The secondary equipment cabin is highly integrated with the integrated automation system, which has the functions of monitoring, control and telecontrol communication of conventional substation. At the same time, it is equipped with perfect security and video monitoring system, fire alarm system and air conditioning system. It has unattended conditions to realize the installation and connection of panels and cabinets in the factory and transport them to the site in sections or as a whole, Only the cabin needs to be simply spliced on site, which greatly reduces the on-site workload.The overall product has the advantages of safety and reliability, small floor area, short construction cycle, long service life and flexible layout. It can be designed flexibly according to the geographical location and meteorological conditions of the station, and can also be constructed by stages according to the long-term planning of this phase. It can be relocated in different places in a short time. It has a beautiful and diverse appearance, and the color painting and spraying can be integrated with the surrounding environment.
The secondary equipment cabin, a core component of modern power systems, achieves high integration with an integrated automation system. This system fully replicates the monitoring, control, and telecontrol communication functions of conventional substations—enabling real-time data collection on equipment operating parameters (such as voltage, current, and temperature), remote control of switchgear operations, and stable data transmission with upper-level dispatch centers. To ensure all-around safety, the cabin is equipped with a multi-layer protection system: a high-sensitivity security and video monitoring system that covers all key areas to prevent unauthorized access; a fire alarm system with smoke and temperature detectors that triggers automatic alerts and linkage measures in case of fire risks; and a constant-temperature air conditioning system that maintains a stable internal environment (20-25℃), avoiding equipment malfunctions caused by extreme temperatures. These configurations enable the cabin to meet unattended operation standards, significantly reducing manual management costs.
In terms of production and on-site deployment, the cabin adopts a prefabricated model. All internal panels and cabinets—including automation control cabinets, communication cabinets, and protection cabinets—are fully installed, wired, and debugged in the factory to ensure stable performance. During transportation, it can be delivered in sections (for large-capacity models) or as a whole (for compact designs) based on road and transportation conditions. On-site work is simplified to simple cabin splicing and connection to external power and communication lines, which takes only 3-5 days to complete—greatly reducing on-site workload and shortening the construction cycle by 60% compared to traditional on-site assembly.
The product also has outstanding comprehensive advantages: its robust structure and high-quality components ensure safety and reliability, with an average fault-free operation period of over 8,000 hours; its compact design saves more than 50% of the floor area compared to traditional secondary equipment rooms; its service life exceeds 25 years; and its layout is highly flexible. It can be customized according to the station’s geographical location (e.g., anti-seismic reinforcement for earthquake-prone areas) and meteorological conditions (e.g., anti-corrosion treatment for coastal areas), and supports phased construction in line with long-term planning. If the project site needs adjustment, it can be relocated and reused in a short time. In terms of appearance, it offers diverse aesthetic designs, with color painting and spraying that match the surrounding natural or architectural environment, enhancing the overall coordination of the project site.

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.
