| Structural characteristics | |
| 1, the device uses 8MF steel main frame, frame by assembling and
welding two part structure. Are installed on the main frame modulus
hole E = 20m rTI2, device strictly separate the function room,
which features a single compartment is divided into no room, bus
room, cable rooms, each unit features independent. 3 drawer
changing only the height change, its width, depth unchanged. The
same functional unit of the drawer has a good interchangeability. |
