Company Profile
Product Description
CHBEB's exceptional single-phase pole-mounted transformers, masterfully crafted by Daelim, are engineered to transform utility distribution voltages from a high range of 2400V to 34,500V into lower, manageable voltages. These remarkable transformers are adept at converting voltages for commercial and industrial purposes to 277V, 240/480V, 2400V, and 4800V, while primarily focusing on single-phase voltage of 120/240V. Their versatility extends to small substations, miscellaneous applications, and even stepping up voltages when required.
CHBEB is proud to offer two superior types of single-phase pole-mounted transformers: the traditional conventional type and the innovative Completely Self-Protected (CSP) type. These transformers boast impressive power ratings reaching up to 167kVA.
Key Features:
- High Efficiency: Our transformers meet and surpass DOE Energy Efficiency Standards and exceed the stringent ANSI/IEEE and CSA standards, epitomizing energy efficiency.
- Standard Features: Adorned with ISO 9001 quality certification, each transformer is equipped with lifting lugs, arrester mounting pads, high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings with eyebolt terminals, and secure low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: CSP units are enhanced with advanced protection features like primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, ensuring peak performance and safety.
- Durability and Safety: Engineered with a self-venting and resealing cover assembly, these transformers guarantee long-lasting safety and reliable operation.
Operating Environment:
- Ambient Temperature: Capable of enduring temperatures up to a maximum of +40°C and a minimum of -15°C.
- Altitude: Functional at altitudes not exceeding 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Expertly crafted to withstand powerful seismic intensities up to 8 degrees, ensuring durability under extreme conditions.
- Installation Conditions: Ideal installation environments are devoid of fire hazards, explosions, severe vibrations, chemical corrosion, and heavy pollution, ensuring optimal performance.
