Company Profile
Product Description
CHBEB's expertly crafted single-phase pole-mounted transformers, developed by Daelim, are engineered to seamlessly step down utility distribution voltages, which can span from 2400V to 34,500V, to more accessible utilization voltages. Often used to convert to commercial and industrial voltages such as 277V, 240/480V, 2400V, and 4800V, their primary application is to reduce to a single-phase voltage of 120/240V—ideal for powering essential operations. These transformers also find their purpose in compact substations and serve versatile applications, including stepping up voltages when the demand arises.
CHBEB offers a diverse selection of single-phase pole-mounted transformers: the traditional conventional type and the advanced Completely Self-Protected (CSP) type, both available with power ratings soaring up to 167kVA.
Key Features:
- High Efficiency: Proudly surpassing the stringent DOE Energy Efficiency Standards, these transformers also excel beyond the established ANSI/IEEE and CSA benchmarks.
- Standard Features: Each transformer comes with ISO 9001 quality certification, robust lifting lugs, arrester mounting pads, resilient high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings with eyebolt terminals, and secure low-voltage neutral grounding straps, ensuring impeccable performance.
- Self-Protected (CSP) Design: CSP units are equipped with cutting-edge protection features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, promising unmatched operational safety.
- Durability and Safety: Designed with a sophisticated self-venting and resealing cover assembly, these transformers promise enduring safety and reliability throughout their operational life.
Operating Environment:
- Ambient Temperature: Capable of thriving in environments with temperatures as high as +40°C and as low as -15°C.
- Altitude: Intended for altitudes not exceeding 1000 meters, making them versatile for various terrains.
- Humidity:
- Designed to withstand a daily average relative humidity of ≤95%
- and a monthly average relative humidity of ≤90%, ensuring optimal performance even in humid conditions.
- Seismic Intensity: Built to endure seismic intensities up to 8 degrees, providing resilience and peace of mind.
- Installation Conditions: The ideal installation environment is devoid of fire hazards, explosive materials, severe vibrations, chemical corrosion, and heavy pollution, ensuring safe and efficient operation.
