# Mass of cable

The mass of the cable can be entered manually in the cable editor or is calculated automatically based on the dimensions of the layers and the density of the various materials.

The following is considered:

• Because the exact design of the conductor is not known, the mass is calculated based on the cross-section.
• In order to consider the increase in mass due to stranding of the conductor wires, the result is increased by 6.5%.
• For wired screen, the dimension is given but not the length of lay. The exact calculated mass is increased by 3.0%.
• For wired armour, the dimension is given including the length of lay. The mass is calculated with respect of the elongation due to the length of lay.

The mass of the cable is used for cable pulling calculations and transportation studies.
