WIRE & CABLE ENGINEERING

Bundle diameter estimator.

Build your bundle, see its cross-section, and plan for the space it needs.
Mixed wire diameters, manufacturing tolerances, and covering included.

01

Bundle composition

Up to 150 wires / cables

Enter finished outside diameter, including insulation. For a jacketed cable, enter the complete cable diameter once; do not also enter its internal conductors. AWG alone does not determine outside diameter.

02

Assembly assumptions

The default 10% allowance is an adjustable planning assumption for a less compact assembly. The range uses 0–20% allowance (twice the entered value), plus the wire diameter tolerances. It is not a measured confidence interval.

03

Estimated cross-section

For informational purposes only. Results are estimates and do not establish design suitability or compliance. Qualified engineering personnel must review applicable standards, aircraft and equipment requirements, manufacturer specifications, installation conditions, and the complete engineering design before use.
