Why choose dry-type: Safe and environmental friendly transformers
• Reduced environmental contamination
• 0-risk of leakage of flammable or contaminating substances
• Environmentally-friendly production
• Well-suited to dump and contaminated areas
• Non-flammable and self-extinguishing
• High resistance to short circuits
• High capacity to support overloads
• High performance in dealing with seismic phenomenon
• Capable of withstanding the most severe rolling and vibrating conditions
