⑴For 2.5 mva power and distribution transformers, the foundation should be elevated 0.2 meters above the ground. In waterlogged areas, a drainage channel should be provided around the transformer. A brick or stone enclosure wall should be erected around the 2.5 mva power and distribution transformer, with a minimum height of 1.8 meters. The enclosure wall's door should be made of fire-resistant materials, located on the low-voltage side of the 2.5 mva power and distribution transformer, should open outward, and should be equipped with a lock. Bamboo or wooden fences should not be used.
⑵2.5 mva power and distribution transformers installed on platforms or pedestals should have a minimum height of 2.5 meters.
⑶When outdoor, if two or more 2.5 mva power and distribution transformers are installed, the minimum distance between their casings should be no less than 1.25 meters.
⑷The 2.5 mva power and distribution transformer casing should be well-maintained.
⑸The distance between the transformer and flammable buildings should not be less than 5 meters, and the distance from fire-resistant buildings should not be less than 3 meters.
⑹Install a warning sign on the enclosure wall or pedestal stating "Caution: High Voltage - No Entry" in English.
