3.1 .1 bonding layer
material which is deposited on an enamelled wire and which has the specific function of bonding wires together
3.1 .2 bunched wire
winding wire consisting of a quantity of small diameter insulated wires laid-up together without predetermined geometrical position and with or without additional covering
3.1 .3 class
thermal performance of a wire expressed by the temperature index and the heat shock temperature
3.1 .4 coating
material which is deposited on a conductor or wire by suitable means and then dried and/or cured
3.1 .5 conductor
bare metal after removal of the insulation
3.1 .6 covering
material which is wound, wrapped or braided around a bare or insulated conductor
3.1 .7 crack
opening in the insulation which exposes the conductor to view at the stated magnification
3.1 .8 cure
process of converting a reactive compound into a stable, usable condition by polymerization (polycondensation and polyaddition) and/or crosslinking
[SOURCE: IEC 60050-21 2:201 0, 21 2-1 3-07, modified – At the beginning of the definition, “convert a reactive compound” has been replaced by “process of converting a reactive compound” to define the term as a process.]
3.1 .9 dual coating
insulation composed of two different materials, an underlying and a superimposed coating
3.1 .1 0 enamelled wire
wire coated with an insulation of cured resin
3.1 .1 1 grade
range of increase in dimension of the wire due to insulation.IEC 60851-1 pdf download.
