BBTRZ 5-Core Copper Mineral-Insulated LSOH Fire-Resistant Power Cable for Fire Protection 0.6/1kV

Five copper cores, mineral insulation and an LSOH sheath define this BBTRZ power cable for fire-protection systems. Its rated voltage is 0.6/1kV, with fire resistance included in the stated construction. The five-core arrangement can be checked against the project's individual conductor schedule.

Build the specification around five conductor duties

Assign the function, required section and equipment connection of each conductor from the circuit drawing. A five-core arrangement does not establish those individual duties by itself. Keep the allocation with the approved cable construction so the termination review and order schedule use a clear electrical reference. Include the intended route and connection space when completing that drawing.

Retain the LSOH sheath in performance comparisons

Copper identifies the conductors, mineral identifies the insulation and LSOH identifies the sheath. Preserve all three requirements when comparing alternative fire-protection power cables. If the project specifies exact fire-test conditions, a survival duration, smoke limits or halogen criteria, check those requirements for the selected build. The ordinary construction descriptions should stay connected to the actual cable configuration and installation conditions required by the project.

Complete a clear cable order

The current technical selection reads 50mm2 with five cores. Confirm the individual conductor sections and physical cable length separately, then include the agreed allocation, material layers and cable-end details in the order description. Review terminations and cable-end preparation against the approved construction. Keep the final drawing with the fire-protection schedule so the electrical configuration, physical quantities and required performance scope can be reviewed together. Include the agreed installation constraints with the final cable-end review.
