Almost all characteristics of conductors, resistance, current carrying capacity etc. Mechanical properties measurement – Room temperature tensile test of reacted Nb3Sn 600028 superconductors. This document is one considered Fundamental in that it does not contain reference to any other standard.

Electronic characteristic measurements – Intrinsic surface impedance of superconductor films at microwave frequencies.

The main problem being that not all copper has the same resistivity value, so, for example, a 4mm 2 conductor from two different suppliers may have different resistance values.

What is a standard? The standard is now in your shopping cart. Instead this document describes conductors iecc their nominal size, determined by resistance rather than physical dimensions.

This engineering-related article is a stub. Message to your colleague. However this document allows an easy reference whereby the standard conductor sizes and reference to physical dimensions are maintained but given an exact meaning in terms of the electrical characteristics of a conductor. 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 annealed copper.

The cross-sectional area is also related to the maximum current ie a wire can carry safely. Report error on page.

Shopping cart Close cart 0, foreach: This document and its precursors were created due to a need for a standard definition of cable conductor size. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance.
