Description

1250KVA Dry Type Transformer

Our 1250KVA dry-type transformer features a fully enclosed design with IP54 protection rating, effectively preventing dust and moisture intrusion to ensure stable operation in harsh environments. Utilizing Class H insulation materials with a temperature resistance of 180°C, it significantly extends equipment service life.

The compact structure saves installation space, making it particularly suitable for confined electrical rooms. The surface is treated with environmentally friendly coating offering excellent corrosion resistance and aesthetic appeal. Operating at below 60 dB noise level, it far exceeds national standards, creating a quiet working environment. Our transformer is especially ideal for hospitals, schools, commercial centers and other applications demanding highest safety and reliability requirements.
