Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers are meticulously engineered by Daelim, serving as fundamental components in the reduction of utility distribution voltages, skillfully converting voltages from 2400V to an impressive 34,500V down to user-friendly levels. A few sophisticated models cater specifically to commercial and industrial needs with voltages such as 277V, 240/480V, 2400V, and 4800V. Meanwhile, the majority focus on transforming voltages to a standard single-phase 120/240V. These adaptable transformers are indispensable, proving their worth in small substations, a multitude of applications, and even in voltage elevation scenarios, thereby ensuring flawless and uninterrupted energy distribution.
CHBEB is proud to present two exceptional variants of single-phase pole-mounted transformers: the traditional model and the pioneering Completely Self-Protected (CSP) model, each offering power ratings of up to 167kVA. These transformers stand as paragons of reliability and efficiency, engineered to meet the diverse demands of modern power systems.
Key Features:
- High Efficiency: Exceeds DOE Energy Efficiency Standards and outperforms ANSI/IEEE and CSA criteria, establishing a benchmark in performance excellence.
- Standard Features: Fully equipped with ISO 9001 quality certification, which assures superior manufacturing benchmarks. Features include lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and indispensable low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: CSP models are enhanced with a comprehensive suite of protective features such as primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights—all engineered to preserve the integrity of the transformer.
- Durability and Safety: Featuring an avant-garde self-venting and resealing cover assembly, this innovation ensures the transformer's durability and consistent, reliable operation, thus protecting your valuable investment.
Operating Environment:
- Ambient Temperature: Expertly designed for efficient operation between a maximum of +40°C and a minimum of -15°C.
- Altitude: Carefully constructed to perform optimally at altitudes not surpassing 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Engineered to withstand seismic forces reaching up to 8 degrees, guaranteeing stability and security.
- Installation Conditions: The installation location should be devoid of fire risks, potential explosions, intense vibrations, chemical exposure, and heavy pollution to ensure optimal functionality.
