Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, masterfully engineered by Daelim, are crucial for transforming utility distribution voltages ranging from 2400V to an impressive 34,500V down to more manageable utilization voltages. While a select few are optimized for commercial and industrial voltages like 277V, 240/480V, 2400V, and 4800V, the majority are designed to adeptly convert voltages to a single-phase 120/240V. These adaptable transformers are indispensable in small substations, a myriad of applications, and even voltage step-up scenarios, ensuring uninterrupted and efficient energy distribution.
CHBEB proudly presents two exceptional categories of single-phase pole-mounted transformers: the classic conventional model and the avant-garde Completely Self-Protected (CSP) version, both delivering power ratings up to an impressive 167kVA. These transformers set a benchmark in reliability and performance efficiency.
Key Features:
- High Efficiency: Adheres to the most rigorous DOE Energy Efficiency Standards and exceeds ANSI/IEEE and CSA benchmarks, establishing a new paradigm for performance excellence.
- Standard Features: Features ISO 9001 quality certification, a testament to the highest manufacturing standards. Includes 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: The CSP models are equipped with a suite of protective features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all meticulously designed to safeguard the transformer.
- Durability and Safety: Outfitted with an innovative self-venting and resealing cover assembly, this feature ensures the transformer's longevity and steadfast reliable operation, protecting your valuable investment.
Operating Environment:
- Ambient Temperature: Expertly designed to operate efficiently within a maximum of +40°C and a minimum of -15°C.
- Altitude: Meticulously engineered to function optimally at altitudes not surpassing 1000m for superior performance.
- Humidity:
- Daily average relative humidity: a robust ≤95%
- Monthly average relative humidity: a resilient ≤90%
- Seismic Intensity: Expertly crafted to endure seismic forces up to an impressive 8 degrees, ensuring steadfast stability and unparalleled safety.
- Installation Conditions: The installation site must be devoid of fire hazards, potential explosions, intense vibrations, chemical exposure, and heavy pollution to guarantee optimal performance.
