    H05Z-U/H07Z-U/H07Z-R

    Application and Description

    These cables are designed for the internal wiring of switchboards and distributor boards with an alternating nominal voltage up to 1000 Volts or a direct voltage up to 750 volts.

    Generally install in pipes or ducts and internal wiring of appliances with maximum operating temperature 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 gasses when burnt which is particularly important where electronic equipment is installed.
