Frequently Asked Questions

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

This cable is designed primarily for photovoltaic solar power installations. It is perfect for connecting solar panels to each other, as well as for wiring from the panels to the inverter or junction box, whether mounted on rooftops or in ground-mounted structures.

Can this cable be installed outdoors without additional protection?

Yes, perfectly. Thanks to its outer covering of cross-linked elastomer and its H1Z2Z2-K certification, it continuously resists direct solar radiation, rain, frost and wind, without needing to be inserted into corrugated pipes, although the use of conduits always provides extra order and mechanical protection.

What advantages does halogen-free insulation offer?

Halogen-free, low-smoke insulation prevents the release of toxic and acidic gases in the event of combustion or fire. This significantly increases the safety of people and connected equipment, complying with current fire safety regulations.

How do you identify the polarity when using this red cable?

The red color of the outer cover is standardized to quickly and visually identify the wiring corresponding to the positive pole (DC+) of the photovoltaic system, avoiding connection errors during assembly, along with black cables for the negative pole.
