This enclosed cast-resin dry-type transformer is a fully integrated power distribution solution, housed in a sleek, all-white metal cabinet with transparent viewing panels and ventilation grilles, designed for safety and visual clarity. Inside, three bright red epoxy-resin encapsulated windings with high-voltage warning labels are mounted on a robust blue structural frame, paired with silver cooling systems for efficient thermal management. Built with eco-friendly, flame-retardant materials and non-toxic epoxy resin, this three-phase unit eliminates oil-related hazards, offers low-noise operation, and meets IEC and GB standards with customizable capacities (100kVA–8000kVA) and voltage levels up to 35kV. The fully enclosed design protects against dust, moisture, and physical damage, requiring minimal maintenance—only periodic visual inspections and filter cleaning, with no oil changes needed. We offer full customization, including cabinet configurations, connection types, and cooling options (natural/forced air), to match your exact application needs, making it ideal for indoor commercial buildings, data centers, hospitals, and industrial facilities.
These dry-type transformers deliver factory-direct pricing, end-to-end support including on-site installation guidance and long-term technical assistance, and fast global delivery for projects of all sizes.

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.
