Product Description
CHBEB's meticulously engineered single-phase pole-mounted transformers are crafted by Daelim to excel in stepping down utility distribution voltages, ranging from 2400V to an impressive 34,500V, to more manageable utilization voltages. While some units serve the purpose of reducing voltages to commercial and industrial levels such as 277V, 240/480V, 2400V, and 4800V, the majority cater to the residential standard of 120/240V. These adaptable transformers also find their place in small substations and are versatile enough to meet various miscellaneous applications, including voltage step-up scenarios when needed.
CHBEB is a leader in manufacturing two sophisticated types of single-phase pole-mounted transformers: the traditional conventional type and the innovative Completely Self-Protected (CSP) type, boasting power ratings that reach up to an impressive 167kVA.
Key Features:
- High Efficiency: Proudly surpasses DOE Energy Efficiency Standards and consistently exceeds the rigorous benchmarks set by ANSI/IEEE and CSA standards.
- Standard Features: Showcasing ISO 9001 quality certification, these transformers are equipped with lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with secure eyebolt terminals, reliable low-voltage bushings with eyebolt terminals, and dependable low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: CSP units are fortified with enhanced protection features, including primary protective links, efficient surge arresters, secondary circuit breakers, emergency overload reset handles, and intuitive overload signal lights.
- Durability and Safety: Designed with a self-venting and resealing cover assembly, this ensures the transformer operates safely and reliably over an extended lifespan.
Operating Environment:
- Ambient Temperature: Capable of withstanding a maximum of +40°C and a minimum of -15°C.
- Altitude: Optimally designed for locations not exceeding an altitude of 1000m.
- Humidity:
- Daily average relative humidity: Maintained at ≤95% for optimal performance.
- Monthly average relative humidity: Kept at ≤90% ensuring durability and efficiency.
- Seismic Intensity: Engineered to withstand seismic activities up to an intensity of 8 degrees, ensuring resilience and stability.
- Installation Conditions: Optimal installation demands an environment free from fire hazards, explosions, severe vibrations, chemical corrosion, and heavy pollution to maintain integrity and performance.
