Product description:

• Core: Crafted from high-quality cold-rolled grain-oriented silicon steel sheets, the core features a 45° full-bevel joint and a five-step lamination method. This design results in reduced no-load losses and lower noise levels. The core column and the iron yoke both have multi-stage circular cross-section shapes, further enhancing the transformer's efficiency and performance.
• Coil Insulation: The high-voltage conductor utilizes double glass enameled copper wire, while the interlayer insulation is made of H-grade glass fiber cloth and glass felt. This combination provides excellent insulation properties and resistance to sudden short circuits. The low-voltage winding employs copper foil, with interlayer insulation consisting of epoxy resin prepreg cloth, ensuring high mechanical strength and durability.
• Clamps and Structure: The clamps are made of low-magnetic steel pull plates and clamps with matching structures. They are sandblasted and coated with plastic, resulting in a beautiful and robust overall structure with high mechanical strength.
• Flame-retardant and Fire-proof: The epoxy resin encapsulation of the coil offers flame-retardant, fire-proof, and explosion-proof properties, making it suitable for various environments where safety is paramount.
• Low Maintenance and Pollution-free: The design eliminates the need for oil, making it maintenance-free and pollution-free, which is particularly beneficial for urban power grids and environmentally sensitive areas.
• Compact Size: The compact design allows for direct installation in the load center, saving space and facilitating easier integration into existing infrastructure.
• Partial Discharge and Noise: The scientific and reasonable design and casting process result in smaller partial discharge and lower noise levels, contributing to the transformer's reliability and reduced operational disturbances.
• Heat Dissipation: Equipped with an independent axial flow fan for each phase and a split temperature controller, the Dry Type Transformer effectively reduces temperature rise, increases its output capacity, and ensures safe operation.
