Company Profile
Product Description
CHBEB's expertly engineered single-phase pole-mounted transformers, crafted by Daelim, are meticulously designed to efficiently convert utility distribution voltages ranging from 2400V to a staggering 34,500V, down to lower, more manageable utilization voltages. Whether it's stepping down to commercial and industrial standards like 277V, 240/480V, 2400V, or 4800V, or most commonly to a single-phase voltage of 120/240V, these transformers are versatile powerhouses. They find their place in small substations, support miscellaneous applications, and even step up voltages when required.
CHBEB presents two innovative types of single-phase pole-mounted transformers: the traditional and the advanced Completely Self-Protected (CSP) models. These transformers boast an impressive power rating reaching up to 167kVA, underscoring their capacity and reliability.
Key Features:
- High Efficiency: Our transformers not only meet but surpass DOE Energy Efficiency Standards, also exceeding ANSI/IEEE and CSA standards, ensuring optimal performance and energy savings.
- Standard Features: Equipped with ISO 9001 quality certification for assured quality, these units include lifting lugs, arrester mounting pads, high-grade high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and secure low-voltage neutral grounding straps for reliable performance.
- Self-Protected (CSP) Design: CSP units are fortified with primary protective links, surge arresters, secondary circuit breakers, and innovative features such as emergency overload reset handles and overload signal lights, for enhanced protection and convenience.
- Durability and Safety: A self-venting and resealing cover assembly highlights our commitment to safety, promising enduring performance and reliability under various conditions.
Operating Environment:
- Ambient Temperature: With a robust design, these transformers operate efficiently in temperatures ranging from a maximum of +40°C to a minimum of -15°C.
- Altitude: Engineered to function seamlessly at altitudes not exceeding 1000m, delivering consistent performance.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Designed with resilience in mind, they are capable of withstanding seismic intensities up to 8 degrees.
- Installation Conditions: Ideal for environments devoid of fire, explosion risks, severe vibrations, chemical corrosion, and heavy pollution, ensuring safe installation and operation.
