H07ZZ-F rubber LSZH single-multicore flex

H07ZZ-F rubber LSZH single-multicore flex is designed for stage technology, mobile equipment and machinery. Often used in public areas where in the case of a fire smoke emission and toxic fumes could become a danger.

Flexible multicore cables suitable for use in dry or damp rooms and (according to HD516/VDE0298-300) temporarily outdoors.

These H07ZZ-F rubber cables LSZH are designed for increased safety in the case of fire due to the virtual elimination of toxic fumes and low smoke emissions if burnt.
