| ●When the environmental humidity on the application site is relatively high, especially when there is condensation phenomenon, such as the distribution cabinet equipment used for gold, aluminum, and phosphate ore in non-ferrous metal mines, which is used below the ground, integrators or users need to handle the electrical control cabinet, such as strengthening the IP protection level of the electrical control cabinet, installing humidity heating controllers inside the electrical control cabinet, and reasonably adding some moisture-proof desiccants to handle it. |
