How is the cable screened to protect signals?


A continuous screen surrounds the cores to reduce electromagnetic interference and crosstalk in electrically noisy environments.

What strand construction supports Flex and durability?


Each conductor comprises seven strands of bare copper to balance flexibility with conductor integrity for repeated handling.

What fire-performance characteristics does the outer material provide?


The jacket is a low smoke, non-halogen compound formulated to emit reduced corrosive gases and limited smoke density during combustion.

How is the cable supplied for long runs?


It is available on a 305 m reel to facilitate extended continuous runs without mid-span joins.
