Name | Type | Description |
DesignAmbientTemperature |
P_BOUNDEDVALUE
/
IfcThermodynamicTemperatureMeasure
|
| Design Ambient Temperature | The highest and lowest local ambient temperature likely to be encountered. |
|
UserCorrectionFactor |
P_SINGLEVALUE
/
IfcReal
|
| User Correction Factor | An arbitrary correction factor that may be applied by the user. |
|
NumberOfParallelCircuits |
P_SINGLEVALUE
/
IfcInteger
|
| Number Of Parallel Circuits | Number of parallel circuits. |
|
InstallationMethod |
P_SINGLEVALUE
/
IfcLabel
|
| Installation Method | Method of installation of cable/conductor. Installation methods are typically defined by reference in standards such as IEC 60364-5-52, table 52A-1 or BS7671 Appendix 4 Table 4A1 etc. Selection of the value to be used should be determined from such a standard according to local usage. |
|
InstallationMethodFlagEnum |
P_ENUMERATEDVALUE
/
IfcLabel
/
PEnum_InstallationMethodFlagEnum |
| Installation Method Flag Enum | Special installation conditions relating to particular types of installation based on IEC60364-5-52:2001 reference installation methods C and D. |
|
DistanceBetweenParallelCircuits |
P_SINGLEVALUE
/
IfcLengthMeasure
|
| Distance Between Parallel Circuits | Distance measured between parallel circuits. |
|
SoilConductivity |
P_SINGLEVALUE
/
IfcThermalConductivityMeasure
|
| Soil Conductivity | Thermal conductivity of soil. Generally, within standards such as IEC 60364-5-52, table 52A-16, the resistivity of soil is required (measured in [SI] units of degK.m /W). This is the reciprocal of the conductivity value and needs to be calculated accordingly. |
|
CarrierStackNumber |
P_SINGLEVALUE
/
IfcInteger
|
| Carrier Stack Number | Number of carrier segments (tray, ladder etc.) that are vertically stacked (vertical is measured as the z-axis of the local coordinate system of the carrier segment). |
|
MountingMethod |
P_ENUMERATEDVALUE
/
IfcLabel
/
PEnum_MountingMethodEnum |
| Mounting Method | The method of mounting cable segment occurrences on a cable carrier occurrence from which the method required can be selected. This is for the purpose of carrying out 'worst case' cable sizing calculations and may be a conceptual requirement rather than a statement of the physical occurrences of cable and carrier segments. |
|
IsHorizontalCable |
P_SINGLEVALUE
/
IfcBoolean
|
| Is Horizontal Cable | Indication of whether the cable occurrences are mounted horizontally (= TRUE) or vertically (= FALSE). |
|
IsMountedFlatCable |
P_SINGLEVALUE
/
IfcBoolean
|
| Is Mounted Flat Cable | Indication of whether the cable occurrences are mounted flat (= TRUE) or in a trefoil pattern (= FALSE). |
|
CurrentCarryingCapasity |
P_SINGLEVALUE
/
IfcElectricCurrentMeasure
|
| Current Carrying Capasity | 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. |
|
MaximumCableLength |
P_SINGLEVALUE
/
IfcLengthMeasure
|
| Maximum Cable Length | Maximum cable length based on voltagedrop. NOTE: This value may also be specified as a constraint within an IFC model if required but is included within the property set at this stage pending implementation of the required capabilities within software applications. |
|
PowerLoss |
P_SINGLEVALUE
/
IfcElectricCurrentMeasure
|
| Power Loss | Total loss of power across this cable. |
