Name Type Mult. Description Owning Classifier
identification String 1

Specifies a unique identification of the specification. The identification is guaranteed to be unique within the document containing the specification. Over all VEC-documents a Specification-instance can be trusted to be identical if the DocumentVersion-instance is the same (see DocumentVersion) and the identification of the Specification is the same.

description AbstractLocalizedString 0..*

Specifies additional, human readable information about the specification.

crossSectionArea NumericalValue 0..1

Specifies the cross section area of the conductor (e.g. 0,5 mm²). The cross section area is a nominal value, which refers to the conducting properties of the conductor normalized to the properties of a full material core.

massInformation MassInformation 0..1

Specifies the mass information of the conductor. In most cases this mass information is known as copper weight and is normally specified as mass per length (e.g. gram per meter).

material Material 0..*

Specifies the material of the conductor.

resistance NumericalValue 0..1

Specifies the electrical resistance of the conductor. In most cases this is specified as resistance per length (e.g. Ohm per meter).

structure String 0..1

Specifies the structure of the conductor (e.g. symmetrical, asymmetrical).

type String 0..1

Specifies the type of the conductor. This should be an enumeration of values defined in a conformance class (e.g. solid, meshwork).

numberOfStrands NumericalValue 0..1

Specifies the number of strands in one conductor. If the conductor is solid than the number of strands would be one.

platingMaterial Material 0..*

Specifies the plating material of the conductor.

strandDiameter NumericalValue 0..1

Specifies the diameter of a single strand in the conductor.

voltageRange NumericalValue 0..1

Specifies the voltageRange for which the conductor is approved.

opticalTissueDensity NumericalValue 0..1

Defines the optical tissue density of the strands of a shield. This is defined as a value in percentage.

windingType String 0..1

Defines the type of winding of the shield. E.g. if the shield is a sheet, it can be folded around the inner elements and along them like a cigarette paper or it can be winded around them like the taping of a harness. Both types result in different manufacturing and EMC properties.
