IFC (IFC4X3) development Pset_DiscreteAccessoryTypeInsulator Semantic definition

Properties of an insulator. The property set can be used by the predefined type INSULATOR of IfcDiscreteAccessory. Applicable entities Properties

Name Property Type Data Type Description
RatedCurrent IfcPropertyBoundedValue IfcElectricCurrentMeasure

The current that a device is designed to handle.

RatedVoltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

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

InsulationVoltage IfcPropertySingleValue IfcElectricVoltageMeasure

The insulation voltage.

The max voltage for normal insulation operation.

BreakdownVoltageTolerance IfcPropertySingleValue IfcElectricVoltageMeasure

Nominal value of the spark gap breakdown voltage tolerance.

InsulationMethod IfcPropertyEnumeratedValue PEnum_InsulatorType

The method used to insulate.

OperationalTemperatureRange IfcPropertyBoundedValue IfcThermodynamicTemperatureMeasure

The temperature range in which the device operates normally.

CreepageDistance IfcPropertySingleValue IfcPositiveLengthMeasure

Shortest distance or the sum of the shortest distances along the surface on an insulator between two conductive parts which normally have the operating voltage between them. (IEV ref 471-01-04)

InstallationMethod IfcPropertySingleValue IfcLabel

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.

LightningPeakVoltage IfcPropertySingleValue IfcElectricVoltageMeasure

The peak lightning voltage that the insulator could withstand.

BendingStrength IfcPropertySingleValue IfcPressureMeasure

Bending strength.

RMSWithstandVoltage IfcPropertySingleValue IfcElectricVoltageMeasure

Rms value of sinusoidal power frequency voltage that the insulation of the given equipment can withstand during tests made under specified conditions and for a specified duration. (IEV ref 614-03-22)

Voltage IfcPropertyBoundedValue IfcElectricVoltageMeasure

The actual voltage and operable range.
