Products Description
30-2500KVA Epoxy Resin Cast Dry-Type Transformer adopts a three-phase design with a rated capacity range of 30-2500kVA, high-voltage side ≤35kV, low-voltage side 0.4kV, compliant with IEC standards (insulation class F/H). Featuring epoxy resin vacuum casting technology, its sealed coils are flame-retardant, moisture-proof, and pollution-resistant, eliminating fire hazards and suitable for flammable, humid, or corrosive environments. It boasts high mechanical strength, short-circuit resistance, low partial discharge (≤5pC), and supports short-term overload up to 50%. Integrated with an intelligent temperature control system for real-time monitoring and regulation, combined with low-loss, low-noise design, it ensures maintenance-free and cost-effective operation. Widely used in industrial parks, commercial complexes, hospitals, airports, and other sites with stringent demands for power supply safety and stability.

Epoxy Resin Cast Dry-Type Transformer Products Description
1. Structural & Material Advantages
• Solid Insulation, Oil-Free Design: Utilizes epoxy resin vacuum casting technology instead of traditional oil-immersed insulation.
• Fire & Explosion-Proof: No flammable materials, safe for high-risk environments (e.g., underground facilities, data centers), compliant with environmental and fire safety regulations.
• Corrosion & Moisture Resistance: Strong epoxy resin adhesion resists humidity, salt spray, and chemical gases, ideal for harsh industrial environments.
2. Energy Efficiency & Performance
• High Efficiency, Low Loss: Meets IEC 60076 and national energy standards, reducing no-load loss by over 30% for lower operational costs.
• Superior Temperature Control: Excellent heat dissipation with Class F (155°C) or H (180°C) insulation materials, ensuring stable long-term full-load operation and enhanced overload capacity.
• Low Noise: Optimized electromagnetic design and damping structures reduce noise by 5-10 dB(A), suitable for noise-sensitive areas.
3. Capacity Features & Applications
Common Capacities:
• 125KVA: Compact design, lightweight (suitable for tight spaces), noise ≤50 dB(A); ideal for commercial buildings, hospitals, schools, and residential power distribution.
• 160KVA: Optimized cooling for -30°C to +50°C environments, supports frequent load switching; used in workshops and small/medium factory power systems.
• 200KVA: High load stability with short-term overload up to 150%, integrated smart temperature control; perfect for data centers, subway stations, and commercial complexes.
• 250KVA: Reinforced winding structure (strong short-circuit resistance), optional remote monitoring; deployed in industrial plants, high-rise buildings, and regional substations.
4. Maintenance & Economic Benefits
• Maintenance-Free: No oil replacement or leakage checks required, reducing lifecycle costs by 30%.
• Long Lifespan: Operational life ≥25 years with slow insulation aging and strong corona resistance.
• Modular Installation: Compact design enables quick on-site setup, saving civil engineering costs (e.g., no oil pit needed).
