Understanding cable construction weight
Cable weight starts with the conductor. Copper often dominates total mass because it is dense. Aluminum reduces mass but usually needs more cross-sectional area. Stranded conductors follow helical paths. Their actual metal length exceeds the finished cable length. The stranding factor accounts for this difference.
Insulation surrounds each conductor or complete core assembly. Its mass depends on annular area, density, length, and coverage. Extruded layers normally use full coverage. Tapes need overlap or helical corrections. Specialty compounds vary substantially in density.
Fillers occupy spaces between insulated cores. A solid annular model can overestimate filler mass. Use an effective coverage factor for irregular voids. Bedding and inner sheaths can then be modeled as full radial layers.
Metal screens may use tapes, wires, foil, lead, or braid. The layer method works for early estimates. The detailed braid model is better when carrier, end, wire, and lay data are available.
Armor can contribute significant mass. Wire armor needs wire diameter, count, density, and lay factor. Tape armor can use the layer table. Coverage and helical factors can represent gaps and overlap.
The outer sheath is normally the final radial layer. Its outer diameter becomes the diameter used for reel calculations. Always compare the result against a production drawing or manufacturer datasheet.

Accuracy and limitations
This tool calculates geometric material mass. It does not replace certified manufacturer data. Production weight changes with conductor tolerance, compound formulation, lay length, tape overlap, eccentricity, fillers, coatings, moisture, and manufacturing variation.
Use current datasheets for lifting, transport declarations, structural support, pulling calculations, procurement, and drum selection. Safety-critical work needs qualified engineering review.
The reel model compares available reel volume with cable area. Real capacity also depends on flange clearance, bend radius, winding control, packing pattern, and allowable drum loading.
