The enclosure shell can be made of various materials with sufficient mechanical strength; the color of the enclosure shell should harmonize with the surrounding environment; the slope of the enclosure top cover shall be no less than 3 degrees, and a rainproof eave should be installed. A louvered vent should be provided at the inner top of the enclosure to ensure natural ventilation.
The bottom of the enclosure features an effective seal to prevent small animals from entering the enclosure through the cable trench. The enclosure is equipped with a dedicated grounding conductor connected to the grounding grid. Inside the enclosure is installed a UN3 series ring main unit.
