Company Profile
Product Description
Engineered to perfection by Daelim, CHBEB's single-phase pole-mounted transformers are vital in stepping down utility distribution voltages, ranging from 2400V to 34,500V, to user-friendly utilization voltages. While some are custom-designed for commercial and industrial voltages like 277V, 240/480V, 2400V, and 4800V, most are primarily dedicated to transforming voltages to a single-phase 120/240V. These multifunctional transformers are indispensable in small substations and various applications, as well as in voltage step-up scenarios, ensuring flawless energy distribution across networks.
CHBEB takes pride in presenting two distinct variants of single-phase pole-mounted transformers: the traditional model and the pioneering Completely Self-Protected (CSP) version, with power ratings soaring up to 167kVA. These transformers are the epitome of dependability and high efficiency.
Key Features:
- High Efficiency: Not only does it comply with DOE Energy Efficiency Standards, but it also surpasses ANSI/IEEE and CSA benchmarks, establishing a new benchmark for unrivaled performance.
- Standard Features: It includes ISO 9001 quality certification, guaranteeing premium manufacturing standards. Features such as lifting lugs, arrester mounting pads, resilient high-voltage porcelain bushings with eyebolt terminals, low-voltage bushings, and crucial low-voltage neutral grounding straps are all standard.
- Self-Protected (CSP) Design: CSP models are fortified with a suite of protective features like primary protective links, surge arresters, secondary circuit breakers, emergency overload reset handles, and clear overload signal lights, all meticulously crafted to protect the transformer.
- Durability and Safety: With its cutting-edge self-venting and resealing cover assembly, this feature ensures enduring longevity and steadfast reliable operation, providing robust protection for your investment.
Operating Environment:
- Ambient Temperature: Designed to function at peak efficiency between maximum +40°C and minimum -15°C.
- Altitude: Specifically engineered for optimal performance at altitudes not exceeding 1000m.
- Humidity:
- Daily average relative humidity: ≤95%
- Monthly average relative humidity: ≤90%
- Seismic Intensity: Built to withstand seismic forces up to 8 degrees, ensuring unyielding stability and safety.
- Installation Conditions: The installation site must be free of fire hazards, potential explosions, severe vibrations, chemical exposure, and heavy pollution to guarantee ultimate performance.
