Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, masterfully designed by the esteemed Daelim, serve as a critical component for converting utility distribution voltages ranging from a robust 2400V to 34,500V down to more practical utilization voltages. While certain models are precisely engineered for commercial and industrial voltages such as 277V, 240/480V, 2400V, and 4800V, most units are dedicated to transforming power to a single-phase 120/240V. These adaptable transformers are pivotal in small substations, varied applications, and voltage step-up scenarios, facilitating uninterrupted energy distribution with finesse.
CHBEB takes pride in presenting two distinct varieties of single-phase pole-mounted transformers: the traditional model and the groundbreaking Completely Self-Protected (CSP) version, each offering power ratings up to an impressive 167kVA. These transformers stand as a testament to unrivaled reliability and optimal efficiency.
Key Features:
- High Efficiency: Meticulously meets DOE Energy Efficiency Standards and exceeds ANSI/IEEE and CSA criteria, establishing a superior standard for excellence in performance.
- Standard Features: Equipped with ISO 9001 quality certification, underscoring commitment to supreme manufacturing standards. Features include lifting lugs, arrester mounting pads, resilient high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and indispensable low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are fortified with a spectrum of protective elements, encompassing primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, meticulously designed to safeguard the transformer.
- Durability and Safety: Outfitted with a pioneering self-venting and resealing cover assembly, this feature assures the transformer's longevity and consistently dependable operation, securing your investment.
Operating Environment:
- Ambient Temperature: Expertly engineered to perform efficiently between a peak of +40°C and a minimum of -15°C.
- Altitude: Crafted to operate flawlessly at altitudes up to 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Constructed to endure seismic forces up to 8 degrees, ensuring robustness and security.
- Installation Conditions: The installation site should remain free from fire risks, potential explosions, significant vibrations, chemical exposure, and substantial pollution to achieve peak performance.
