The 4+1 conductor arrangement gives this RTTVZ electric-power cable its specific layout. Copper conductors and mineral insulation are combined with a copper sheath, PVC outer sheath and a rated voltage of 0.6/1kV.
A 50 mm² size reference accompanies the actual 4+1 option. Use it with the section required for each conductor when defining the selected cable construction.
Preserve the four-plus-one grouping in the power drawing
Assign a required function and section to each conductor on the circuit drawing. Keep the 4+1 grouping visible with those details, allowing the cable request to identify the electrical arrangement without presuming the additional conductor's duty.
- RTTVZ is the requested electric-power cable family.
- The featured option uses a 4+1 conductor layout.
- Copper conductors are paired with mineral insulation.
- Copper sheath and PVC outer sheath are distinct specified layers.
- A 0.6/1kV designation gives the rated voltage.
Specify the interfaces of the dual-sheathed cable
Retain both sheath materials in the order specification and describe the receiving connections at the two cable ends. Include termination dimensions with the conductor drawing so the complete RTTVZ build and its end interfaces can be reviewed together.
Set the physical reach and applicable IEC requirement
State the cable length required for the installation separately from the conductor-size reference. Identify any exact IEC criterion required by the project and the conditions under which it applies. Combining that requirement with the material layers, conductor duties, route and cable ends gives the power-cable inquiry a clearly defined construction and acceptance scope.
