Company Profile
Product Description
CHBEB's pioneering single-phase pole-mounted transformers, crafted with precision by Daelim, are engineered for optimal performance in stepping down utility distribution voltages, ranging from an impressive 2400V to 34,500V, to more manageable lower utilization voltages. Whether it's stepping down to commercial and industrial voltages like 277V, 240/480V, 2400V, and 4800V, or predominantly to a single-phase voltage of 120/240V, these transformers excel. Their versatility extends to applications in small substations and various other needs, and they are equally adept at stepping up voltages when the situation demands.
CHBEB sets the standard with two distinct types of single-phase pole-mounted transformers: the conventional type and the innovative Completely Self-Protected (CSP) type. These robust transformers boast power ratings reaching up to an impressive 167kVA, ensuring a solution for a wide array of energy distribution requirements.
Key Features:
- High Efficiency: These transformers are meticulously designed to meet DOE Energy Efficiency Standards, exceeding even the rigorous benchmarks set by ANSI/IEEE and CSA standards, ensuring exceptional performance and energy savings.
- Standard Features: Each transformer comes equipped with ISO 9001 quality certification, ensuring the utmost in reliability and performance. They feature lifting lugs, arrester mounting pads, high-voltage porcelain bushings with secure eyebolt terminals, low-voltage bushings with eyebolt terminals, and low-voltage neutral grounding straps for comprehensive protection and ease of maintenance.
- Self-Protected (CSP) Design: The CSP units are fortified with enhanced protection features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, delivering unparalleled safety and responsiveness in demanding conditions.
- Durability and Safety: Engineered for longevity and security, these transformers feature a self-venting and resealing cover assembly, guaranteeing years of safe and reliable service, even under the most challenging operational environments.
Operating Environment:
- Ambient Temperature: Capable of operating in temperatures ranging from a maximum of +40°C to a minimum of -15°C, ensuring exceptional performance in diverse climates.
- Altitude: Efficiently designed to function at altitudes not exceeding 1000m, maintaining performance integrity at higher elevations.
- Humidity:
- Daily average relative humidity: maintained at ≤95%
- Monthly average relative humidity: capped at ≤90%
- Seismic Intensity: Expertly crafted to withstand seismic intensities of up to 8 degrees, ensuring resilience against natural forces.
- Installation Conditions: For optimal performance and longevity, the installation environment should be free from fire risks, explosion hazards, severe vibrations, chemical corrosion, and heavy pollution, ensuring a safe and stable operational space.
