Three-Phase Insulation Epoxy Resin Cast Dry Type Distribution Transformers 13.8kV 15.5kV 27kV 34.5kV

• Superior Insulation Performance:This Cast-Resin Distribution Transformer adopts high-quality epoxy resin as the main insulation material, with its windings formed by vacuum casting and high-temperature curing. This advanced process ensures the insulation layer is dense, uniform and bubble-free, enabling the Dry Type Distribution Transformer to effectively resist moisture, dust and chemical corrosion. The excellent insulation performance not only guarantees safe operation under rated voltage, but also enhances the Cast-Resin Distribution Transformer’s partial discharge resistance, significantly extending its service life.
• Oil-Free Dry-Type Design, Safe & Eco-Friendly:Unlike oil-immersed models, this Dry Type Distribution Transformer features a pure dry-type structure without any insulating oil, fundamentally eliminating the risks of oil leakage, fire and environmental pollution. This makes the Cast-Resin Distribution Transformer particularly suitable for fire-sensitive areas such as high-rise buildings, hospitals, data centers, airports and subway stations. Its green and environmentally friendly design fully complies with global environmental protection standards, reducing the environmental impact of the Dry Type Distribution Transformer during operation and disposal.
• Stable & Efficient Operational Performance:The Cast-Resin Distribution Transformer is equipped with high-precision silicon steel sheets for the iron core, which features low loss and high magnetic permeability, effectively reducing no-load loss and improving the Dry Type Distribution Transformer’s energy conversion efficiency. Its three-phase winding adopts a reasonable impedance-balanced design, ensuring stable three-phase current output and minimizing voltage fluctuation. Additionally, the Cast-Resin Distribution Transformer has excellent heat dissipation performance—equipped with axial and radial cooling fins or optional forced air cooling devices, it can quickly dissipate operational heat, maintaining a stable working temperature for the Dry Type Distribution Transformer even under full-load operating conditions.
• Wide Voltage Range & High Customizability:This Dry Type Distribution Transformer covers four rated voltage specifications (13.8kV, 15.5kV, 27kV, 34.5kV), which can be flexibly matched with different medium-voltage power distribution networks. The Cast-Resin Distribution Transformer supports optional customized tap voltage adjustment to adapt to grid voltage changes, ensuring stable power supply for terminal electrical equipment. Its rated capacity can be fully customized according to customer needs, covering a wide range of power levels, and the Dry Type Distribution Transformer can perfectly meet the power distribution requirements of various scale projects.
