24kV Eco Friendly Gas Insulated RMU

Eco-friendly	This product uses no harmful gases or greenhouse gases, and more than 95% of the materials used are eco-friendly recyclable materials; the proportion of epoxy resin parts and components is less than 5%.
Maintenance Free	All high-voltage components are either gas-sealed or metal-enclosed, preventing rust and corrosion of parts. The electrical components have a long lifespan, stable performance, and can achieve maintenance-free operation.
Higher Reliability and Security	The conductive part of the main circuit is sealed with eco-friendly gases and the high-voltage live conductors are enclosed, unaffected by changes in external environmental conditions. This allows the equipment to be used in places with harsh environments, ensuring long-term operation. It has high reliability and no risk of electric shock or fire. Excellent gas tightness ensures it can serve for 30 years without needing gas replenishment.
No Partition/Solid Seal Design	The core switch design does not use interphase insulation partitions or solid seal methods to improve heat dissipation capacity and reduce the risk of partial discharge and phase-to-phase insulation failure caused by insulation aging failure.

The environmentally friendly gas-insulated ring main units are a type of gas switchgear independently developed by Naten. They use dry air as the insulating gas, making them more environmentally friendly. The use of environmentally friendly solutions is more in line with the development direction of China's power industry. Compared with traditional switchgear products, ring main units are more lightweight, making them easier to transport and install. The advanced intelligent design fully meets the current demand for smart grids in China, enhancing electrical safety, significantly improving daily operational efficiency, and reducing the burden of manual management.
