KEY FEATURES

Class 2 plain or metal-coated annealed copper, with Class 1 and Class 5 offered as options; mica glass tape and thermosetting XLPE insulation.
Unarmoured construction with a thermoplastic halogen-free ST8 outer sheath.
Construction schedule: 1.5-1000 mm² single-core Class 2 copper.

SELECTION NOTES

Specify the required circuit-integrity test method, classification and duration together with compatible supports and terminations. Match the selected cable and installation system to the project fire strategy.
Apply the published current-rating and voltage-drop references to the matching circuit arrangement, installation method and temperatures, including the applicable correction factors.
Circular conductors use 4 times overall diameter up to 25 mm cable diameter and 6 times above 25 mm; shaped conductors use 8 times overall diameter. State any UV, oil, hydrocarbon, rodent or termite sheath options in the order.
