Electric heating cables are mainly used in antifreeze and heat preservation of pipelines, storage tanks, valves, pump bodies, containers, and instruments in the fields of petroleum, chemical industry, electric power, fire protection, metallurgy, steel, pharmaceuticals, food, and ships. When using the electric heating cable, it needs to be selected according to the environment, temperature, medium, structure and use of the site. In the face of a wide variety of electric heating cable products, they can be classified according to different classification criteria.

According to different usage scenarios and needs, electric heating cables can be divided into many different categories. First of all, according to the shape and structure of the electric heating cable, it can be divided into two types: strip electric heating and sheet electric heating. Strip-shaped electric heat tracing usually uses strip-shaped electric heat tracing materials, which can be cut and installed according to needs, and are suitable for heating objects of various shapes and sizes. The sheet-shaped electric heat tracing uses sheet-shaped electric heat tracing materials, which can be spliced and assembled according to needs, and is suitable for large-area heating needs.

Secondly, according to the power and temperature control methods of electric heating cables, they can be divided into two types: constant power electric heating and constant temperature electric heating. Constant power electric heat tracing is usually controlled by a controller, and the heating power can be adjusted according to needs, which is suitable for occasions that require rapid heating. The constant temperature electric heat tracing is controlled by a constant temperature controller, which can accurately control the heating temperature, and is suitable for occasions that need to maintain a constant temperature.

In addition, according to the material and application of the electric heating cable, it can be divided into various types such as silicone electric heating, glass fiber electric heating, and ceramic electric heating. Silicone electric heating has the advantages of good flexibility, high temperature resistance, corrosion resistance, etc., and is suitable for heating objects of various shapes and sizes. Glass fiber electric heat tracing has the advantages of high temperature resistance, corrosion resistance, good insulation performance, etc., and is suitable for heating needs in high temperature environments. Ceramic electric heat tracing has the advantages of high temperature resistance, corrosion resistance, and good thermal conductivity, and is suitable for heating needs of high temperature and high viscosity liquids.

Finally, according to its use place and form, it can be divided into household electric heating cables and industrial electric heating cables according to the use places, and can be divided into wall-mounted, column-type, hanging-type, roller-shutter and so on according to the form. Various types. Household electric heating cables are widely used in daily life and can be used in small areas such as bedrooms and living rooms. Industrial electric heating cables have relatively large power, which can reach tens of kilowatts, and are usually used in large-scale places such as large factories and workshops.

To sum up, there are various classifications of electric heating cables, and different classification methods are suitable for different usage scenarios and needs. In practical application, it is necessary to select the appropriate type of electric heating cable according to the specific situation in order to achieve the best heating effect.
