Product Description
CHBEB's single-phase pole-mounted transformers, crafted with precision by Daelim, are quintessential for stepping down utility distribution voltages from a staggering range of 2400V to 34,500V to more practical, lower utilization voltages. While adept at reducing commercial and industrial voltages to levels such as 277V, 240/480V, 2400V, and 4800V, they predominantly serve to convert to a single-phase voltage of 120/240V. Additionally, these versatile transformers find their purpose in compact substations and various niche applications, with the capability to step up voltages when required.
CHBEB offers two exemplary models of single-phase pole-mounted transformers: the trusted conventional type and the innovative Completely Self-Protected (CSP) type. Both variants exhibit remarkable power ratings, reaching up to 167kVA.
Key Features:
- High Efficiency: Unwavering compliance with DOE Energy Efficiency Standards, while surpassing the benchmarks set by ANSI/IEEE and CSA standards.
- Standard Features: Comprises of ISO 9001 quality certification, robust lifting lugs, arrester mounting pads, high-voltage porcelain bushings with secure eyebolt terminals, low-voltage bushings with eyebolt terminals, and resilient low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are fortified with superior protection features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and vital overload signal lights.
- Durability and Safety: Engineered with a self-venting and resealing cover assembly, ensuring unwavering safety and reliable operation over the long term.
Operating Environment:
- Ambient Temperature: Ranging from a maximum of +40°C to a minimum of -15°C.
- Altitude: Capable of operating at altitudes up to 1000m.
- Humidity:
- Daily average relative humidity: not surpassing 95%
- Monthly average relative humidity: not exceeding 90%
- Seismic Intensity: Constructed to endure seismic intensities up to 8 degrees.
- Installation Conditions: The installation setting must be devoid of fire hazards, explosions, severe vibrations, chemical corrosion, and heavy pollutants.
