Using vents (such as AttaBox's UL Type 4X Rated Non-Metallic Breather and Drain Vents) can help move air through the enclosure, carrying away any excess moisture and stabilizing the temperature differential. Why should you care? Because those innocent-looking droplets are like ticking time. A distribution box (100) capable of preventing moisture and dew condensation according to the present invention comprises a box-shaped case (110) configured to accommodate a control unit (105), a heating means (120) installed in the case (110) to heat air in the case (110), and a dehumidifier (130). In small power transmission and transformation equipment such as distribution boxes, switchgear,power distribution cabinets, and outdoor terminal boxes, humid air can easily cause rust and corrosion of metal bodies and shorten the service life of the equipment. The insulation distance in the sealed. Condensation occurs when warm, humid air comes into contact with a cold surface. While this might not seem like a big deal, inside electrical enclosures, it can cause real trouble—like short circuits, rust, and equipment failure.
