BOSCO Seismic Kit Bellecore
elegance, ergonomics and adaptability
The seismic risks are those related to the vibration of the ground. Landslides, cracks in the ground, tsunamis - these are all seismic risks. Generally, they are mostly evaluated in terms of damage to structures and things.
Our cabinets accompanied with Kit Bellcore 4 and Kit Bellcore 2 are tested with specific configurations in specific circumstances and achieve specific results certified in the attached documents in this page.
BTDA cabinet with seismic kit
The Bellecore 3 Seismic Kit - Bellecore 4 is compatible and installable to the BTDA series.
- Height 2000
- Width 800
- Depth 800
- Socket 100-200
Test results Bellcore 4
These are the results of the tests for earthquake resistence (Zone 4, Telcordia/Belcore code)
Results - Resonance Frequency
Axis | Frequency [Hz] |
X | 9.0 |
Y | 6.4 |
Z | 47.5 |
Seismic test results
R4-68: No structural damage detected |
R4-74: The structure has no welds. |
R4-69 : The oscillations in the upper part are: - axis-X: 10,6 mm - axis-Y: 26,5 mm - axis-Z: LVDT no measure was taken |
O4-75: The structure is designed for a mounting base. |
R4-70, O4-71: The lower natural frequency is 6.4 Hz |
O4-76: Tensile tests not carried out, because the structure is tested with seismic waves. |
R4-72, O4-73: The seismic tests caused extensive damage, so the equipment is no longer functional |
R4-77, O4-78, O4-79: Anchors are unknown and therefore omitted from the test configuration |
Test results Bellcore 2
These are the results of the tests for earthquake resistence (Zone 2, Telcordia/Belcore code)
Results - Resonance Frequency
Axis | Frequency [Hz] |
X | 7.4 |
Y | 8.9 |
Z | 29 |

Base Zone 4
Special base made of 30/10 thick sheet steel bent and welded together, painted with RAL 7035 epoxy powder.
Structure Zone 4
Seismic Kit consists of three brackets in galvanized 30/10 mm thick steel, mounted at the top, bottom and center on both sides.
Internal plate Zone 4
Special Internal plate in galvanized steel, thickness 25/10 mm, fixed by robust crossbars of 30/10 mm thick galvanized sheet metal.
Two additional reinforcements, in steel 25/10 mm thick, must be applied in case of loads heavier than 100kg.
