Product Description

Single Phase Oil Immersed Transformer
A single-phase transformer is a static electrical device that transfers alternating current (AC) power between circuits through electromagnetic induction, primarily used to step up or step down voltage levels while maintaining frequency. Widely utilized in residential, commercial, and light industrial applications, it enables efficient power distribution and voltage adaptation for diverse electrical systems.
Key Features:
- Core Design: Constructed with high-grade laminated silicon steel cores to minimize energy loss and reduce noise.
- Cooling Methods: Available in oil-immersed (using mineral oil for insulation and cooling) or dry-type (air-cooled) designs, catering to indoor/outdoor environments.
- Voltage Flexibility: Supports standard voltage ratios like 10kV/0.4kV or 11kV/415V, with ±5% voltage adjustment via tap changers.
- Certifications: Compliant with IEC 60076, UL 506, and CE standards, ensuring global market compliance and safety.
Applications:
Ideal for rural electrification, solar/wind energy systems, small-scale industrial machinery, and commercial building power distribution. Its compact design and adaptability make it suitable for regions with limited grid infrastructure.
Advantages:
- Energy Efficiency: Meets Class I/II energy efficiency (DOE/MEPS) standards, reducing operational costs.
- Durability: Sealed oil-immersed models (IP55-rated) resist moisture and contaminants, ensuring 20+ years of service life.
- Customization: OEM support for terminal configurations, enclosures, and accessories.
