RTTVZ Single-Core Copper-Sheathed Mineral-Insulated PVC Outer Sheath Fire-Protection Power Cable 0.6/1kV

This single-core RTTVZ power cable is intended for fire protection and has mineral insulation, a copper sheath and a PVC outer sheath. Copper is the conductor material, and the voltage rating is 0.6/1kV. The specific one-core identity should remain with the complete layer description when the cable is selected for its circuit.

Keep the copper sheath and PVC outer sheath separately identifiable

Both sheath descriptions belong on the construction drawing, alongside the copper conductor and mineral insulation. Use all of those layers when comparing candidate cables or reviewing end preparation. A drawing that retains the PVC outer layer as well as the copper sheath gives the termination reviewer an actual construction reference for the RTTVZ cable being considered.

What does the fire-protection circuit require from this conductor?

Specify its electrical function, required section and equipment connections using the circuit design. Keep the single-core designation explicit in that allocation. Review the proposed cable ends and compatible terminations against the complete copper/mineral/copper-sheath/PVC-outer-sheath build. Include the route and available connection space with installation instructions applicable to the selected construction.

Complete the fire-protection order with a defined scope

Confirm the conductor section for the single-core 50mm2 selection and give physical cut length independently. Retain the specified layer materials and end requirements with the approved drawing in the final schedule. Where the project calls for a particular fire-test method or survival criterion, identify the acceptance conditions and review evidence for that selected build and installation. The fire-protection application and PVC outer sheath do not supply an unstated test classification, flexibility rating or environmental limit; those requirements should be identified separately whenever the project needs them.
