Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously engineered by the renowned Daelim, are essential for reducing utility distribution voltages from a wide range of 2400V to 34,500V down to more practical and user-friendly utilization voltages. While some are specifically designed for commercial and industrial settings, accommodating voltages such as 277V, 240/480V, 2400V, and 4800V, the bulk of these transformers are committed to converting voltages into a single-phase 120/240V. These highly adaptable transformers are crucial in small substations and a variety of applications, including voltage step-up scenarios, ensuring seamless and efficient energy distribution.
CHBEB is proud to offer a pair of distinctive single-phase pole-mounted transformers: the traditional model and the cutting-edge Completely Self-Protected (CSP) version, featuring power ratings that reach up to 167kVA. These transformers exemplify reliability and energy efficiency, setting the standard for modern energy solutions.
Key Features:
- High Efficiency: Fully compliant with DOE Energy Efficiency Standards and exceeding the benchmarks set by ANSI/IEEE and CSA, these transformers redefine performance excellence.
- Standard Features: This offering includes ISO 9001 quality certification, ensuring unsurpassed manufacturing excellence. Features encompass lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and crucial low-voltage neutral grounding straps, guaranteeing top-tier functionality.
- Self-Protected (CSP) Design: The CSP models are fortified with an impressive suite of protective elements, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all meticulously designed to protect the transformer and ensure its prolonged service life.
- Durability and Safety: Featuring an innovative self-venting and resealing cover assembly, this sophisticated design ensures the transformer’s durability and unwavering reliable operation, securing your investment in the long run.
Operating Environment:
- Ambient Temperature: Skillfully designed to operate with maximum efficiency between temperatures of +40°C and -15°C.
