RTTZ Copper Mineral-Insulated Fire-Resistant Power Cable for Fire Protection Rated 0.6/1kV

The RTTZ power cable is intended for fire-protection systems and uses copper conductors with mineral insulation. Its rated voltage is 0.6/1kV and fire resistance is stated for the construction. Agree the final conductor arrangement and sheath through the circuit design before completing the selected cable configuration and connection requirements.

Agree the fire-protection allocation

Define the actual core layout, with a section, electrical function and equipment connection for every conductor. Keep the agreed arrangement with the proposed cable ends on the circuit drawing. The completed allocation should identify one definite electrical configuration before conductor quantities and terminations are finalized for the order. Retain the individual requirements with the schedule used to describe the fire-protection circuit.

Complete the material and installation review

Preserve copper conductor material and mineral insulation while agreeing the sheath for the actual cable build. Use the complete layer drawing to compare alternatives and review preparation and compatible terminations. Obtain installation information applicable to the selected construction. Consider the intended route with equipment access and available connection space so the cable-end and material reviews refer to the same build.

Retain exact criteria and physical length

Where an IEC method or classified fire criterion is required, identify its acceptance conditions precisely and review matching evidence for the chosen construction and installation. Ordinary fire resistance remains a supported function while an exact measured result has its own scope. Confirm individual conductor sections for the 50mm2 selection after the arrangement is settled, and give physical cable cut length independently. Include the approved allocation, selected sheath and agreed end requirements with the final schedule and exact project criterion.
