The use of electric heating cables in wind power blade deicing is as follows:

1. Determine the deicing plan: According to the structure of the wind power blades and the deicing requirements, formulate a reasonable deicing plan. Considering the shape and curvature of the blades, you can choose to use straight or spiral heating cables.

2. Install the electric heating cable: according to the deicing plan, install the electric heating cable at the proper position of the blade. The electric heating cable can be fixed on the surface of the blade with adhesive tape or special fixing parts to ensure that the electric heating cable will not fall off.

3. Connect the power supply: connect the output end of the heating cable to the power supply for heating and deicing.

4. Adjust the temperature: according to the blade material and deicing requirements, properly adjust the temperature of the heating cable. If the deicing requirements are high, the heating power of the electric heating cable can be increased or the heating time can be extended.

5. Deicing operation: start the power supply, let the electric heating belt heat the blades, and melt the ice and snow. Deicing can be assisted by special deicing tools or high-pressure water guns.

6. Maintenance and maintenance: Regularly check the operation status of the electric heating cable, and repair it in time if any fault is found. In the non-deicing season, the power can be turned off, but the performance and aging of the electric heating cable need to be checked regularly to ensure its normal operation.

Through the above steps, the electric heating cable can be used to de-ice the blades of wind power generation. The use of electric heating cable for deicing can not only improve the deicing efficiency, but also reduce the cost of manual deicing and ensure the normal operation of wind power generation equipment. At the same time, it is necessary to pay attention to the installation and use of electric heating cables to avoid safety problems caused by improper operation.
