Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously designed by Daelim, play a crucial role in reducing utility distribution voltages from a broad range of 2400V to 34,500V down to user-friendly levels. While some units are engineered for commercial and industrial voltages, such as 277V, 240/480V, 2400V, and 4800V, the majority focus on converting to a single-phase 120/240V. These adaptable transformers are indispensable in small substations, diverse applications, and even scenarios requiring voltage step-up, ensuring smooth and reliable energy distribution.
CHBEB is proud to present two exceptional varieties of single-phase pole-mounted transformers: the classic model and the pioneering Completely Self-Protected (CSP) version, with power capacities reaching up to 167kVA. These transformers exemplify superior reliability and efficiency.
Key Features:
- High Efficiency: Conforms with DOE Energy Efficiency Standards and surpasses ANSI/IEEE and CSA criteria, establishing a new benchmark for outstanding performance.
- Standard Features: Incorporates ISO 9001 quality certification, ensuring premier manufacturing standards. Features include lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and crucial low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: CSP models include 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 crafted to protect the transformer.
- Durability and Safety: Equipped with a state-of-the-art self-venting and resealing cover assembly, this feature ensures the transformer's enduring and reliable performance, protecting your investment for years to come.
Operating Environment:
- Ambient Temperature: Engineered to perform efficiently in temperatures ranging from a maximum of +40°C to a minimum of -15°C.
- Altitude: Designed to operate optimally at heights not exceeding 1000m above sea level.
- Humidity:
- Daily average relative humidity should not exceed 95%.
- Monthly average relative humidity should not exceed 90%.
- Seismic Intensity: Skillfully constructed to endure seismic forces up to 8 degrees, ensuring both stability and safety.
- Installation Conditions: The installation location must remain free from fire hazards, potential explosions, intense vibrations, chemical exposure, and heavy pollution to ensure optimal performance.
