On July 28, 2026, the power distribution renovation project for the
charging station of Chongqing Yintianhong Technology Co., Ltd., undertaken by Chongqing Sennan Electric Co., Ltd. (hereinafter referred to as "Sennan Electric," international brand "Sennan"), completed all commissioning work and successfully passed the power-on acceptance, officially meeting the conditions for operation. This power distribution renovation project has built a stable and reliable high-voltage power distribution system for the charging station, consolidating the foundation of power infrastructure for the new energy charging business and injecting momentum into the supporting development of green travel in the region.
Against the backdrop of the booming development of the new energy industry, charging stations, as key infrastructure in the new energy vehicle industry chain, place more stringent requirements on the safety level, operational stability, and ease of maintenance of the power supply system. The original power distribution facilities are no longer able to meet the load demands of the high-power charging equipment at the charging station, and there are problems such as limited expansion space and outdated power distribution architecture. To overcome power bottlenecks, Yintianhong Technology launched a power distribution upgrade and renovation project for its charging stations. Leveraging a new high-voltage ring network power distribution system, the project expands power supply capacity and optimizes the distribution architecture, reserving ample space for future expansion of charging facilities and long-term stable operation.
After the project commenced, Sennan Electric quickly assembled a dedicated technical service team to be stationed on-site, coordinating and advancing various tasks such as equipment installation, wiring and commissioning, and system testing. Due to multiple constraints including site layout and construction schedule, the overall operating conditions were complex. The team developed a detailed construction plan tailored to local conditions, scientifically arranging the HXGN-12 series high-voltage switchgear and systematically carrying out cable tray laying, cabinet placement, and line connection. Staff worked during the day to advance hardware installation and basic testing, and seized the window of opportunity at night to conduct joint system commissioning, steadily advancing the project in stages to ensure its timely completion.
High-voltage power distribution engineering is crucial to electrical safety; no detail can be overlooked. Entering the commissioning and acceptance phase, Sennan Electric's technical personnel strictly adhered to power industry standards, using professional testing instruments to verify cabinet parameters, conduct circuit performance tests, and insulation performance checks on each unit. They meticulously inspected line connections, instrument conditions, and the operational logic of protection devices.
Addressing the technical requests raised by various parties on-site, the team thoroughly discussed with the client and power maintenance personnel, continuously optimizing the power distribution operation plan, promptly eliminating various potential operational risks, and ensuring the safe and efficient operation of the entire power distribution system. From equipment arrival, on-site installation, component commissioning, to overall power-on acceptance, standardized quality control was implemented throughout the project lifecycle, safeguarding the bottom line of power safety with meticulous technical services.
With over a decade of experience in the R&D, manufacturing, and engineering support services of high and low voltage complete sets of power distribution equipment, Sennan Electric leverages its technological accumulation to provide integrated power distribution solutions for industrial plants, new energy power stations, commercial buildings, and municipal engineering projects. The company integrates complete equipment manufacturing and on-site engineering implementation capabilities, enabling it to customize power distribution solutions based on the characteristics of different power load scenarios, balancing product quality, construction efficiency, and ease of subsequent operation and maintenance. Addressing the characteristics of new energy charging stations—high load fluctuations and stringent continuous operation requirements—Sennan Electric leveraged extensive project experience to optimize the power distribution system configuration, better matching the unique power consumption conditions of new energy charging infrastructure.
The successful power-on acceptance of the project signifies the successful completion of Sennan Electric's charging station upgrade project. Sennan Electric stated that new energy infrastructure construction is a crucial driver of green and low-carbon development, and the company feels a strong sense of responsibility for participating in the power distribution upgrade of charging stations. The successful delivery of this project is not only a testament to the customer's recognition of Sennan Electric's technical strength and on-site service capabilities but also an important step in the company's continued commitment to the new energy power supply sector.
Looking to the future, Sennan Electric will continue to focus on technological innovation in high and low voltage power distribution, iteratively upgrading its complete power distribution products and continuously improving its full-chain project service capabilities. The company will continue to provide stable and reliable power distribution solutions for markets such as new energy charging stations, industrial parks, and commercial complexes, adhering to a development philosophy prioritizing safety and quality, and working with more partners to support regional new energy infrastructure construction and contribute to the high-quality development of local green energy industries.
