The RTTZ 4+1 arrangement and copper sheath are the identifying features of this fire-resistant electric power cable. Copper conductors and mineral insulation accompany its 0.6/1kV voltage designation, giving the inquiry a defined conductor material, insulation and sheath basis.
Separate the copper sheath from the conductor schedule
The sheath and the conductors are both specified as copper, but they serve separate places in the construction description. Retain the copper sheath in the material requirement while the circuit drawing defines the function and required section of each conductor in the 4+1 arrangement.
- RTTZ identifies this electric power-cable family.
- A 4+1 grouping is the actual conductor-layout choice.
- Copper is specified for the conductors and the distinct sheath.
- Mineral insulation forms part of the fire-resistant build.
- The 0.6/1kV rating states the cable's voltage designation.
Give the selected size a complete configuration
The technical choice includes a 50 mm² size reference with 4+1 cores. Show the individual conductor sections alongside that reference, then give the cable length required for the physical route. This keeps the electrical size and installation reach distinct within the same order request.
Define cable ends and the project fire requirement
Provide the receiving connections and termination details for the selected copper-sheathed RTTZ version. Identify any exact fire-performance criterion required by the circuit specification and describe the relevant installation conditions. These details connect the known fire-resistant construction to a defined project scope, allowing the requested arrangement, material build, cable reach and both end interfaces to be assessed together.
