Working environment of dry-type transformers
Dry-type transformers are suitable for working in an environment of 1.0-40℃, and the relative humidity must be controlled below 80%.
Altitude is limited to 2500 meters to ensure the normal operation of the transformer.
The transformer must be protected from rain, moisture, high temperature, high heat or direct sunlight, and its heat dissipation vents should be kept at least 40cm away from surrounding objects.
The transformer should be kept away from corrosive liquids, gases, dust, conductive fibers or metal shavings to prevent damage.
Prevent the transformer from working in places with severe vibration or electromagnetic interference to ensure its stability.
The transformer should avoid inversion and strong impact during long-term storage and transportation to protect its structural integrity.
