Permissible Wire/Cable Tension
The following shows the permissible tensions of cables and wires for internal wiring or external interconnection of electronic equipment during wiring or installation. A load within the permissible tension range generates no permanent strain, and changes in dimension or rises in conductor resistance are negligible.
Permissible tension is calculated by adding all cross section of wire/cable conductors and multiplying the sum by a constant.
Maximum permissible tension (N) = Conductor specific constant (MPa) x Total cross section of conductor (㎟)
Total cross section of conductor (㎟)= Wires under tension x conductor cross section (㎟)
Permissible Tension Constants
Material | Approx. Fracture Load (MPa) | Conductor Specific Constant (MPa) |
Annealed Copper for Electrical Use, Oxygen-Free Annealed Copper | 〜275 | 71 |
Copper Alloy, Copper-Clad Steel Wire (Soft) | 343〜 | 115* |
Aluminium | 〜190 | 39 |
