MSR Green-24 Environmental protection ring network cabinet
MSR Green-24 Environmental protection ring network cabinet
Product Introduction:
MSR-Green series ring network cabinet is a kind of scalable ring network cabinet used in secondary distribution network, with side expansion and top expansion schemes. The ring network cabinet offers more than 10 standard combination forms, and its perfect unity of common box unit combination and single box flexible expansion can meet the application requirements of most 24 kV distribution networks.
The stainless steel chamber of the MSR-Green series ring cabinet is filled with dry air, which completely seals all live parts and switches and isolates them from the outside world. This fully sealed system protects the internal switches and all live parts from changes in the external environment, ensuring high reliability, personnel safety and virtually maintenance-free. Dry air GWP value ≤1, no greenhouse effect, more in line with the trend of low-carbon environmental protection.
MSR-Green series ring cabinet is suitable for the following use places:
Compact secondary substation
Small industrial and mining enterprises
Hotels, shopping malls, office buildings, commercial centers, etc
Product characteristics
The design and selection are flexible, and the plug-in bus connection makes all kinds of connection schemes especially convenient, and the later expansion is smooth
Plug-in design: left and right expansion, top expansion
Complete scheme: can meet the upper and lower isolation mode
Safety and environmental protection: dry air insulation
Insulation method: solid + environmental protection gas composite insulation
Arc extinguishing mode: vacuum + environmental gas
