H07Z-K

H07Z-K is the halogen-free single-core wire with cross-linked insulation (EI 5) for 90 °C: it gives a higher current rating than the thermoplastic H07V-K and H07Z1-K at the same cross-section. For wiring in public buildings where fire behaviour and capacity both matter. Supplied to order; the lead time is stated in the quote.

H07Z-K is a harmonised single-core, non-sheathed wire with a flexible plain copper conductor of class 5 and a halogen-free, low-smoke cross-linked (thermosetting) insulation of compound type EI 5, rated 450/750 V and manufactured in accordance with EN 50525-3-41. The cross-linked insulation permits a continuous conductor temperature of 90 °C, which gives a higher current-carrying capacity than the thermoplastic types H07V-K and H07Z1-K of the same cross-section. It is intended for fixed installation in conduit, trunking or closed installation ducts and for the internal wiring of switchgear, control panels and distribution boards, in particular where people, equipment or escape routes must be protected against corrosive gases and dense smoke in the event of fire. The wire is available in the cross-sections 1.5 to 240 mm² in a range of colours; it is not intended for direct burial, unprotected outdoor use or continuous flexing in service.
