Design Solution of 24kV Dry Air Insulated Ring Main UnitThe combination of Solid Insulation Assist + Dry Air Insulation represents the development direction for 24kV RMUs. By balancing insulation requirements with compactness and employing solid auxiliary insulation, insulation tests can be passed without significantly increasing phase-to-phase and phase-to-ground dimensions. Encapsulating the pole column solidifies the insulation for the vacuum interrupter and its connecting conductors.Maintaining the 24kV outgoing busbar phase spacing at 110mm,Rockwill16/08-2025 -

Technical Bottlenecks of SF₆ SubstitutionInsulation Medium Performance Gapo Dried Air/N₂ insulation strength is only 1/3 of SF₆, requiring expansion of contact gap from 60mm to ≥150mm.o Conventional spring mechanisms lack energy to drive rapid closure of large gaps, easily causing contact ablation due to pre-strike.o Synthetic gases (e.g., C4+CO₂) decompose under arcing, leading to irreversible insulation degradation.Mechanical Structural Limitationso National Grid standardization fixRockwill16/08-2025 -
Implementation Scheme for Installing Lightning Arresters or Voltage Transformers in Gas-Insulated Ring Main UnitsAccording to insulation type, ring main units (RMUs) can be categorized as gas-insulated or air-insulated. The former installs primary circuit components in a sealed metal enclosure filled with low-pressure gas (primarily SF₆ or mixed gases) as the insulating medium, using cable terminals for incoming and outgoing lines. Due to superior insulation, compact size, and modular design, they are widely used in 10kV outdoor distribution substations and prefabricated transformer stations. However, theiRockwill16/08-2025 -
