7.8.4.7.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| ACResistance | IfcPropertySingleValue | IfcElectricResistanceMeasure |
The resistance under AC. |
|
| UltimateTensileStrength | IfcPropertySingleValue | IfcForceMeasure |
Indicates the maximum stress that a material or element can withstand before breaking while being stretched or pulled. |
|
| CatenaryWireType | IfcPropertySingleValue | IfcLabel |
Indicate the type of Catenary wire. |
|
| ThermalExpansionCoefficient | IfcPropertySingleValue | IfcThermalExpansionCoefficientMeasure |
A measure of the expansion coefficient for warming up the material about one 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. |
|
| LayRatio | IfcPropertySingleValue | IfcPositiveRatioMeasure |
The ratio between lay length and the diameter of the single conductor. |
|
| MassPerLength | IfcPropertySingleValue | IfcMassPerLengthMeasure |
