Company Profile
Product Description
CHBEB, in collaboration with Daelim, presents an innovative range of single-phase pole-mounted transformers that expertly step down utility distribution voltages from a versatile range of 2400V to 34,500V. Primarily serving the needs of commercial and industrial sectors with voltages like 277V, 240/480V, and more, these transformers are predominantly utilized to transform voltages to a practical single-phase voltage of 120/240V. Beyond their primary function, they are indispensable in small substations and various specialized applications, showcasing their flexibility in stepping up voltages as required.
CHBEB takes pride in manufacturing two distinct types of single-phase pole-mounted transformers: the versatile conventional type and the robust Completely Self-Protected (CSP) type. With power ratings soaring up to an impressive 167kVA, these transformers are engineered to meet diverse electrical demands with precision and reliability.
Key Features:
- High Efficiency: These transformers not only meet but surpass DOE Energy Efficiency Standards, as well as ANSI/IEEE and CSA standards, ensuring optimal performance and energy conservation.
- Standard Features: Ensuring top-notch quality, these units boast ISO 9001 certification, equipped with lifting lugs, arrester mounting pads, high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and reliable low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP design is fortified with a suite of protective features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and intuitive overload signal lights, all crafted to safeguard against unexpected electrical challenges.
- Durability and Safety: Enhanced with a self-venting and resealing cover assembly, these transformers are engineered for prolonged safe and reliable operation, ensuring peace of mind with every use.
Operating Environment:
- Ambient Temperature: Effortlessly operates between a maximum of +40°C and a minimum of -15°C, adapting to diverse climatic conditions with ease.
- Altitude: Capable of functioning effectively at altitudes not exceeding 1000 meters, these transformers are versatile in their application.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Expertly designed to withstand seismic intensities up to 8 degrees, ensuring robust performance even in challenging environments.
- Installation Conditions: For optimal performance, the installation environment should be devoid of fire, explosion risks, severe vibrations, chemical corrosion, and heavy pollution.
