Product Description
CHBEB's single-phase pole-mounted transformers, meticulously designed and engineered by Daelim, are essential power solutions for efficiently stepping down utility distribution voltages from 2400V to 34,500V to more user-friendly utilization levels. While a specialized selection caters to commercial and industrial needs with voltages like 277V, 240/480V, 2400V, and 4800V, the primary focus remains on transforming to a single-phase 120/240V voltage. These adaptable transformers play a pivotal role in small substations and diverse applications, including voltage step-up uses, ensuring consistent and reliable energy distribution.
CHBEB proudly presents two unique types of single-phase pole-mounted transformers: the conventional model and the pioneering Completely Self-Protected (CSP) version, each offering power ratings up to 167kVA. These transformers exemplify the highest standards of reliability and efficiency, making them an ideal choice for diverse energy needs.
Key Features:
- High Efficiency: Compliant with DOE Energy Efficiency Standards and surpassing ANSI/IEEE and CSA guidelines, these transformers set a new benchmark for outstanding performance.
- Standard Features: Includes ISO 9001 quality certification, confirming premium manufacturing standards. The design features lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and essential low-voltage neutral grounding straps, ensuring comprehensive functionality.
- Self-Protected (CSP) Design: The CSP models are equipped with a suite of protective features such as primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all meticulously integrated to ensure superior transformer protection.
- Durability and Safety: Featuring an innovative self-venting and resealing cover assembly, this component delivers exceptional longevity and consistent reliable operation, ensuring your investment is safeguarded over time.
Operating Environment:
- Ambient Temperature: These transformers are crafted to perform optimally in temperatures ranging from a maximum of +40°C to a minimum of -15°C.
- Altitude: Designed to operate efficiently at altitudes up to 1000 meters, ensuring adaptability to diverse geographic locations.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Engineered to endure seismic forces of up to 8 degrees, ensuring stability and safety even in challenging conditions.
- Installation Conditions: For optimal performance, the installation site should be devoid of fire hazards, potential explosions, severe vibrations, chemical exposure, and significant pollution.
