Halogen-Free Electrical Cable 4 mm² Black 20 m: Safety and Maximum Conductivity

The Halogen-Free Electrical Cable 4 mm² Black 20 m (H07Z1-K) with reference B25114905 is the ultimate solution for professional and domestic electrical installations that demand the highest standards of safety, flexibility, and durability. Designed for superior performance, this flexible black cable is ideal for wiring in electrical panels, recessed or surface-mounted conduits, and cable trays. Its halogen-free composition ensures that, in the event of a fire, it does not emit toxic or corrosive gases and exhibits low smoke opacity, protecting both people and sensitive electronic equipment.

Main Advantages of Flexible Thread H07Z1-K

This 4 mm² cable stands out for its excellent handling thanks to its flexible electrolytic copper construction with thermoplastic polyolefin insulation. Its 4 mm² cross-section is the perfect choice for circuits that handle higher currents, such as general-purpose sockets, washing machines, dishwashers, or dryers. The outer sheath facilitates optimal sliding through corrugated conduits, significantly reducing installation time and effort during wiring. Furthermore, its fire resistance and ability to withstand high operating temperatures ensure a long service life without insulation degradation.

Frequently Asked Questions

What type of installations is this 4 mm² cable recommended for?

It is especially recommended for indoor installations in homes, commercial premises, and offices. It is ideal for wiring power circuits or sockets that require a cross-section of 4 mm² according to current regulations.

What does it mean for it to be a halogen-free cable?

This means its casing does not contain halogen elements such as fluorine, chlorine, bromine, or iodine. In the event of a fire, this prevents the formation of corrosive acids that damage metals and electronic circuits, and drastically reduces toxic smoke, facilitating evacuation.

Is it easy to pass through the installation pipes?

Yes, being a flexible class 5 wire with a slippery outer finish, it bends and slides very easily inside tubes and conduits, even when there are already other cables inside.
