H05Z-U / H07Z-U / H07Z-R German Standard LSZH Cable – VDE 0282

Low Voltage Power Cables
Description

German Standard Industrial Cable H05Z-U / H07Z-U / H07Z-R

Product Overview

The H05Z-U, H07Z-U and H07Z-R are German standard industrial cables 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. They are generally installed in pipes or ducts and for internal wiring of appliances with a maximum operating temperature of 90°C.

These cables are suitable for 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.

The cables are manufactured to <HAR> HD 22.9 S2, VDE-0282 Part-9, BS 7211, IEC 60754-2, EN 50267, VDE 0482-267, and comply with the CE Low Voltage Directive 73/23/EEC and 93/68/EEC. They are also ROHS compliant.

Key Features & Benefits

  • LSZH Construction: Low smoke, zero halogen (LSOH) insulation and construction minimise toxic fumes and smoke in fire conditions.

  • No Corrosive Gases: Produces no corrosive gases when burnt, protecting electronic equipment.

  • High Temperature Resistance: Maximum operating temperature of 90°C.

  • Flame Retardant: Complies with IEC 60332.1.

  • Cross-Linked Polyolefin Insulation: EI5 core insulation for enhanced thermal and electrical performance.

  • Voltage Ratings: 300/500V (H05Z-U); 450/750V (H07Z-U / H07Z-R).

  • Test Voltage: 2500 volts.

  • Insulation Resistance: 10 MΩ x km.

  • Short Circuit Temperature: +250°C.

  • ROHS Compliant: Meets environmental and health requirements.

  • Standard Compliant: <HAR> HD 22.9 S2, VDE-0282 Part-9, BS 7211, and related standards.
