NSRM-11 SF6 gas-insulated ring main unit

Construction of urban distribution networks in overseas countries
Adapt to the distribution network architecture of Southeast Asia, Africa, the Middle East and other regions, strictly follow the IEC 62271 international standard, customize parameters according to the voltage frequency and installation specifications of the target country, and be compatible with local mainstream distribution equipment interfaces. Faced with the climate characteristics of high temperature, high humidity, and sandstorms in some countries, the anti-corrosion coating and IP68 protection level of the gas box can effectively resist harsh environmental erosion. The remote diagnosis system can reduce the difficulty of overseas operation and maintenance, and help the local distribution network achieve stable and efficient operation.

Cross border investment projects in industrial parks
In response to the diverse load demands of cross-border industrial parks, it has a flexible modular design that can quickly adapt to the power supply requirements of different production equipment. It also supports 50Hz/60Hz frequency and wide voltage fluctuation range adaptation, and can be integrated into the local power grid without additional modifications. Sealed gas boxes can isolate workshop dust, oil pollution and other pollutants, extend equipment maintenance cycles, and with global after-sales network support, can effectively solve cross-border project operation and maintenance response problems, ensuring continuous power supply to production lines.

Supporting power distribution for oilfield exploitation
Adapting to the complex environment of remote areas and open-pit operations in oil fields, the gas box is made of stainless steel material and reinforced sealing structure, which can withstand high temperature exposure, sand and dust invasion, and short-term immersion, eliminating equipment failures caused by environmental factors. The optimized SF6 gas flow field design has high arc extinguishing efficiency and can cope with the power grid impact caused by motor start-up and load changes during oilfield exploitation, providing reliable power support for core devices such as pumping units and drilling equipment.

Port and dock power supply
In response to the serious problem of salt spray corrosion in coastal areas of ports, the equipment surface has undergone special anti-corrosion treatment, which can effectively resist the erosion of metal components by salt spray and ensure long-term outdoor operation stability. It can adapt to various types of loads such as port loading and unloading machinery, refrigeration and storage, lighting and navigation, with fast short-circuit breaking speed, and can quickly respond to sudden power supply failures. At the same time, it supports remote monitoring function, which facilitates centralized control by terminal operation and maintenance personnel and improves power supply guarantee efficiency.

Distribution of agricultural irrigation power in tropical regions
In line with the climate characteristics of high temperature, heavy rain, and high humidity in tropical regions, it has the ability to operate in a wide temperature range of -40 ℃ to+70 ℃ and anti condensation design to avoid the impact of water vapor condensation on equipment insulation performance. The compact structure can be flexibly installed in simple distribution rooms in the field, resistant to external interference such as mosquitoes and weeds, providing stable power supply for irrigation pumps, water fertilizer integrated machines and other equipment, adapting to the continuous power supply needs of agricultural production, and helping to promote the large-scale development of agriculture in tropical regions.

Exclusive power distribution scenario for foreign-funded enterprises’ factories in China: Balancing IEC international standards and domestic power supply regulations, perfectly adapting to the power supply needs of imported production equipment in foreign-funded factories, and stable operation without the need for additional conversion devices. The low-noise and explosion-proof design complies with factory safety production standards, and the sealed structure can effectively isolate impurities and water vapor in the workshop environment, reducing the probability of equipment failure and shutdown. At the same time, the long life cycle and low operation and maintenance cost characteristics meet the refined management needs of foreign-funded enterprises. This device is particularly suitable for cross-border power distribution projects that have strict requirements for international adaptability and resistance to harsh environments.
