Against the grand backdrop of the "Dual Carbon" strategy and the national initiative to build a strong transportation network, the electrification of heavy-duty trucks has become a pivotal campaign in driving the green transformation of the transportation sector. As a leader in transformer energy-saving technology and a national-level "Manufacturing Single Champion" enterprise, Haihong Electric has consistently focused on reinforcing the "foundation" of power distribution for new energy heavy-duty truck charging and swapping infrastructure, providing robust support for the steady development of the industry.
Nearly 100 Units Deployed in the Field
In 2025, nearly 100 innovative units made by Haihong Electric have been applied in various new energy heavy-duty truck charging and swapping projects across Guangdong and other provinces. Its service network has achieved comprehensive coverage throughout Guangdong and is continually expanding outward.
Repeat Purchases Demonstrate Market Trust
From bustling ports to major logistics hubs, Haihong Electric's self-developed Miniaturized Double-layer Prefabricated Substations and Fully Insulated Open-Type 3D Wound Core Dry-Type Transformers have become the preferred "distribution heart" for numerous heavy-duty truck charging and swapping stations. Thanks to their exceptional real-world performance, these products have earned the sustained trust of clients from various sectors including logistics companies and charging operators, achieving a transition from single-point usage to multi-point repeat purchases. Among them, the Miniaturized Double-layer Double-transformer Substation, which is equivalent to "two units in one," has become the preferred power distribution solution for large-scale heavy-duty truck charging and swapping stations due to its highly efficient and compact design.
Fortifying Safety Baselines, Elevating Efficiency Standards
All operational projects have maintained safe operation to date, with equipment demonstrating consistent stability and reliability under demanding working conditions. Based on customer feedback and on-site data, stations utilizing Haihong's substations have seen significant reductions in electrical energy loss. Moreover, even under continuous high-load operation, the equipment maintains low temperature rise and high efficiency. The products firmly safeguard the lifeline of distribution security with their excellent short-circuit withstand capability and heat dissipation design. Their compact structure and energy-saving technology continue to reduce electricity losses and save operational costs for the stations.
Supporting the Green Arteries of Heavy-Duty Trucks with High Quality
Today, Haihong Electric's products are silently safeguarding the operation of new energy heavy-duty trucks across the land of South Guangdong and broader regions. Every kilowatt-hour of efficiently converted electricity and every reliable, rapid energy top-up collectively and tangibly reduce carbon emissions in the transportation sector, actively contributing to China's green transportation transition.
Looking ahead, Haihong Electric will continue to deepen its involvement in the new energy heavy-duty truck industry. With safer, more energy-efficient, and smarter power distribution solutions, the company will solidify the infrastructure foundation for the development of heavy-duty truck electrification, contributing robust strength from Chinese manufacturing to the construction of a green transportation nation and the advancement of global energy transformation.
