Product Description

    The Ring Main Unit 8MRMU was developed under Germany technology by the engineers of over ten years switchgear production and application experience. We designed it on the concept of self-contained and totally insulated switchgear for secondary power distribution network. The products conform to China national GB and IEC standards      
   The Ring Main Unit 8MRMU is insensible to the environment and it is maintenance free. All the live parts are integrated well in the gas tank which SF6 is filled at 0.03 MPa gauge pressure(relative). These parts cover bus bar system, load break switch, disconnector, circuit breaker, earthing switch , fuse holders etc. The compact system,of which up to 6 loops could be accommodated in a single gas tank, is ideal solution for the installation site with a harsh climatic condition or environmental restrictions, We have gave models for the standard specification like 12kV and 24kV. Meanwhile,we can accept OEM or ODM business.

Feature:
Compact design
Maximum 6 loops could be accommodated in a single gas tank, space-saving, maintenance free
Environment-friendly structure
Hermetically tight gas tank make the parts of the primary circuit insensitive to certain aggressive ambient conditions, such as: Saline air,Air humidity, Dust And free from foreign objects etc
Maintenance-free design
Sealed pressure systems brings high reliability and safety.Finally,It is cost-saving.  
Innovation system
Clear integration of secondary systems and combined protection and control  units is well adapted to new system conditions.  
Service life
The expected service life of gas-insulated switchgear is over 30 years. The product lifespan is 45 years
