Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers are masterfully engineered by Daelim to be essential components in the transformation of utility distribution voltage levels from 2400V to an impressive 34,500V down to easily manageable utilization voltages. While a select few cater to commercial and industrial voltage requirements like 277V, 240/480V, 2400V, and 4800V, the majority are meticulously designed to convert voltages to the universally used single-phase 120/240V. These adaptable transformers are invaluable in small substations, numerous applications, and even voltage step-up settings, ensuring the smooth and efficient distribution of energy.
CHBEB takes great pride in offering two unique types of single-phase pole-mounted transformers: the classic conventional model and the cutting-edge Completely Self-Protected (CSP) variant, both offering power ratings of up to 167kVA. These transformers set the benchmark for reliability and performance.
Key Features:
- High Efficiency: Complies with DOE Energy Efficiency Standards and exceeds ANSI/IEEE and CSA benchmarks, heralding a new era of performance excellence.
- Standard Features: Furnished with ISO 9001 quality certification, reflecting the pinnacle of manufacturing excellence. 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: The CSP models are equipped with a suite of protective measures, such as primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and intuitive overload signal lights, all aimed to protect the transformer.
- Durability and Safety: Featuring an advanced self-venting and resealing cover assembly, this feature ensures the transformer's long-term durability and consistent, reliable operation, safeguarding your valuable investment.
Operating Environment:
- Ambient Temperature: Engineered to perform efficiently in a temperature range from a maximum of +40°C to a minimum of -15°C.
- Altitude: Designed for optimal operation at altitudes up to 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Built to endure seismic forces up to 8 degrees, ensuring steadfast stability and safety.
- Installation Conditions: The installation location must be devoid of fire hazards, potential explosions, intense vibrations, chemical exposure, and severe pollution to maintain optimal performance.
