Company Profile
Product Description
CHBEB's remarkable single-phase pole-mounted transformers, meticulously designed and crafted by Daelim, are pivotal in transforming utility distribution voltages ranging from 2400V to 34,500V into lower, more practical utilization voltages. These transformers are versatile, efficiently reducing commercial and industrial voltages to 277V, 240/480V, 2400V, and 4800V. Predominantly, they are ideal for stepping down to a single-phase voltage of 120/240V. Furthermore, they are utilized in small substations, for various applications, and can seamlessly step up voltages when required.
CHBEB proudly offers two innovative types of single-phase pole-mounted transformers: the conventional type and the advanced Completely Self-Protected (CSP) type, with impressive power ratings reaching up to 167kVA.
Key Features:
- High Efficiency: These high-performing transformers meet and surpass DOE Energy Efficiency Standards, as well as ANSI/IEEE and CSA standards, promising unparalleled efficiency.
- Standard Features: Equipped with an ISO 9001 quality certification, these transformers feature convenient lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, reliable low-voltage bushings with eyebolt terminals, and essential low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP units deliver enhanced protection through primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, ensuring comprehensive security.
- Durability and Safety: Featuring an innovative self-venting and resealing cover assembly, these transformers guarantee enduring safe and reliable operation.
Operating Environment:
- Ambient Temperature: Operates optimally between a maximum of +40°C and a minimum of -15°C.
- Altitude: Functional up to an altitude not exceeding 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Built to withstand seismic intensities up to 8 degrees, ensuring resilience and reliability.
- Installation Conditions: Ideal installation environment should be clear of fire, explosion hazards, severe vibrations, chemical corrosion, and heavy pollution for optimal performance.
