Cable Drum Design Fundamentals
Core Diameter
The core diameter determines:
- Minimum bend radius compliance
- Cable stress during winding
- Storage capacity efficiency
Flange Design
- Prevents cable spillage
- Provides structural support
- Enables safe transportation
Key Design Principles:
Core Diameter ≥ 2 × Min. Bend Radius × Safety Factor
Flange Diameter = Core Diameter + 2 × Cable Build-up
Drum Width = Cable Length / (π × Mean Diameter)
Calculation Formulas
Core Diameter:
D_core = 2 × R_min × SF
Cable Build-up Height:
H = √((L × d) / (π × D_mean))
Flange Diameter:
D_flange = D_core + 2 × H
Example Calculation
Power Cable Drum:
Cable Diameter: 25mm
Cable Length: 1000m
Min. Bend Radius: 200mm
Safety Factor: 1.2
Core Diameter = 2 × 200 × 1.2 = 480mm
Build-up Height = √((1000 × 25) / (π × 480)) ≈ 129mm
Flange Diameter = 480 + 2 × 129 = 738mm
