Cable Entry Design
For convenient cable connection in the field, all cables among the MV Station internal
devices are connected before delivery.
All cables between the MV Station and the external are routed through the bottom of the
MV Station. All cables come into or out of the MV Station should be protected properly, for
example, cable pipe to prevent damage by rodents. After cable connection, all cable entries
except for cable glands should be sealed by fireproof mud or other appropriate materials.
The MV Station bottom cable entries are shown below.
