Overview
NG7-40.5 series SF6 gas-insulated switchgear is a new generation of miniaturized products designed and manufactured by IEC 62271-200.
It has a variety of combinations and can be flexibly extended, which not only meets the requirements of power distribution, but also meets the needs of various secondary distribution application for flexible compact switchgear. It is widely used in public power grids, utilities, rail transit, new energy E-house, solar farm, wind farm, data center and other new energy fields.
The NG7 series switchgear employs a full-seal structure scheme and modular design. All live parts are placed in the sealed shell, which makes them free from the impact of external environment and ensures the requirements of high reliability and security. Additionally, automation solutions can be configured to realize intelligent control.

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,16/08-2025 -
Optimization Design Scheme for the 12kV Air-Insulated Ring Main Unit Isolating Gap to Reduce Breakdown Discharge ProbabilityWith the rapid development of the power industry, the ecological concept of low-carbon, energy-saving, and environmental protection has been deeply integrated into the design and manufacturing of power supply and distribution electrical products. The Ring Main Unit (RMU) is a key electrical device in distribution networks. Safety, environmental protection, operational reliability, energy efficiency, and economy are inevitable trends in its development. Traditional RMUs are primarily represented16/08-2025 -
Analysis of Common Problems in 10kV Gas-Insulated Ring Main Units (RMUs)Introduction:10kV gas-insulated RMUs are widely used due to their numerous advantages, such as being fully enclosed, possessing high insulation performance, requiring no maintenance, having a compact size, and offering flexible and convenient installation. At this stage, they have gradually become a critical node in urban distribution network ring-main power supply and play a significant role in the power distribution system. Problems within gas-insulated RMUs can severely impact the entire di16/08-2025 -

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 fix16/08-2025 -
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, thei16/08-2025 -
