Electric heat trace uneven hot and cold failure
Reason: The insulation layer is not waterproof, and the insulation layer is immersed in water in rainy and snowy days, so that the electric tropical part of the electric tropical section is output with large power in a low temperature or humid state for a long time, resulting in uneven attenuation rate or excessive speed attenuation; No insulation layer or uneven thickness of insulation layer; After the period of use, this situation generally decreases gradually.
Solution: Install in strict accordance with the requirements of the product instructions, and make a waterproof layer along the whole line of the insulation layer, so that the electric tropics can work in a dry state; View manufacturing dates, useful days, and specifications
