12KV Gas Insulated Cabinet
RM6-12 type inflatable switchgear is a completely sealed system while all live parts and switches are installed in a stainless steel shell. The entire switchgear will not be influenced by surroundings, ensuring operational reliability and personal safety, and maintenance- free operation. By combining expandable busbars, any combination can be achieved to realize full modularity. For extended busbar safety insulation and shielding, it is highly reliable and safe. The RM6-12 inflatable switchgear can also provide TV-based automation solutions, forming the concept of ineligent switches and minimizing on- site installation and commissioning. RM6-12 type inflatable switchgear is divided into non- -extended standard configuration and extensible standard configuration. It has extremely exceptional flexibility due to the combination of full and half modules and its own scalability. It has a long life for over 30 years operated under 20℃ indoor condition.
Modular design
The basic module units are load switch modules, combined electrical modules and other special function modules. Any combination of these modules formed a common box structure. In the combination, any function is approximately the same as the internal structure of the basic module.
Normal use condition
It is applicable in the place with high and low temperature (- -40°C- +40°C), humidity and salt. It can also be used in mine and the place with high altitude. Short term water in 24 hours does not affect the use. Note: If higher altitude, please specify the altitude.
Product standard
International standard IEC60056、IEC60298、 IEC60129、 IEC60420、 IEC60265、 IEC60694 etc.
Chinese standard GB3804、GB3906、GB11022 etc.
Flexible outlet and expansion
All modules of YERM can realize side outlet and side expansion or connection and top extension connection according to users' requirements, which can meet the needs of power supply scheme to the utmost extent.
