IEC standard 30kva 10/0.4Kv dry type transformer.
Dry-type power transformers adopt special process technology to ensure products fully meet requirements such as fire prevention, waterproof, and environmental protection.
By optimizing the structure of the high-voltage coil, the series improves the distribution of voltage and capacitance between layers, enhancing the product's ability to withstand atmospheric overvoltage, operating overvoltage, and electric field distribution.
It is an ideal product for distribution systems, widely used in subways, shipbuilding, mining, chemical industries, power systems, and personnel-intensive buildings where safety is paramount.
