In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, 6028 than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance. This document and its precursors were created due to a need for a standard definition of cable conductor size.

This article needs additional citations for verification.

The cross-sectional area is also related to the maximum current that a wire can carry safely. Report error on page. Read more about SIS Subscriptions. Mechanical properties measurement – Room temperature tensile test of reacted Nb3Sn composite superconductors. English French Written by: This is 06028 key distinction as it makes a standardized definition of conductors based solely on their electrical characteristics.

Specifies values of the physical properties of annealed copper and how the conductivity of commercial annealed copper can be calculated and expressed as a percentage of standard 600028 copper. Retrieved from ” https: The current version is Third Edition [1] Among other things, it defines a set of standard wire cross-sectional areas:. Unsourced material may be challenged and removed.
