Key features and application of Cast Resin Dry Type Transformer
• Core Features:
• 1. No insulating oil; relies on air convection/forced air cooling, with windings fully encapsulated in epoxy resin;
• 2. Fire-resistant, flame-retardant, explosion-proof, maintenance-free, no risk of oil leakage, very high operational safety;
• 3. Moisture-proof, dust-proof, resistant to humid environments, low partial discharge, low noise;
• 4. Higher cost than oil transformers, larger volume for the same capacity, short-term overload capability is weaker than oil transformers.
• Applicable Scenarios:
• - Indoor distribution rooms, high-rise buildings, shopping malls, hospitals, schools, subways, tunnels;
• - Data centers/computation centers, computer rooms, precision instrument workshops (core selection for IDC);
• - Chemical, oil and gas plants, flammable and explosive areas, underground pipelines, enclosed spaces;
• - Public buildings with high population density and strict fire protection requirements.
