Product Overview

        • BHPS cast resin dry type transformers are engineered specifically for stable and reliable power distribution in various electrical systems.The product line offers a comprehensive range of voltage configurations and power ratings, which are carefully designed to accommodate the diverse electrical load requirements of different application scenarios.

        • All transformers adhere to well-recognized international industry standards and are currently undergoing UL certification—a globally authoritative safety certification—to verify their compliance with the strict quality and safety benchmarks set by international electrical authorities.

High Reliability and Safety

        • Currently undergoing UL certification, a globally recognized safety certification that ensures the product meets rigorous safety and performance criteria for electrical equipment.

        • Strictly conforms to UL 1562 and IEEE C57.12.01 standards, which are authoritative international standards governing the design, manufacture, and performance of dry type transformers.

Flexible

        • Supports multiple flexible voltage configurations: 13.8kV and 34.5kV for the primary side (input voltage) and 480V and 240V for the secondary side (output voltage), allowin it to adapt to different power supply systems.

        • Covers a wide rated power range from 500kVA to 8000kVA, which can effectively meet the power demand of both small-scale and large-scale electrical systems.

        • Offers two available thermal insulation classes—155(F) and 180(H)—which determine the maximum operating temperature the transformer can withstand and ensure long-term stable operation under different thermal conditions.

        • Provides multiple enclosure protection grades, namely NEMA 1, NEMA 12, and NEMA 3R, each designed to suit different environmental conditions and protect the internal components from external hazards such as dust, moisture, and physical impact.

        • Is suitable for both indoor and outdoor installation environments, thanks to its multiple protection grades, making it adaptable to various working conditions such as indoor workshops and outdoor power stations.

High Efficiency

        • Effectively meets the energy efficiency requirements issued by the U.S. Department of Energy (DOE), which are scheduled to be officially released in 2027. This optimized energy efficiency design helps reduce unnecessary energy loss during power transmission and improve overall energy utilization.
