Company Profile
Product Description
CHBEB's single-phase pole-mounted transformers, meticulously designed and crafted by Daelim, serve a pivotal role in efficiently reducing utility distribution voltages that span from 2400V to a robust 34,500V down to more manageable utilization voltages. While they are adept at stepping down to commercial and industrial voltages including 277V, 240/480V, 2400V, and 4800V, their primary application is in converting power to a single-phase voltage of 120/240V. These versatile transformers also find applications in small substations and various other scenarios, adeptly stepping up voltages when the situation demands.
CHBEB takes pride in fabricating two distinct types of single-phase pole-mounted transformers: the time-tested conventional type and the advanced Completely Self-Protected (CSP) type. Both varieties boast impressive power ratings that stretch up to a generous 167kVA.
Key Features:
- High Efficiency: These transformers not only meet but surpass DOE Energy Efficiency Standards, along with ANSI/IEEE and CSA benchmarks, ensuring unparalleled performance.
- Standard Features: Comprehensively equipped with ISO 9001 quality certification, robust lifting lugs, arrester mounting pads, high-voltage porcelain bushings with secure eyebolt terminals, low-voltage bushings, and low-voltage neutral grounding straps, ensuring operational excellence.
- Self-Protected (CSP) Design: CSP units are fortified with enhanced protection features including primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and overload signal lights for superior safeguarding.
- Durability and Safety: Engineered with a self-venting and resealing cover assembly, these transformers promise long-term, reliable, and safe operation.
Operating Environment:
- Ambient Temperature: Designed to operate efficiently with a maximum temperature of +40°C and a minimum of -15°C.
- Altitude: Operational reliability assured at altitudes not exceeding 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Built to endure seismic activities with an intensity of up to 8 degrees, ensuring resilience.
- Installation Conditions: It is imperative for the installation site to be free from fire hazards, explosive materials, severe vibrations, chemical corrosion, and heavy pollution to maintain optimal performance.
