mobile substation is an effective emergency power supply equipment. It is a small substation that organically integrates and installs the electrical primary and secondary equipment on one or more semitrailers. It has the characteristics of complete functions, small land occupation, flexibility and wide application scenarios. It can provide temporary, phased or emergency power supply.If the substation is upgraded and put into operation instead of the transformed equipment, the power outage time can be greatly shortened; High load seasons or periods, large-scale temporary activities, large-scale project construction, etc. to alleviate the shortage of power supply in local areas; In case of natural disasters, the substation equipment is seriously damaged, and the mobile substation can replace the whole substation and quickly restore the power supply; Areas beyond the pre power construction planning, such as the phased temporary construction power supply of the new industrial park, shall be put into operation as a temporary substation to alleviate the tension of power supply and avoid the tedious change of planning.
The mobile substation stands out as a highly effective emergency power supply equipment in the electrical engineering field. It integrates electrical primary and secondary equipment—including transformers, switchgear, and control systems—onto one or multiple semitrailers in an organic, compact manner, forming a portable small-scale substation. This integrated design endows it with distinct advantages: complete functions that cover power transformation, distribution, and monitoring, a small land occupation that eliminates the need for large fixed construction areas, and exceptional flexibility that allows for rapid deployment.
Its application scenarios are remarkably wide, serving as a reliable source for temporary, phased, or emergency power supply. When a fixed substation undergoes upgrading or equipment replacement, deploying a mobile substation to take over operations can drastically shorten power outage time, minimizing losses for industrial users and inconvenience for residents. During high-load seasons (such as summer’s peak air-conditioning usage) or large-scale temporary events like sports tournaments and cultural festivals, as well as during large construction projects, it effectively alleviates local power supply shortages. In the aftermath of natural disasters like earthquakes or floods that severely damage fixed substation equipment, the mobile substation can replace the entire damaged substation, enabling quick power restoration to support rescue efforts and daily life. Additionally, in areas beyond pre-planned power infrastructure—such as new industrial parks requiring phased temporary construction power—it operates as a temporary substation, easing power supply tensions without the hassle of revising complex construction plans.
Company Profile
Nanjing Electric was founded in 1936 and is the first high-voltage ceramic manufacturer in the history of China's electrical industry. It is also the headquarters of Baiyun Group in the East China region. Nanjing Electric has been rated as one of the top 500 mechanical industrialization enterprises in China and a first-class industrial enterprise in China. At present, the base covers an area of 19 hectares and employs 1000+ people. The industrial base was put into operation with equipment in 2015. Nanjing Electric specializes in developing glass insulators, composite insulators, and ceramic insulator products. In 1958, China developed the first Tempered Glass insulator and condenser Bushing, filling the domestic gap. The company's products are exported to more than 120 countries and regions around the world, such as the Americas, Australia, the Middle East, Southeast Asia, and more than 50% of countries and regions in Europe. The main customers are national power grid companies or local power grid companies in various countries. The domestic market has achieved full coverage. The company's products are widely used in national strategic projects, including 33 UHV projects above 800KV. Our company is the largest insulator supplier in national engineering.
Nanjing Electric International Co., Ltd., formerly known as the Overseas Business Unit of Nanjing Electric Technology Group, established an international trade company in 2021 based on the development strategy of the group. With insulators and sleeves as the two flagship exhibits, the company actively carries out resource and multi-party cooperation around common values and market views. On the way to the world, international trading companies will firmly step forward and work hard for the century old white clouds and the world's white clouds.
The international trade team participated in international power exhibitions held in countries each year such as Germany, the United States, Brazil, Saudi Arabia, Egypt, India, Italy, Saudi Arabia, Russia, Australia, the Philippines, Thailand, Spain, Mexico, etc; Track the progress of key power projects in various countries; Further promote the internationalization process of products.
Facing the future, the company will focus on the needs of national power construction, seize the opportunities of new power infrastructure, ultra-high voltage projects, the "the Belt and Road" construction, and the development of green energy. According to the strategic positioning of Baiyun Electric Group to build the company into the second headquarters of the group relying on the Yangtze River Delta, the company will build and develop a world-class insulator and related product R&D and production base, explore and build new products, new technologies, and new formats, Make new contributions to national power construction and global power development, and strive to become a century old enterprise.
