Product description

Highlights at a glance

  • Official Level 3 Energy Efficiency, Significantly Reducing Operating Costs: This series of products strictly complies with the GB20052-2024 Level 3 energy efficiency standard. Through optimized magnetic circuit design, no-load loss is only 150W, and load loss is as low as 1580W. Extremely low loss not only means greater environmental friendliness but also saves customers significant electricity costs over long-term operation, making it a cost-effective green energy choice.
  • Fully Sealed Corrugated Tank, Achieving Lifetime Maintenance-Free Operation: Utilizing an advanced fully sealed corrugated tank structure, the transformer oil is completely isolated from external air. This design effectively prevents moisture and oxygen intrusion that leads to oil aging, greatly extending the service life of the insulation materials. During normal operation, no core removal inspection or oil change maintenance is required, making it particularly suitable for use in remote areas.
  • Excellent Harmonic Suppression, Ensuring Power Grid Quality: Employing the Dyn11 connection group, it effectively suppresses the impact of 3rd, 9th, and other higher harmonics on the power grid. Even under heavy three-phase unbalanced loads on the low-voltage side in rural areas, it maintains stable voltage output, protecting precision equipment from harmonic interference.
  • Specifically designed for harsh outdoor environments, with targeted enhancements for rural and outdoor installation conditions: Moisture and corrosion resistant: The surface uses high-performance anti-corrosion paint, resistant to salt spray and damp heat. Strong weather resistance: Seals use high-quality silicone rubber, maintaining good elasticity and sealing performance even under extreme temperature differences. High protection level: Compact structure effectively resists wind, sand, and rain erosion.

    Frequently asked questions

    The S13 series is an upgraded version of the S11. Its core advantage lies in lower losses. According to standards, the no-load loss of the S13 is reduced by an average of approximately 25% compared to the S11. This means that when the transformer is not connected to a load, it consumes less electricity, significantly saving end-users long-term operating electricity costs.

    Fully sealed means that the inside of the transformer tank is completely isolated from the outside air. This prevents moisture and oxygen in the air from entering the tank and causing oxidation and dampness in the transformer oil. For users, the biggest benefit is maintenance-free operation-usually no filtering or replacement of the transformer oil is required during the product's lifespan, greatly reducing maintenance costs in remote areas such as rural power grids.

    Dyn11 is currently the internationally recommended connection method. It boasts exceptional resistance to unbalanced loads. In rural or residential power supply systems, three-phase loads are often unbalanced. The Dyn11 effectively neutralizes neutral current and suppresses high-order harmonics (such as the 3rd harmonic), ensuring stable output voltage and protecting user equipment.

    Yes. Our S13 series is specifically designed for outdoor weather resistance. The corrugated tank provides excellent heat dissipation compensation, adapting to significant environmental temperature differences. Simultaneously, the tank surface employs a multi-layer anti-corrosion coating process, effectively resisting salt spray, UV rays, and high humidity environments, making it ideal for harsh climates.
