Description
The 38.5kV 44kV 45kV 46kV Maintenance-Free Environmental Protection Gas Ring Network Cabinet is a high-performance medium-voltage power distribution device designed for modern smart grids. It integrates eco-friendly insulating gas technology with maintenance-free design, effectively replacing traditional gas-insulated equipment that relies on high-GWP (Global Warming Potential) gases. As a core component in power distribution systems, it is widely used in urban distribution networks, industrial parks, and commercial complexes—providing stable, safe, and low-carbon power support for end users. By optimizing the gas chamber structure and adopting high-quality sealing materials, it eliminates the need for regular gas replenishment and component inspection, while the environmentally friendly gas meets international low-carbon standards, aligning with global energy conservation and emission reduction goals.
Feature
Dual Advantages of Environmental Protection & Maintenance-Free：Adopts low-GWP environmental protection gas (compliant with eco-friendly standards) to avoid environmental pollution; the hermetic gas chamber and wear-resistant components realize long-term maintenance-free operation, reducing operation and maintenance costs.
High Operational Safety & Stability：Equipped with advanced gas insulation technology, it has strong resistance to humidity, dust, and corrosion; the built-in overvoltage and short-circuit protection functions ensure stable power supply even in harsh working environments.
Compact Design for Flexible Installation：The compact structure saves installation space, making it suitable for narrow areas such as urban underground power stations and industrial workshops; it supports modular combination to meet diverse distribution network layout needs.
Smart Monitoring for Predictive Management：Optional intelligent online monitoring system tracks gas pressure, temperature, and operating status in real time; it sends early warnings for abnormal conditions, helping users achieve predictive maintenance and improve grid management efficiency.

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 -
