H05Z-K / H07Z-K BS EN 50525-3-41 Single Core Class 5 Flexible Copper Harmonised Cable LSZH Insulation Electrical Wire
Application
In pipes or ducts and internal wiring of appliances with maximum operating temperatures of 90°C, and generally in areas (such as public and government buildings) where smoke and toxic fumes may cause a threat to life and equipment. The cables produce no corrosive gases when burnt which is particularly important where electronic equipment is installed.
