What is ASNA RMU?
ASNA means:Atmospheric pressure Sealed Nature-Air insulated RMU
ASNA is a brand new type of RMU that uses nature-air as the main insulation medium.
Its main electrical circuits are sealed within an Atmospheric pressure sealed cabinet that maintains the same pressure as the surrounding environment and is equipped with filtration and pressure balance functions.
During its entire life cycle, there is no risk of air leakage, no need for pressure monitoring, and it can prevent dust, solid particles, salt fog particles, etc. from entering the sealed cabinet .

FAQ
-
How does the RMU ensures safe and reliable operation?
A:The ASNA RMU achieves safe and reliable operation through three key aspects:
First, its atmospheric pressure fully sealed system acts as a protective barrier, shielding the RMU from external environmental influences and ensuring stable operation at all times.
Second, the single-phase insulation design inside the switchgear eliminates the risk of internal arcing explosions, further enhancing operational safety.
Third, Eliminate the risk of insulation performance decline and potential discharge caused by the drop in gas pressure inside the cabinet -
What is the installation requirement?
A:The ASNA RMU is a fixed structure that can be placed in an electrical sealed cabinet or a box-type substation.Reserve an operating space of 80CM is retained in front of the RMU. Cable installation adopts the way of bottom in and bottom out. If you need other installation methods, please contact us. -
Is there any possibility of combining the HM POWER's RMU with other brands' switchgear?
A:In principle, it is not allowed.We do not recom erent brands of switchgear vary in their plug designs, circuit configurations, and electrical parameter matching.
Combining switchgear from different brands may lead to compatibility issues, which pose potential safety -
Apart from CB unit, are there any other types of unit?
A:In addition to CB unit, there are also Metering unit, PT unit, Busbar sectionliser unit, etc. Different unit types can be configured according to different schemes
The designs of HMpower vary with the changes in the market.
