Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously engineered by Daelim, are essential components for efficiently stepping down utility distribution voltages from a robust range of 2400V to 34,500V into more manageable utilization voltages. While a select few are specially designed for commercial and industrial voltages, including 277V, 240/480V, 2400V, and 4800V, the majority excel in transforming voltages to a single-phase 120/240V standard. These versatile transformers play a pivotal role in small substations, diverse applications, and even in voltage step-up scenarios, ensuring a seamless and reliable energy distribution.
CHBEB proudly introduces two distinctive types of single-phase pole-mounted transformers: the time-tested conventional model and the pioneering Completely Self-Protected (CSP) version, each with power ratings reaching up to an impressive 167kVA. These transformers are the embodiment of reliability and efficiency, setting a benchmark in power distribution solutions.
Key Features:
- High Efficiency: These transformers meet DOE Energy Efficiency Standards and go beyond ANSI/IEEE and CSA benchmarks, establishing a new echelon of performance.
- Standard Features: Equipped with ISO 9001 quality certification, these transformers ensure supreme manufacturing standards. They include lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and vital low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are fortified with an extensive array of protective features, such as primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and insightful overload signal lights, all meticulously designed to safeguard the transformer.
- Durability and Safety: Outfitted with an innovative self-venting and resealing cover assembly, this feature ensures the transformer's durability and unwavering reliable operation, thereby protecting your investment.
Operating Environment:
- Ambient Temperature: Efficiently designed to operate between a maximum of +40°C and a minimum of -15°C.
- Altitude: Strategically engineered to function optimally at altitudes not exceeding 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Constructed to endure seismic forces of up to 8 degrees, ensuring its stability and safety.
- Installation Conditions: The installation site should remain free from fire hazards, potential explosions, severe vibrations, chemical exposure, and heavy pollution for optimal transformer performance.
