H05z and h07z u cables are referred to 6491B nonsheath single core cables insulated with halogen-free crosslinked compound and having low emission of smoke and corrosive gases when exposed to fire with rated voltage up to and including 300/500V.

The maximum conductor operating temperature for the cables are 90℃ and for fixed wiring application. It is often referred LSZH building wire cable. H07Z-U and H07Z-R are cables for fixed wiring with voltage 450/750V. The conductor shall be class 1 or class 2. The size of cable for Class 1 is 1.5--10mm² and class 2 is 1.5 630mm². H05Z-U is for internal wiring with voltage 300/300V. The conductor shall be in class 1. The size of the cables are from 0.5-1mm².

We supply the cables according to BS EN 50525-3-41 and IEC 60227.

Application Of CU/LSZH H05Z-U H05Z-R LSZH Building Wire

H05Z-R U is normally used in industrial and agricultural workshop, heating installations or internal wiring of switchboards and distributor boards. They normally installed in conduit and trunking or can be surface nounted if used as earth cable. They are good options for using in public buildings to reduce the threat to life and equipment cased by smoke and toxic fumes. They can't be installed incontrete without mechanic protection.
