7.8.4.21 Pset_CoaxialCable

7.8.4.21.1 Semantic definition

Properties applicable to a coaxial cable, which is a copper cable with a variable number of copper coaxial pair conductors used to transmit data by means of electrical signals, especially at radio frequency. This property set is applicable to a type or occurrence of IfcCableSegment with predefined type CABLESEGMENT.

7.8.4.21.3 Properties

Name Property Type Data Type Description
CharacteristicImpedance IfcPropertySingleValue IfcElectricResistanceMeasure

A quantity defined for a mode of propagation at a given frequency in a specific uniform transmission line or uniform waveguide by one of the three following relations: Z1 = S/ |I|2 Z2 = |U|2 / S Z3 = U / I where Z is the complex characteristic impedance, S the complex power and U and I are the values, usually complex, respectively of a voltage and a current conventionally defined for each type of mode by analogy with transmission line equations.
