Product Narrative
Application fit, product overview, key features, and selection value are presented in one product narrative.
Product Positioning
This combined transformer is built for wind-power projects that need reliable step-up and distribution equipment while balancing capital investment and operating cost.
Product Overview
To support the rapid growth of wind power, the product provides both 12kV and 40.5kV voltage classes and uses more energy-efficient design and manufacturing solutions to reduce substation cost for the user.
Product Features
- Split-box structure places high-voltage components in two independent enclosures for easier maintenance and cleaner oil conditions.
- Loop-network capability with at least two high-voltage incoming and outgoing circuits.
- Additional cable branch-box function for more circuits in 12kV models.
- 40.5kV models can use high-voltage current-limiting fuses for full-range protection.
- Optional stainless-steel enclosure with sandblasting, hot-dip galvanizing, and painting for strong anti-corrosion performance.
- Fully sealed enclosure with protection level up to IP33~IP54.
Typical Scenarios
It is suitable for wind-farm box-type substations, loop-network access, and outdoor projects that require corrosion resistance, easy maintenance, and multi-circuit flexibility.
Business Value
The product combines energy-saving design, operational safety, and field maintenance convenience, helping wind projects reduce total substation cost while maintaining reliable long-term performance.
