7.4.4.19.1 Semantic definition

Properties specific to busbar cable segments.

7.4.4.19.2 Applicable entities

7.4.4.19.3 Properties

Name Property Type Data Type Description
IsHorizontalBusbar IfcPropertySingleValue IfcBoolean

Indication of whether the busbar occurrences are routed horizontally (= TRUE) or vertically (= FALSE).

NominalCurrent IfcPropertySingleValue IfcElectricCurrentMeasure

The nominal current that is designed to be measured.

UltimateTensileStrength IfcPropertySingleValue IfcForceMeasure

Indicates the maximum stress that a material or element can withstand before breaking while being stretched or pulled.

ACResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under AC.

ThermalExpansionCoefficient IfcPropertySingleValue IfcThermalExpansionCoefficientMeasure

Quantity characterizing the variation with thermodynamic temperature T of the distance l between two points of a body, under given conditions (IEC 113-04-27). The ratio is defined per Kelvin.

CurrentCarryingCapacity IfcPropertySingleValue IfcElectricCurrentMeasure

Maximum value of electric current which can be carried continuously by a conductor, a device or an apparatus, under specified conditions without its steady-state temperature exceeding a specified value. Based on IEC60826-11-13. NOTE: The temperature specified value is maximum Design Ambient Temperature.

DCResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under direct current and 20 degrees centigrade.

MassPerLength IfcPropertySingleValue IfcMassPerLengthMeasure

Mass per length, i.e. mass of a beam with a unit length of extrusion. For example measured in kg/m.

TensileStrength IfcPropertySingleValue IfcPressureMeasure

Indicates the ability to withstand breakage apart under applied force.

YoungModulus IfcPropertySingleValue IfcModulusOfElasticityMeasure

A measure of the Young's modulus of elasticity of the material.

CrossSectionalArea IfcPropertySingleValue IfcAreaMeasure

Cross section area of the phase(s) lead(s).

InsulationMethod IfcPropertyEnumeratedValue PEnum_InsulatorType

The method used to insulate.

OverallDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

The overall diameter of a object.

OperationalTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

The temperature range in which the device operates normally.

Allowable operation ambient air temperature range.

RatedVoltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum.
