Product Accessories

Core System
Design: Features a 45° full bevel joint step-lap core structure made from cold-rolled grain-oriented silicon steel, ensuring low no-load losses and enhanced vibration resistance.
Reinforcement: The core is specially reinforced to maintain structural stability during transportation and operation.

Winding System
High-voltage Winding: Wound with insulated copper wire using patented technology to improve lightning resistance, suitable for voltage levels up to 20kV (customizable to 11kV as per user requirements).
Low-voltage Winding: Constructed with high-quality copper foil, rated Class A insulation, offering high mechanical strength and short-circuit resistance.

Enclosure and Sealing Structure
Sealed Design: Features a fully sealed enclosure welded by ABB robots with laser inspection, achieving a leak point pass rate of 99.99998%. The surface undergoes electrostatic spraying, providing over 100 hours of corrosion resistance and a service life exceeding 30 years.
Safety Features: Equipped with explosion-proof devices (such as pressure relief valves) and oil level indicators to ensure safe operation.

Cooling and Insulation System
Transformer Oil: Utilizes 25# or 40# transformer oil, serving both insulation and cooling purposes.
