The electric heating cable converts electric energy into heat energy, and through direct or indirect heat exchange, supplements the heat loss of equipment such as heated pipes, so as to realize the normal working requirements of heating, heat preservation or antifreeze. According to their structure, function and use, they can be divided into many types. Below is a brief description of the different types of electric heating tape.

The following are common types of heating cables and their characteristics:

1. Constant power electric heating cable: This electric heating cable will not change power with the change of ambient temperature, it can maintain a constant heating temperature, suitable for some occasions that need to be heated for a long time, such as factory production lines, warehouses, etc.

2. Self-regulating electric heating cable: This electric heating cable can automatically adjust the heating temperature. When the temperature is too high, it will automatically reduce the power to prevent dangers such as fire caused by overheating. When the temperature is too low, the output power will be automatically increased. Suitable for heat tracing in various complex environments.

3. Mineral insulated heating cable: The insulation layer of this electric heating cable is made of mineral materials such as magnesium oxide. It has the characteristics of high temperature, fire protection, and waterproof. It is suitable for some high temperature, high humidity, flammable and explosive occasions, such as Petrochemical industry, food industry, etc.

4. Series heating cable: This kind of heating cable is suitable for some long-distance and high-power heating occasions, such as large factories and warehouses.

5. Parallel electric heating cable: This electric heating cable is composed of multiple heating cables connected in parallel, each heating cable can work independently, and is suitable for multiple pipes or equipment that need to be heated at the same time.

6. Solar electric heating cable: This electric heating cable uses solar energy for heating, and is suitable for occasions that require a lot of heat energy, such as agricultural greenhouses, swimming pools, etc. Its characteristic is that it can realize energy recycling and has the advantages of environmental protection and energy saving.

When choosing electric heating cables, it is necessary to choose different types of electric heating cables according to different occasions and needs. At the same time, when installing and using, it is also necessary to pay attention to safety and standard operation to ensure its normal operation and service life.
