The copper sheath is a specific part of this RTTZ power-cable build. Copper conductors and mineral insulation are combined with fire-resistant construction and a rated voltage of 0.6/1kV, forming the material basis for the project inquiry.
Keep conductor and sheath materials distinct
Retain both the copper conductor material and copper sheath in the cable specification. Identify the complete conductor arrangement required for the ordered RTTZ version, so the material schedule and circuit drawing describe the same cable.
- RTTZ names the cable family needed for quotation.
- Copper is specified as the conductor material.
- A separate copper sheath is part of this stated construction.
- Mineral insulation identifies the insulation material.
- The 0.6/1kV designation gives the rated voltage.
Complete the conductor and route schedule
Define the function and required section of every conductor alongside the 50 mm² size reference. Give the physical cable length separately and show the receiving connections, allowing both cable-end requirements to be assessed with the selected conductor arrangement.
Set the fire-resistant cable requirement
Include any exact project fire criterion that applies to the RTTZ cable and its installation conditions. Confirm the termination arrangement for the selected copper-sheathed build, keeping the end interfaces with the material and conductor schedule. A quotation request that contains these details gives the project a defined cable configuration, required route length and acceptance scope for review.
