Product Description
Crafted with precision by Daelim, CHBEB's single-phase pole-mounted transformers are your premier choice for stepping down utility distribution voltages from an impressive range of 2400V to 34,500V to user-friendly levels. Whether intended for commercial use at 277V, 240/480V, or industrial applications like 2400V and 4800V, most of our transformers are optimized for single-phase voltages of 120/240V. Versatility is key, as these transformers excel in small substations and can even step up voltages when needed, all with unmatched reliability and performance.
At CHBEB, we offer a comprehensive two-type range of single-phase pole-mounted transformers: the robust conventional type and the advanced Completely Self-Protected (CSP) type. These transformative powerhouses are rated up to 167kVA, ensuring you have the power you need whenever and wherever you need it.
Key Features:
- High Efficiency: Engineered to meet DOE Energy Efficiency Standards, our transformers not only comply but also surpass ANSI/IEEE and CSA benchmarks, ensuring superior performance and sustainability.
- Standard Features: Our transformers come equipped with ISO 9001 quality certification. They feature lifting lugs, arrester mounting pads, high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings with matching terminals, and secure low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: Packed with enhanced protective features, our CSP units boast primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and convenient overload signal lights, all to safeguard your investment.
- Durability and Safety: Built with a self-venting and resealing cover assembly, our transformers promise enduring safety and reliable operation, protecting your power network for years to come.
Operating Environment:
- Ambient Temperature: Operating efficiently at a maximum of +40°C and a minimum of -15°C.
- Altitude: Designed for altitudes not exceeding 1000m, ensuring performance across varied terrains.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Expertly built to withstand seismic activities of up to 8 degrees, offering resilience in challenging environments.
- Installation Conditions: Ensure an installation environment free from fire hazards, explosions, severe vibrations, chemical corrosion, and heavy pollution for optimal performance.
