1. Normal pressure sealing: The function of normal pressure sealing is to prevent the external environment from being affected, and to control external moisture from infiltrating into the interior of the inflatable compartment and reducing the insulation performance of the equipment. There is no pressure in the box, and there is no risk of leakage. The zero pressure of the main switch is the operating state, which improves the operational reliability and operating life of the equipment to ensure insulation reliability. Compared with similar products, there are no more inflatable bodies, and the safety distance of charged bodies is greater than the Chinese standard requirements for air. 2. Air insulation: The gas is not treated in any way. By improving the structure and processing technology, selecting high-performance materials, and optimizing the electric field, no non-greenhouse effect gases are used or emitted in the production and use processes, which meets the requirements of miniaturization and energy saving. Environmental protection needs. 3. Miniaturization: It is more than half smaller than the conventional XGN15, and is similar in size to the same type of inflatable cabinets. It can significantly reduce the area and space of the power distribution room and reduce construction costs. 4. Demonstration of advancement in basic requirements (product design, raw materials, key technologies, processes, equipment, etc.) and quality assurance.
