Defining cables in lines and circuits

Cables can be defined in the "Cable" section, located on the left-hand side of the editing panels for lines, circuits, panels and special lines.

The definition options available in this section vary depending on whether a "Cable (IEC)" or "Cable (ANSI)" is defined in the "Conductor" option in the "Description" section of the line, circuit, switchboard or special line. They are as follows:

Note:

To work with IEC or ANSI cables, users must have previously enabled the possibility of working with each type of cable in the "Configuration" option of the "Project" group.

Defining IEC cables

If an IEC standard cable is defined, the program allows the following parameters to be configured:

Nominal voltage (0,6/1 kV / 450/750 V / 300/500 V)
Material (Copper/Aluminium)
Insulation
Reinforcement (optional)
- Selecting the reinforcement material
Roof (optional)
- Selecting the reinforcement material
Fire reaction class
Phase
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor
Neutral
This can be "The same as the phase" or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor
Protection
This can be "The same as the phase", "Without conductor" ( if there is no need for the protective conductor distribution) or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor
Protective earth and neutral (PEN)
Only available in polarity 3F + CPN, 2F + CPN or F + CPN. This can be "The same as the phase", "Without conductor" or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor

By clicking on the "Consult selection" option, a panel is displayed which provides clarification about the data entered, as well as a current-time graph of the thermal resistance of the cable.

Defining ANSI cables

If a cable is defined under the ANSI standard, the program allows the following parameters to be configured:

Voltage rating (0,6/1 kV / 450/750 V / 300/500 V)
Conductor material (Copper / Aluminium)
Insulation
Maximum operating temperature
Conduit installation (Magnetic / Not magnetic)
Phase
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor
Neutral
This can be "The same as the phase" or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor
Protection
This can be "The same as the phase", "Without conductor" ( if there is no need for the protective conductor distribution) or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conduct
Protective earth and neutral (PEN)
Only available in polarity 3F + CPN, 2F + CPN or F + CPN. This can be "The same as the phase", "Without conductor" or "Other":
- Single-core / Multi-conductor
- Number of conductors per pole x Section of the conductor

By clicking on the "Consult selection" option, a panel is displayed which provides clarification about the data entered, as well as a current-time graph of the thermal resistance of the cable.

Notes:

The checks carried out are adapted to the cable selection. For example, the IEC cable ampacity test is replaced by the cable ampacity test according to the American NEC (National Electrical Code) standard for ANSI cables.

The panel for defining the type of conduit and the installation method is also adapted to the cable selection made.

The program incorporates the grouping correction factor tables for all installation methods in accordance with IEC 60364-5-52. Some tables for certain installation methods may not provide a grouping correction factor for a large number of conductors, in which case the program uses the most unfavourable factor from the table and indicates this with a warning message in the ampacity test. This extension can be used for cables with more than 2500 A for transformer outgoing current, for example.
