What technical parameters and environmental considerations determine cable drum design and storage requirements?

Cable drum configurations are engineered based on material composition (plywood, timber, or metal), load - bearing capacity matching cable weight classifications, and lifecycle requirements (single - use vs. reusable systems). Critical dimensional parameters include flange height (D), core barrel diameter (d), and drum width (B/B), which dictate cable winding capacity and stability during transport.Storage protocols vary by drum type: plywood drums require moisture barriers for outdoor placement, while wooden variants demand protective lagging to prevent degradation in humid environments. All drums must be positioned on flat, drained surfaces with UV - resistant covers to mitigate sunlight - induced cable insulation deterioration. Mechanical protection measures include edge - facing storage orientation (never resting on flanges) and anti - roll securing systems to prevent structural misalignment damage during handling. Environmental sealing is mandatory for outdoor storage to prevent water ingress into cable windings, preserving dielectric integrity until installation.
