10kV 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 eco-friendly gas ring main unit is a gas switchgear independently developed by Naten. It uses a safe and eco-friendly mixed gas instead of SF6 as the insulation medium in the gas box to solve the problem of SF6 gas leakage pollution. It has a high level of operational safety and is used as the core unit in the distribution network.
The eco-friendly gas insulated ring main unit uses inert gases such as dry air, nitrogen, and C4 to provide insulation, making it more eco-friendly; The use of eco-friendly solutions is more in line with the development direction of China's power industry, so eco-friendly gas ring main unit has become a more popular type of ring main unit in China at present. Compared to conventional switchgear products, ring main unit is more lightweight, convenient for transportation and installation. Excellent intelligent design fully meets the current demand for smart grids in China, improves electricity safety, greatly increases daily work efficiency, and reduces the burden of manual management.
Our series is divided into two types: II type (lower isolation); Type IV (upper isolation)
