Recently, Jiangsu Okay Electric Co., Ltd. successfully designed, manufactured, and delivered the key power transmission system for the Hangzhou Wanxiang Innovation City project – the non-segregated phase bus duct BGFM-20/4000-Z. The success of this major project not only signifies that Jiangsu Okay's technical prowess in the field of high-capacity, long-distance bus ducts has reached industry-leading levels but also means its product will become a vital force powering the heart of this "most advanced smart city."

Wanxiang Innovation City, located in Hangzhou, China, aims to become a new global benchmark for social, economic, and environmental prosperity. Its core launch area – Zone 1 – is Wanxiang Group's new massive lithium battery manufacturing campus. This approximately 440 million square foot "factory of the future" is not only a catalyst for urban development but is itself a grand piece of installation art integrating cutting-edge green technology and human-centric design.
The BGFM-20/4000-Z bus duct supplied by Jiangsu Okay Electric precisely constructs a reliable "main energy artery" for the stable operation of this super factory. With a rated voltage of 20kV and a high rated current of 4000A, this product perfectly meets the stringent requirements of modern lithium battery production lines for extremely high reliability and stability in power supply, thanks to its exceptional

current-carrying capacity, strong short-circuit withstand strength, and low impedance value. To address the challenge of ultra-long-distance power transmission, Jiangsu Okay employed high-conductivity premium T2 copper conductors, unique insulation and sealing technologies, and a high-strength aluminum alloy fully enclosed housing with a protection rating of at least IP54, ensuring long-term, maintenance-free operation in complex industrial environments.
The design philosophy of Zone 1 in Wanxiang Innovation City aligns perfectly with Jiangsu Okay's pursuit of product excellence. The campus is designed as an efficient "laboratory-factory," where each module is meticulously configured to adapt to the local climate, maximizing the use of natural light and ventilation. All workspaces are within 40 feet of walls, minimizing the need for artificial lighting while ensuring every employee enjoys garden views.
This philosophy of deep integration with nature is also reflected in the details of Jiangsu Okay's product. The comprehensive grounding and shielding design within the bus duct system minimizes electromagnetic interference, harmoniously integrating into the overall environment, much like the landscaped buffers surrounding the campus. Addressing the challenge of thermal expansion and contraction in the ultra-long bus duct, the engineering team's innovative flexible compensation and sliding support structures subtly echo the building's smart use of a "gradient method" in planning to reduce energy consumption in layers – whether through the building's peripheral overhangs for shading, facades angled to deflect solar heat gain, or the bus duct's precise compliance with physical principles, all exemplify a unified approach prioritizing passive techniques for achieving efficiency and comfort.
The grand vision for Wanxiang Innovation City extends even further. Its architectural form promotes passive airflow, with circular structures reducing air stagnation and eddies; building-integrated photovoltaics and rooftop PV arrays are extensively applied, aiming for the "net-zero emissions" target for individual factory buildings. All these forward-looking green energy strategies place unprecedented demands on the compatibility, stability, and efficiency of power infrastructure.
The success of Jiangsu Okay Electric in this project is a powerful response to the needs of such world-class projects. From precise technical coordination and lean manufacturing to professional installation guidance, the company's full-process solution ensured this "power artery" seamlessly integrated with the campus's smart and green DNA. It not only provides robust power for Wanxiang Group's lithium battery manufacturing but also lays a solid foundation for the entire Innovation City to realize its environmental vision through its exceptional performance and reliability.
This collaboration marks a milestone for Jiangsu Okay Electric as it advances into the high-end market and participates in shaping global models for future cities. Looking ahead, Jiangsu Okay will continue to uphold its philosophy of "Innovation Leads, Quality is the Foundation," constantly breaking through key technologies. It will contribute "Okay Power" to global green, low-carbon development and a better future for humanity by providing more safe, efficient, and intelligent electrical connection solutions.
