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
