The 10 mm² Halogen-Free Electrical Cable, Grey, 50 m reel (H07Z1-K), is the ultimate professional solution for low-voltage electrical installations demanding the highest levels of safety, efficiency, and regulatory compliance. Specifically designed for conduit installations, both recessed and surface-mounted, as well as within electrical panels and switchgear, this flexible cable offers exceptional performance in residential, commercial, and industrial environments.

Thanks to its advanced halogen-free technology, this cable does not propagate fire, emits virtually no smoke, and is completely free of toxic or corrosive gases in the event of a fire. This characteristic makes it an essential requirement for use in public spaces such as hospitals, schools, shopping centers, and office buildings, protecting both people and sensitive electronic equipment.

Its 10 mm² cross-section ensures excellent current-carrying capacity with minimal voltage drop losses, optimizing the installation's energy efficiency. The high-quality, special PVC insulation provides excellent mechanical resistance to abrasion and wear during installation and routing inside corrugated conduits.

The compact 50-meter roll format facilitates storage, transport, and handling on-site, allowing for precise cuts according to project requirements. Its gray color simplifies circuit identification and organization within the electrical installation, complying with current regulations.

Frequently Asked Questions

What type of installations is this 10 mm² cable recommended for?

This cable is especially suitable for low voltage indoor installations, wiring of electrical panels, individual branch circuits and power circuits or service connections that require a cross-section of 10 mm² and strict compliance with fire safety regulations in public places.

What are the advantages of it being a halogen-free cable?

The main advantage is safety. In case of fire, halogen-free cables do not emit toxic gases or corrosive acids that could damage the respiratory system or destroy delicate electronic equipment, and they also generate very little smoke, which greatly improves visibility for a possible evacuation.

Can it be installed directly buried in the wall without a protective tube?

No. This cable is designed to be installed inside protective conduits, either embedded or surface-mounted, or inside protective trunking and electrical panels. It must not be installed directly buried or outdoors without the protection of a suitable conduit.

Is it easy to pass through the inside of corrugated pipes?

Yes, thanks to its flexible Class 5 copper conductor and the slip-resistant finish of its outer insulation, this wire offers excellent flexibility and slippage, greatly facilitating the insertion of cables in new installations or renovations.
