Mafi girman abubuwa na RMUs sun hada da kungiyar kudin da kuma fayal. Wadannan abubuwan yana da muhimmanci wajen inganta al'adun takamakawa da kuma zama shiga rayuwa. Yawancin hanyar zuwa idan ya kai, RMUs suka iya samun kungiyar kudin da yake 1250A, musamman 630A. Idan muna nufin abin da ake kafa, ana gaba da air-insulated da SF₆ gas-insulated, domin amfani da su don kungiyar kudin, koyar kudin da kuma kontrola da ingantaccen rayuwa.

(1) Tsunan Ingantaccen. An yi amfani da electrical equipment mai SF₆ gas-insulated za a zama mai biyu. Musamman, saboda ilimin da take haifar da amfani da SF₆, an yi amfani da RMUs mai solid-insulated. Both domestic and international manufacturers have anticipated this trend and are actively promoting the research, development, and application of solid-insulated RMUs.

(2) Amfani Da Encapsulated Pole Technology. Solid insulation typically uses epoxy resin as the main insulating material and vacuum as the arc-quenching medium. By actuating the operating mechanism, functions such as load current switching are achieved, effectively controlling the power distribution system and ensuring equipment and personnel safety. The use of solid insulation significantly reduces the required phase-to-phase and phase-to-ground insulation distances within switchgear, shortening air insulation gaps from 125mm to just a few millimeters. Without SF₆ gas, the equipment is more compact compared to traditional C-GIS. Additionally, the simplified operating mechanism reduces the number of components, greatly enhancing mechanical reliability.

(3) Muhimmin Abubuwan. The main competitors of solid-insulated RMUs are air-insulated RMUs with SF₆ switches and SF₆ gas-insulated RMUs. Excluding environmental considerations, the advantages of solid-insulated RMUs are evident: first, structural simplification—by eliminating pressurized gas chambers, pressure gauges, and filling valves, reliability is improved, maintenance costs are reduced, and the switch's rated operating conditions are optimized; second, the main switch is equipped with an isolation gap, providing a clearly visible open state that fully meets power grid safety operation requirements; third, strong adaptability, enabling stable operation in harsh environments such as extreme cold and high temperatures, indicating low environmental sensitivity. External insulation primarily uses epoxy resin sleeves or insulating tubes, effectively avoiding SF₆ liquefaction at low temperatures and expansion at high temperatures.

In summary, solid-insulated RMU technology in China has matured, effectively overcoming the limitations of air-insulated and gas-insulated RMUs, and is suitable for special environments such as high altitudes and heavily polluted areas. Its widespread application will strongly promote the development of the power grid system and contribute to sustainable socioeconomic development.
