7.4.4.20 Pset_CableSegmentTypeCableSegment

7.4.4.20.1 Semantic definition

Electrical cable with a specific purpose to lead electric current within a circuit or any other electric construction. Includes all types of electric cables, mainly several electrical segments wrapped together, e.g. cable, tube, busbar. Note that the number of conductors within a cable is determined by an aggregation mechanism that aggregates the conductors within the cable. A single-core cable is defined in IEV 461-06-02 as being 'a cable having only one core'; a multiconductor cable is defined in IEV 461-06-03 as b eing 'a cable having more than one conductor, some of which may be uninsulated'; a mulicore cable is defined in IEV 461-06-04 as being 'a cable having more than one core'.

RatedTemperature IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

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

ScreenDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

The diameter of the screen around an object (if present).

HasProtectiveEarth IfcPropertySingleValue IfcBoolean

Indicates whether the object has a protective earth connection (=TRUE) or not (= FALSE).

One core has protective earth marked insulation, Yellow/Green.

MaximumOperatingTemperature IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

The maximum temperature at which a cable or bus is certified to operate.

MaximumShortCircuitTemperature IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

The maximum short circuit temperature at which a cable or bus is certified to operate.

SpecialConstruction IfcPropertySingleValue IfcLabel

Special construction capabilities like self-supporting, flat devidable cable or bus flat non devidable cable or bus supporting elements inside (steal, textile, concentric conductor). Note that materials used should be agreed between exchange participants before use.

Weight IfcPropertySingleValue IfcMassMeasure

Total weight of object

Weight of cable kg/km.

FunctionReliable IfcPropertySingleValue IfcBoolean

Element (such as cable, bus, core) maintain given properties/functions over a given (tested) time and conditions. According to IEC standard.

ACResistance IfcPropertySingleValue IfcElectricResistanceMeasure

The resistance under AC.

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.

The maximum bending radius that the cable could withstand.

NumberOfWires IfcPropertySingleValue IfcCountMeasure

The number of wires used in the element.

InsulationVoltage IfcPropertySingleValue IfcElectricVoltageMeasure

The insulation voltage.

It indicates the wire-to-ground (metal sheath) insulation voltage or the insulation voltage between the wires.

RatedVoltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

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