About Cable Types

THHN/THWN

Thermoplastic insulated copper wire for building wiring in conduit

XHHW-2

Cross-linked polyethylene, rated for higher temperatures and wet locations

NM-B (Romex)

Non-metallic sheathed cable for residential wiring

ACSR/AAAC

Aluminum conductor, lighter and more economical than copper

Weight Considerations

  • • Copper cables are approximately 50% heavier than aluminum equivalents
  • • Weights shown are for standard conditions at 20°C
  • • Actual weight may vary ±5% from reference values
  • • Consider cable tray load capacity when planning installations
  • • Include drum weight for accurate logistics planning

Cable Weight Calculator Guide

Why Cable Weight Matters

In large electrical installations, the weight of the copper or aluminum cable is massive. You need to calculate it to ensure your cable trays, conduits, and pulling equipment can handle the load.

The Components

Conductor: The metal core (Copper is heavier than Aluminum).
Insulation: The plastic coating (PVC, XLPE).
Armor/Sheath: Steel or lead protection adds significant weight.

Copper vs. Aluminum

Copper

The gold standard for conductivity.

  • Density: ~8.96 g/cm³. Very heavy.
  • Use: Residential wiring, high-spec commercial.

Aluminum

Lighter and cheaper.

  • Density: ~2.70 g/cm³. 1/3 the weight of copper.
  • Use: Main service entrance lines, long transmission runs.
