Power distribution equipment should be stored in a warehouse that is dry, well-ventilated, free of corrosive gases, low in dust, and maintained at an appropriate temperature; direct sunlight, high temperatures, humidity, or frost must be avoided to prevent damage to the equipment. For equipment stored outdoors, protective coverings or shelters-designed to guard against rain, dust, and ultraviolet radiation-should be installed to ensure the equipment maintains its physical integrity and insulation performance over the long term.
Equipment should be stacked in a systematic and rational manner. Heavy-duty distribution equipment must be placed on a sturdy, level surface or on pallets to prevent direct contact with ground moisture. When stacking, adequate spacing should be maintained to facilitate ventilation and inspection, while avoiding excessive stacking heights that could lead to deformation or structural damage. Fragile or precision components should be packaged separately or provided with reinforced protection to prevent impact damage during transport or handling. Regular visual inspections should be conducted on busbars, switches, circuit breakers, and insulation components to ensure there are no signs of corrosion, dust accumulation, or insulation degradation. For equipment intended for long-term storage, appropriate anti-rust treatments may be applied; furthermore, equipment records and identification labels should be kept clear and legible to facilitate subsequent allocation, installation, and utilization.
