Optimize your electrical installations with the 2.5 mm² Halogen-Free Electrical Cable in Green/Yellow (25-meter reel) . This conductor wire is designed to offer maximum safety, flexibility, and performance in both professional construction projects and home renovations. This single-core H07Z1-K cable is the essential solution for ensuring efficient current conduction while complying with the strictest fire safety regulations.

Advanced safety and halogen-free technology

When working with electrical installations, safety is paramount. This cable stands out for its halogen-free construction, meaning that in the event of a fire, it emits no toxic or corrosive gases and produces minimal smoke, facilitating evacuation and protecting surrounding electronic equipment. Its high-quality insulation, made from special thermoplastic compounds, ensures excellent resistance to wear and tear, making it ideal for installation in conduit in homes, offices, public spaces, and high-traffic buildings.

Maximum flexibility and ease of installation

Thanks to its Class 5 design with a flexible electrolytic copper core, the H07Z1-K wire allows for exceptionally easy handling during wiring. It slides smoothly through corrugated conduits and junction boxes, significantly reducing installation time and effort. Its 2.5 mm² cross-section is the ideal standard for supplying power to general-purpose circuits, household and general-purpose power outlets, and for earthing, clearly identified by its characteristic green and yellow color in accordance with current regulations.

Frequently Asked Questions

What type of circuits is this 2.5 mm² cable recommended for?

This section is especially suitable for general purpose circuits in homes and premises, such as standard power outlets, appliance power supplies and as a protective conductor or grounding (identified with the color green/yellow).

What advantages does a halogen-free cable offer compared to traditional PVC?

The main advantage lies in fire safety. Halogen-free cables do not propagate flames aggressively, do not emit corrosive gases that damage lungs or equipment, and produce very little smoke, meeting the standards required in public access facilities.

Is it easy to pass through existing pipes?

Yes, because it is a wire with a flexible class 5 conductor and has a sliding insulation, it offers great maneuverability that greatly facilitates pulling cables through corrugated pipes and narrow conduits.

Does it include the full 25-meter reel?

Yes, the product is supplied in roll or coil format with a total length of 25 meters, ready for use and dosing on site.
