And this kind of pipeline is generally all outdoors, when the conveying liquid is lower than a certain temperature, not only the viscosity is higher, sometimes also solidify, so the problem of antifreeze and heat preservation has just been raised. The antifreeze and heat preservation of short-distance pipelines can be protected by steam, but this method is not only labor-intensive and ...
