Is the cable screened for interference protection?
No, the construction is unscreened, relying on proper routing and system earthing to manage electromagnetic interference.
What safety standards does the sheath comply with for enclosed spaces?
The sheath meets low-smoke and halogen-free material standards and conforms to relevant tests for flame propagation and gas acidity to reduce hazard in confined areas.
How large is the overall cable in cross section relative to installation routes?
The cable has an outside diameter of 7.3mm, permitting use through standard conduit and cable trays where space is limited.
What approvals support use in regulated installations?
Approvals include RoHS and national conformity marking, alongside several IEC and EN test standards for fire behaviour and emissions.
Can it be ordered in extended lengths for long runs?
The product is supplied on a 500m reel to accommodate extended installations and minimise joins.
