1. About Radiastar Transformer Tanks

Radiastar transformer tanks are designed for durable performance and optimal insulation. They store and circulate insulating oil to maintain core and winding efficiency while providing mechanical protection against external forces. Radiastar ensures compliance with IEC and ANSI standards for global deployment.

With a focus on customization, Radiastar offers tanks for a wide range of voltages and capacities, from 10kV to 132kV and 3MVA to 100MVA transformers.

2. Types of Transformer Tanks

2.1 Corrugated Transformer Tanks

Corrugated walls enhance mechanical strength and thermal performance, allowing the oil to expand safely. Key benefits include:

• Improved cooling due to increased surface area
• Absorption of oil expansion and contraction
• Reduced maintenance and longer lifespan
• Suitable for high-performance 10kV–33kV transformers

2.2 Conventional Transformer Tanks

Conventional tanks feature flat walls and robust steel construction. Benefits include:

• Cost-effective manufacturing
• Ideal for standard industrial applications
• Supports natural or forced oil circulation for cooling
• Compatible with various medium-voltage transformer models

3. Key Features and Benefits

• Durable Steel Construction: Corrosion-resistant and long-lasting
• Customizable Dimensions: Tailored to transformer specifications
• Efficient Oil Cooling: Optimized design for uniform heat distribution
• Reinforced Lifting Points: Safe transport and installation
• Environmental Adaptation: Suitable for C1–C5 climates
• Compliance: IEC 60076, ANSI C57
