Product Introduction
Overview of RYM6-12 Gas-Insulated Switchgear
The RYM6-12 fully insulated and hermetically sealed gas-insulated metal switchgear (referred to as "gas-insulated switchgear" for short) is also known as "common tank gas-insulated switchgear" or "SF₆ gas-insulated switchgear". All its live parts are completely enclosed in a 3.0mm-thick stainless steel SF₆ gas tank. Multiple branch switches can be installed in one gas tank, ensuring the switchgear is not affected by the environment. It truly achieves functions such as maintenance-free operation, reliable performance, and unattended operation. The gas-insulated switchgear units adopt a modular design, enabling flexible expansion and scientific combination. It is a fully insulated and hermetically sealed high-voltage switchgear.

It is suitable for 50Hz, 12kV three-phase AC high-voltage power distribution systems, and is used for receiving and distributing high-voltage electrical energy. Due to its strong adaptability, it is widely applied in industries and scenarios including mines, coastal areas, alpine and plateau regions, as well as airports, hotels, schools, subways, and municipal construction.
Main Features
1、Fully Insulated and Hermetically Sealed: All live components of the gas-insulated switchgear are enclosed in a stainless steel gas tank. The outgoing cables are connected using hermetically sealed cable plug-in units, which can effectively isolate environmental impacts.
2、Modular Design: The gas-insulated switchgear adopts a modular design, allowing flexible expansion of units. Meanwhile, its floor area is reduced by more than 50% compared with conventional high-voltage switchgear.
3、High Shell Protection Level: The gas tank of the gas-insulated switchgear is made of 3.0mm-thick stainless steel plates welded by welding robots, featuring excellent airtightness. It can ensure normal operation for 20 years, with a protection level of IP67.
4、Dual Operation Modes & High Intelligence: The gas-insulated switchgear can be equipped with either electric operation or manual operation. It also supports remote monitoring functions, achieving a high level of intelligence.
