Product Description
CHBEB's single-phase pole-mounted transformers, meticulously engineered by Daelim, are essential solutions for stepping down utility distribution voltages from a broad range of 2400V to 34,500V to more user-friendly voltages. While some models are specifically designed for commercial and industrial applications requiring voltages such as 277V, 240/480V, 2400V, and 4800V, the predominant focus is on transforming voltages to a standard single-phase 120/240V. These adaptable transformers are crucial components in small substations, various demanding applications, and are even suitable for voltage step-up operations, ensuring smooth and efficient energy distribution.
CHBEB takes pride in offering two exceptional types of single-phase pole-mounted transformers: the classic conventional model and the cutting-edge Completely Self-Protected (CSP) version, both delivering power ratings up to an impressive 167kVA. These transformers embody the pinnacle of reliability and exceptional efficiency.
Key Features:
- High Efficiency: Rigorously adheres to DOE Energy Efficiency Standards while surpassing the stringent ANSI/IEEE and CSA benchmarks, redefining the benchmarks of exceptional performance.
- Standard Features: Comes with ISO 9001 quality certification, ensuring adherence to the highest manufacturing standards. Features include lifting lugs, arrester mounting pads, resilient high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and essential low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are equipped with an array of advanced protective features such as primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all meticulously designed to ensure the safety and longevity of the transformer.
- Durability and Safety: Outfitted with an innovative self-venting and resealing cover assembly, this feature guarantees the transformer's extended lifespan and consistent reliable operation, providing robust protection for your investment.
Operating Environment:
- Ambient Temperature: Expertly designed to operate efficiently within a temperature range from a maximum of +40°C down to a minimum of -15°C.
- Altitude: Engineered for peak performance at altitudes not surpassing 1000m, ensuring optimal functionality.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Expertly crafted to withstand seismic forces up to 8 degrees, guaranteeing stability and safety in challenging conditions.
- Installation Conditions: The installation site must be devoid of fire risks, explosion hazards, severe vibrations, chemical exposure, and significant pollution to ensure unmatched performance.
