TypeMulti-Core Power Cable
Relia BBTRZ three-core cable combines copper conductors, flexible mineral insulation and an LSOH sheath for industrial power supply projects. Its fire-resistant construction and 0.6/1kV rated voltage give buyers a clear starting point when comparing a cable schedule with the required electrical installation.
Three cores for the industrial conductor schedule
The three-core arrangement should be matched to the functions defined by the circuit designer. Record each conductor's duty and required section on the schedule, rather than assigning a role solely from the core count. This keeps the cable selection connected to the industrial equipment and supply circuit it will serve.
Mineral insulation with an LSOH outer sheath
Copper describes the conductor material, mineral describes the insulation, and LSOH identifies the sheath. Keeping these layers distinct makes comparisons clearer when another cable shares the BBTRZ name. Where the installation specification names a smoke, halogen or fire-test requirement, match that exact criterion to the selected construction and its supporting documentation.
Plan the route and the cable ends together
Flexible construction is useful as a selection characteristic, while the permitted bending radius and pulling conditions still belong to the final installation plan. Check those details alongside the termination arrangement and available connection space. A coordinated route and end preparation help the installer specify the cable as a complete circuit component.
Complete the industrial order
The current option pairs three cores with 50mm2. State the required conductor section and physical cut length separately, then include the approved construction, route constraints and cable-end requirements. If the project calls for a particular IEC standard or fire survival criterion, identify its number and conditions in the enquiry so the proposed build can be checked against it.






Provide the product reference, selected configuration, quantity and destination. Confirm drawings, applicable ratings and acceptance requirements for the requested build. Lead time, shipping arrangements, charges and any return conditions should be reviewed in the agreed quotation before ordering.
