7.4.2.5 IfcCableSegmentTypeEnum
7.4.2.5.1 Semantic definition
The IfcCableSegmentTypeEnum defines the range of different types of cable segment that can be specified.
7.4.2.5.2 Type values
| Type | Description |
|---|---|
BUSBARSEGMENT
|
Electrical conductor that makes a common connection between several electrical circuits. Properties of a busbar are the same as those of a cable segment and are captured by the cable segment property set. |
CABLESEGMENT
|
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 core segments or conductor segments wrapped together. |
CONDUCTORSEGMENT
|
A single linear element within a cable or an exposed wire (such as for grounding) with the specific purpose to lead electric current, data, or a telecommunications signal. |
CONTACTWIRESEGMENT
|
An electric conductor of an overhead contact line with which the current collectors make contact. Note: definition from IEC60050 811-33-15. |
CORESEGMENT
|
A self contained element of a cable that comprises one or more conductors and sheathing.The core of one lead is normally single wired or multiwired which are intertwined. |
FIBERSEGMENT
|
A fiber segment is an individual optical fiber used in telecommunication systems to transmit data by means of optical signals. |
FIBERTUBE
|
A fiber tube is semi-rigid hollow plastic tube with a very small radius that houses and protects a certain number of optical fiber segments. An optical cable segment may contain many fiber tubes. |
OPTICALCABLESEGMENT
|
An optical cable segment is a cable segment that contains a variable number of optical fiber segments. |
STITCHWIRE
|
A stitch wire consists of auxiliary wires and different components (clamp) used in stitched suspension. |
WIREPAIRSEGMENT
|
A pair of conductors contained in a copper cable. The pair is always used together to form a circuit to transmit data by means of electric signals. |
USERDEFINED
|
User-defined type. |
NOTDEFINED
|
Undefined type. |
