Product Description
Experience the unparalleled engineering excellence of CHBEB's single-phase pole-mounted transformers, expertly designed and crafted by Daelim. These transformers excel in reducing utility distribution voltages, ranging from 2400V up to 34,500V, to levels that are easily manageable, ensuring a seamless supply for diverse applications. Industries are empowered with voltages such as 277V, 240/480V, 2400V, and 4800V, while residential areas bask in the comfort of 120/240V. With their versatile functionality, they are perfectly suited for small substations and have the capability to elevate voltages when necessary.
CHBEB is proud to offer two distinguished variants of single-phase pole-mounted transformers: the formidable conventional model and the advanced Completely Self-Protected (CSP) model, with power ratings reaching an impressive 167kVA, catering to a wide range of electrical distribution needs.
Key Features:
- High Efficiency: These transformers are meticulously designed to meet and exceed the DOE Energy Efficiency Standards, and they comply with the stringent ANSI/IEEE and CSA standards, assuring top-tier performance.
- Standard Features: Benefit from ISO 9001 quality assurance with key components such as lifting lugs, arrester mounting pads, high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings with eyebolt terminals, and robust low-voltage neutral grounding straps.
- Self-Protected (CSP) Design: The CSP models are enhanced with primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and signal lights that alert to overloads, ensuring an advanced level of protection.
- Durability and Safety: Featuring an innovative self-venting and resealing cover assembly, these transformers guarantee long-lasting safety and reliability, crucial for sustained operational excellence.
Operating Environment:
- Ambient Temperature: Optimally functions between a temperature range of +40°C maximum and -15°C minimum, maintaining superior performance throughout.
- Altitude: Designed to maintain full functionality at altitudes up to 1000m, these transformers deliver consistent performance even in elevated regions.
- Humidity:
- Daily average relative humidity is maintained at ≤95%, ensuring efficient operation in varying climatic conditions.
- Monthly average relative humidity does not exceed 90%, safeguarding against moisture-related issues.
- Seismic Intensity: Constructed to withstand seismic intensities up to 8 degrees, these transformers ensure robust performance amidst challenging seismic activities.
- Installation Conditions: For optimal operation, the installation environment must be devoid of fire hazards, explosive threats, severe vibrations, chemical corrosion, and heavy pollution.
