Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, masterfully designed by Daelim, are crucial for converting utility distribution voltages between 2400V and 34,500V to more user-friendly utilization voltages. While some units cater to specific commercial and industrial voltages such as 277V, 240/480V, 2400V, and 4800V, most transformers are dedicated to converting voltages to a single-phase 120/240V. These adaptable transformers play a pivotal role in small substations, a variety of applications, and even in voltage step-up scenarios, ensuring uninterrupted energy distribution.
CHBEB takes pride in presenting two unique types of single-phase pole-mounted transformers: the traditional model and the revolutionary Completely Self-Protected (CSP) version, with power capacities up to 167kVA. These transformers stand as paragons of reliability and efficiency.
Key Features:
- High Efficiency: Conforms to DOE Energy Efficiency Standards and exceeds ANSI/IEEE and CSA criteria, setting an elevated benchmark for performance.
- Standard Features: Fully equipped with ISO 9001 quality certification, ensuring top-tier 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.
- Self-Protected (CSP) Design: The CSP models are fortified with a suite of protective features, encompassing primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and informative overload signal lights, all engineered to protect the transformer.
- Durability and Safety: Outfitted with an innovative self-venting and resealing cover assembly, this attribute ensures the transformer's durability and consistent reliable operation, safeguarding your investment.
Operating Environment:
- Ambient Temperature: Designed to perform efficiently within a range of maximum +40°C to minimum -15°C.
- Altitude: Expertly crafted to operate optimally at elevations not surpassing 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Ingeniously designed to endure seismic forces up to 8 degrees, guaranteeing stability and security.
- Installation Conditions: The installation area should be devoid of fire risks, potential explosions, severe vibrations, chemical exposure, and heavy pollution to ensure optimal performance.
