Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, crafted with precision by Daelim, are quintessential in converting utility distribution voltages from a vast range of 2400V to 34,500V down to lower, more functional utilization voltages. While they adeptly handle commercial and industrial voltages like 277V, 240/480V, 2400V, and 4800V, their primary use is to transform to a singular 120/240V phase. These versatile transformers are indispensable in small substations and various applications, providing the flexibility to step up voltages when required.
CHBEB expertly manufactures two pivotal types of single-phase pole-mounted transformers: the classic conventional type and the innovative Completely Self-Protected (CSP) type. Each of these robust transformers boasts a power rating capability of up to 167kVA, ensuring they meet a wide array of power distribution requirements.
Key Features:
- High Efficiency: Meticulously engineered to meet DOE Energy Efficiency Standards, these transformers not only fulfill but surpass the stringent ANSI/IEEE and CSA standards, promising outstanding energy performance.
- Standard Features: Each transformer is equipped with ISO 9001 quality certification, ensuring top-notch quality and reliability. Additional features include lifting lugs, arrester mounting pads, high-voltage porcelain bushings with eyebolt terminals, and low-voltage bushings with eyebolt terminals, complemented by low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are fortified with advanced protection features, including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, ensuring unparalleled safety and performance.
- Durability and Safety: Engineered for resilience, these transformers feature a self-venting and resealing cover assembly that guarantees long-term safe and reliable operation.
Operating Environment:
- Ambient Temperature: Optimal operation between a maximum of +40°C and a minimum of -15°C.
- Altitude: Suitable for altitudes not surpassing 1000m, ensuring consistent performance.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Designed with robust engineering to withstand seismic intensities of up to 8 degrees, safeguarding against natural calamities.
- Installation Conditions: The installation site must be devoid of fire hazards, explosion risks, extreme vibration, chemical corrosion, and significant pollution to ensure optimal functionality.
