RYM6-12 inflatable cabinet overview
RYM6-12 fully insulated and fully enclosed inflatable metal switch cabinet (inflatable cabinet for short) is also called a box-type inflatable cabinet and sf6 inflatable cabinet. All its live parts are completely sealed in a 3.0mm thick stainless steel SF6 gas box. Multiple branch switches can be installed in one gas box to make the switch device not affected by the environment. It truly realizes the functions of maintenance-free, reliable operation and unattended operation. The inflatable cabinet unit adopts modular design and can be flexibly expanded and scientifically combined. It is a fully insulated and fully enclosed high-voltage switch cabinet. It is suitable for 50HZ, 12kv three-phase AC high-voltage power distribution system to receive and distribute high-voltage electric energy. Because of its strong adaptability, it is widely used in mining, coastal areas, mountain and plateau areas, and is used in airports, hotels, schools, subways, municipal construction and other industries.
main feature
1. Fully insulated and fully enclosed, all live equipment of the inflatable cabinet is encapsulated in a stainless steel air box, and the outgoing cables are connected with closed cable plug-ins, which can effectively isolate environmental influences.
2. The inflatable cabinet adopts a modular design, which can flexibly expand the unit. At the same time, it occupies more than 50% less area than conventional high-voltage switch cabinets.
3. The shell has high protection level. The air box of the inflatable cabinet is made of 3.0mm thick stainless steel plate and welded by a welding robot. It has good air tightness and can guarantee normal use for 20 years. The protection level is IP67.
4. The inflatable cabinet can be operated electrically or manually, and at the same time it can realize remote monitoring function and is highly intelligent.
