Product Description
CHBEB's single-phase pole-mounted transformers, masterfully engineered by Daelim, are essential powerhouses for converting utility distribution voltages ranging from 2400V to 34,500V into more manageable, usable voltages. While a select few are expertly crafted for commercial and industrial voltages such as 277V, 240/480V, 2400V, and 4800V, the majority are devoted to transforming voltages to a single-phase 120/240V. These versatile transformers are crucial in small substations and numerous applications, including voltage step-up scenarios, ensuring seamless and efficient energy distribution across various settings.
CHBEB proudly presents two distinctive types of single-phase pole-mounted transformers: the traditional model and the pioneering Completely Self-Protected (CSP) version, offering power ratings up to an impressive 167kVA. These transformers epitomize the pinnacle of reliability, efficiency, and cutting-edge engineering.
Key Features:
- High Efficiency: Compliant with DOE Energy Efficiency Standards, these transformers exceed ANSI/IEEE and CSA benchmarks, setting a new paradigm for superior performance and energy savings.
- Standard Features: These transformers come equipped with ISO 9001 quality certification, attesting to the highest manufacturing excellence. Features include lifting lugs, arrester mounting pads, robust high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and essential low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are fortified with an array of protective features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and intuitive overload signal lights, all meticulously designed to secure the transformer and ensure uninterrupted performance.
- Durability and Safety: Featuring an advanced self-venting and resealing cover assembly, this innovation guarantees the long-term durability and dependable operation of the transformer, thus safeguarding your important investment and ensuring peace of mind.
Operating Environment:
- Ambient Temperature: Engineered for outstanding performance within a temperature range of maximum +40°C to minimum -15°C, ensuring adaptability to diverse climatic conditions.
- Altitude: Strategically designed to function optimally at altitudes not exceeding 1000m, making it versatile for various geographical locations.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Meticulously crafted to endure seismic forces up to 8 degrees, ensuring stability, safety, and durability even in seismic zones.
- Installation Conditions: For optimal performance, the installation site should be devoid of fire hazards, potential explosions, severe vibrations, chemical exposure, and heavy pollution, ensuring a safe and efficient operational environment.
