Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously crafted by Daelim, are an epitome of engineering excellence, specifically designed to adeptly reduce utility distribution voltages that span from 2400V to a towering 34,500V, down to more manageable, lower utilization voltages. These transformers demonstrate their versatility by stepping down voltages for an array of applications, including commercial and industrial sectors with voltages like 277V, 240/480V, 2400V, and 4800V. Predominantly, they serve to transform into a single-phase voltage of 120/240V, effortlessly bridging the voltage gap for small substations and miscellaneous applications, while possessing the capability to elevate voltages as the need arises.
CHBEB is at the forefront of innovation, offering two distinct types of single-phase pole-mounted transformers: the conventional type and the revolutionary Completely Self-Protected (CSP) type. These robust transformers boast power ratings reaching up to a formidable 167kVA, ensuring they meet diverse power requirements with exceptional reliability.
Key Features:
- High Efficiency: Our transformers not only meet but surpass DOE Energy Efficiency Standards, elegantly surpassing the stringent ANSI/IEEE and CSA standards, positioning them as leaders in energy efficiency.
- Standard Features: Every transformer is a testament to quality, featuring ISO 9001 certification, robust lifting lugs, arrester mounting pads, high-voltage porcelain bushings with secure eyebolt terminals, low-voltage bushings with eyebolt terminals, and low-voltage neutral grounding straps for uncompromised performance.
- Self-Protected (CSP) Design: The CSP units are paragons of protection, incorporating primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights, embodying a holistic protective solution.
- Durability and Safety: Boasting a self-venting and resealing cover assembly, these transformers are engineered to provide unwavering safety and reliability over their lifespan.
Operating Environment:
- Ambient Temperature: Perfectly engineered to operate within a temperature range of maximum +40°C to a minimum of -15°C, ensuring adaptability to varied climatic conditions.
- Altitude: Optimized for performance at altitudes not exceeding 1000 meters, these transformers are designed for diverse geographic locales.
- Humidity:
- Daily average relative humidity is maintained at ≤95%, while the monthly average is confined to ≤90%, ensuring consistent performance regardless of humidity fluctuations.
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Crafted to endure seismic intensity of up to 8 degrees, these transformers are a testament to resilience and structural integrity.
- Installation Conditions: Installation should be in environments devoid of fire, explosion risks, severe vibrations, chemical corrosion, and heavy pollution, safeguarding optimal operation.
