Four cores define this RTTZ cable for a fire-protection power specification. Copper conductors and mineral insulation are paired with fire-resistant construction and a rated voltage of 0.6/1kV.
The featured selection combines a 50 mm² size reference with the four-core arrangement. Use that combination as the starting point for a complete project cable schedule.
Give each RTTZ conductor a defined duty
Identify the function and required section of all four conductors on the circuit drawing. Keep the selected size reference with those conductor details, so the quotation describes the intended cable arrangement rather than only a model name and voltage.
- RTTZ identifies the specified cable family.
- The four-core configuration matches the actual conductor-count choice.
- Copper retains the stated conductor material for this version.
- Mineral insulation is part of the identified cable construction.
- The 0.6/1kV rating provides the voltage designation for the inquiry.
Complete the route and cable-end details
State the physical cable length required for the fire-protection circuit independently of the conductor-size reference. Include the receiving connections, termination requirements and selected sheath construction to give the ordered RTTZ build a complete material and interface scope.
Specify the applicable fire-protection criterion
The fire-resistant identity is retained for this cable, while any exact IEC or fire-performance criterion should be identified for the intended project. Match that requirement to the selected construction and installation. A drawing that joins four conductor duties, their sections, the route and both cable ends makes this RTTZ request ready for a focused technical quotation.
