Cable Transit Frames · MCT Product Line
Frames engineered to drop into the cut-out you already have.
DEWIN cable transit frames are dimensioned to common 120-frame standards, so a purchasing engineer can qualify a second source without redesigning the enclosure. Weld-in and lightweight compression-integrated families cover most BESS, data centre and switchgear cut-outs.

Applications
Where these frames are already in service.
Energy storage
BESS containers
Entries between battery racks and control compartments, sealed against dust, water and fire spread within the frame's rated cavity.
Sizing guide →Data centre
Modular data centre halls
Dense cable penetrations through prefabricated wall panels, re-openable for later capacity additions without replacing the frame.
Sizing guide →Switchgear
Switchgear panels
Standard cut-outs mean an existing panel design needs no modification when qualifying DEWIN as a second source.
