Water can damage the coating on the surface of the product, accelerate metal corrosion, and reduce the strength of certain materials. It is the main cause of electrical insulation flashover or breakdown, resulting in short circuit damage to the product; water will also penetrate into the product and will freeze, Cause parts to malfunction or fail due to blistering or rupture; water can also cause high humidity, thereby promoting mold growth.
