Product Features
Investing in a transformer dry type system from our facility means choosing longevity and intelligent management.
• Superior Thermal Management
Equipped with high-quality copper windings and axial cooling ducts, our dry-type transformer design ensures rapid heat dissipation and prevents localized hotspots.
• Intelligent Monitoring
Integrated temperature control systems feature Pt100 platinum resistors, providing real-time 3-phase scanning, automatic fan activation (at 100°C), and emergency high-temperature trip protection (at 150°C).
• Robust Core Engineering
We utilize 45° full-oblique joints with premium cold-rolled grain-oriented silicon steel. This specific dry type transformer construction minimizes core loss and significantly reduces operating noise.
• Environmentally Resilient
Coated with high-adhesion moisture-proof resin, our units thrive in harsh, humid, or corrosive environments without the risk of leakage associated with oil-filled units.
• Enhanced Overload Capacity
With Force Air Cooling (AF), our units can boost output power by 40%–50%, providing a critical safety margin during peak demand.
As a professional dry type transformer manufacturer and dry type transformer supplier, we ensure every unit undergoes full routine, type, and special tests before delivery, guaranteeing stable and reliable performance.
