As a kind of antifreeze and heat preservation product, the waterproof performance of electric heating cable has always been an important measure to check whether its safety is qualified. Most customers do not have a special understanding of electric heat tracing itself in the process of using electric heat tracing. In some environments, the characteristics of electric heat tracing itself are not considered, which may affect the service life of electric heat tracing cables, such as in humid environments. Will it affect the service life of the electric heating cable?

       When the electric heating cable is used in a humid environment, it needs to be waterproof and insulated. From a safety point of view, once the rainwater penetrates into the layer, the thermal insulation capacity will be greatly reduced. If the sheath is damaged, it may cause electrical breakdown, sparks or dark spots. fire. After the insulation test is qualified, the insulation layer and waterproof layer should be installed as soon as possible, and the insulation layer can be made of ordinary rock wool or perlite or silicate. Moisture in the air After the electric heating cable is installed, it is usually necessary to make a waterproof waterproof layer (mainly using aluminum skin) to ensure that the electric heating cable works in a dry environment.

       The anti-corrosion and explosion-proof electric heating cable is completely suitable for dangerous and corrosive areas, and humidity has little effect on the service life of the heating cable. For humid environments, it is more secure to use double-insulated electric heating cables. Relatively speaking, the biggest damage to the surface of the electric heating cable is ultraviolet rays, which will accelerate the aging of the outer sheath. Therefore, installing the thermal insulation layer and the waterproof layer is also a problem to avoid the electric heating cable being exposed to the sun.
