SG(B) Series Non-Encapsulated Dry-Type Transformer

Key Features

1. H-Grade Insulation System: Equipped with DuPont NOMEX® paper as the main insulation, achieving H-grade (180°C) heat resistance and Class C (200°C) key part rating. Non-flammable, self-extinguishing, and non-toxic, it produces virtually no toxic smoke even after prolonged 800°C combustion.

2. Superior Reliability & Excellent three-proof performance: Excellent moisture, mold, and salt fog resistance. Withstands thermal shock and cracking, ensuring long-term stability in harsh indoor environments.

3. High Overload Capacity: Equipped with high overload capability and fast heat dissipation. It can operate safely and reliably for long periods under 130% overload, meeting high-demand industrial and emergency power needs.

4. Eco-Friendly Design: Manufactured, transported, stored, and operated without environmental pollution. Materials are recyclable at end-of-life, supporting green energy initiatives.

5. Robust Ventilation: Non-encapsulated structure ensures optimal natural/forced air cooling, maintaining high efficiency and low noise operation.

Technical Specifications

Operating Conditions

• Standard Altitude: ≤ 1000m
• Ambient Temperature: -25°C ≤ Temperature ≤ 40°C
• Installation Environment: Indoor use with good ventilation. For basements or poorly ventilated areas, additional heat dissipation devices are required.
• Special Adjustment: For altitudes > 1000m, ambient temperature > 40°C, or < -25°C, adjust rated values per GB/T 1094.11 standards.

Applications

• High-Density Areas: High-rise residential, airports, stations, subways, hospitals, and water source reservoirs.
• Critical Infrastructure: Power plants, nuclear power plants, military facilities, and petroleum/chemical industries.
• Commercial & Industrial: Shopping centers, metallurgical industries, and data centers requiring reliable, low-pollution power distribution.
