Single-core halogen-free cable H07Z-K 1x4 mm² white, cardboard roll 51791

Single-core halogen-free wire – safety and reliability of installation

This white single-core H07Z-K wire with a cross-section of 1x4 mm² combines safety and functionality. Made of stranded copper with halogen-free insulation, it minimizes the risk of toxic gas formation in the event of a fire. This is particularly important in installations where high fire protection standards are required. This wire is used in electrical installations of buildings, as well as in wiring of devices and switchboards.

Construction and properties

The wire is characterized by a flexible construction with a multi-strand core (class 5), which facilitates installation and routing even in difficult conditions. The insulation made of halogen-free EI5 compound provides not only safety but also resistance to UV radiation and corrosion. Thanks to this, the wire retains its properties for a long time, guaranteeing reliable operation of the installation. The rated voltage U0/U is 450/750V, which makes it a universal solution for many applications. The outer diameter ranges from 3.9 - 4.9 mm.

Applications and benefits

The H07Z-K wire is ideal for applications requiring a high level of fire safety. It can be used on and under plaster, in closed cable ducts, and as wiring inside devices and switchboards. Its halogen-free insulation meets the standards of DIN VDE 0285-525-3-41 / DIN EN 50525-3-41, which guarantees the limitation of smoke and corrosive gas emissions in the event of a fire. Additionally, this wire is characterized by good resistance to mechanical and chemical factors, which ensures its durability and reliability. The conductor resistance complies with DIN VDE 0295 class 5. The operating temperature range is from -40°C to +90°C, which allows its use in various environmental conditions.
