Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously designed by Daelim, are crucial for efficiently stepping down utility distribution voltages from a range of 2400V to 34,500V to more user-friendly utilization voltages. Although some models are specifically engineered for commercial and industrial voltages such as 277V, 240/480V, 2400V, and 4800V, the bulk of these transformers excel in converting voltages to a single-phase 120/240V. These adaptable transformers are essential in small substations, diverse applications, and even in voltage step-up situations, ensuring smooth and reliable energy distribution that meets various power needs.
CHBEB proudly presents two distinct models of single-phase pole-mounted transformers: the classic conventional version and the pioneering Completely Self-Protected (CSP) model, each offering power ratings up to an impressive 167kVA. These transformers stand as paragons of reliability and operational efficiency, designed to withstand and excel in demanding environments.
Key Features:
- High Efficiency: Exceeds DOE Energy Efficiency Standards and outperforms ANSI/IEEE and CSA criteria, setting an industry benchmark for exceptional performance.
- Standard Features: Fully equipped with ISO 9001 quality certification, assuring adherence to the highest manufacturing standards. Features include lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and crucial low-voltage neutral grounding straps, all engineered for optimal performance and durability.
- Self-Protected (CSP) Design: The CSP models are fortified with a comprehensive suite of protective features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all meticulously designed to ensure the transformer's safety and operational integrity.
- Durability and Safety: Features an advanced self-venting and resealing cover assembly, this innovation ensures the transformer's endurance and consistently reliable performance, safeguarding your valuable investment over the long term.
Operating Environment:
- Ambient Temperature: Capably designed to function efficiently within a temperature range of +40°C maximum to -15°C minimum.
- Altitude: Expertly designed to operate optimally at altitudes up to 1000 meters, ensuring reliable performance.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Expertly crafted to endure seismic forces up to 8 degrees, ensuring unwavering stability and safety in challenging conditions.
- Installation Conditions: Installation sites should be devoid of fire hazards, potential explosion risks, severe vibrations, chemical exposure, and significant pollution for uninterrupted and optimal transformer performance.
