Product Description
Crafted by the esteemed Daelim, CHBEB's single-phase pole-mounted transformers are the epitome of engineering excellence. Designed to efficiently transform utility distribution voltages from a wide range of 2400V to an impressive 34,500V, these transformers ensure seamless voltage reduction to practical utilization levels. Whether stepping down to commercial or industrial voltages like 277V, 240/480V, 2400V, and 4800V, or the frequently demanded single-phase voltage of 120/240V, CHBEB transformers guarantee unmatched performance. Their versatility extends to small substations and diverse applications, with the capability to step up voltages when necessary, ensuring they are indispensable in modern electrical network solutions.
CHBEB proudly offers two distinguished models of single-phase pole-mounted transformers: the traditional conventional type and the sophisticated Completely Self-Protected (CSP) type. Each model boasts power ratings reaching up to an impressive 167kVA, demonstrating CHBEB's commitment to delivering robust and reliable electrical solutions tailored to diverse needs.
Key Features:
- High Efficiency: Our transformers not only meet but surpass the rigorous DOE Energy Efficiency Standards, as well as ANSI/IEEE and CSA standards, ensuring optimal efficiency and performance.
- Standard Features: Each transformer is equipped with ISO 9001 quality certification, ensuring excellence. Additional features include lifting lugs, arrester mounting pads, high-voltage porcelain bushings with secure eyebolt terminals, low-voltage bushings with eyebolt terminals, and dependable low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: CSP units are designed with advanced protection capabilities, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, providing peace of mind and safety.
- Durability and Safety: Engineered with a self-venting and resealing cover assembly, these transformers promise long-term, reliable, and safe operation, securing your investment over time.
Operating Environment:
- Ambient Temperature: Capable of operating in temperatures as high as +40°C and as low as -15°C, maintaining performance across a range of environments.
- Altitude: Designed to function optimally at altitudes not exceeding 1000m, making them versatile for various geographical locations.
- Humidity:
- Designed to operate under a daily average relative humidity of ≤95% and a monthly average of ≤90%, ensuring reliability even in humid conditions.
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Specifically engineered to withstand seismic intensity up to 8 degrees, ensuring resilience and stability in earthquake-prone areas.
- Installation Conditions: To ensure optimal functionality, the installation site should be devoid of fire, explosion risks, severe vibrations, chemical corrosion, and heavy pollution.
