TXXI (RZ1-K)

Power cable 0,6/1 kV with Cu conductors, XLPE insulated and HFFR sheathed

TXXI (RZ1-K)

APPLICATION

This is a flexible power and control cable designed for indoor fixed applications with a voltage rating is 600/1000V. It is manufactured with Class 5 flexible copper conductors to facilitate installations with sinuous courses, including in underground supply networks for outdoor lighting. This cable is not suitable for direct burial.
The Low Smoke Zero Halogen (LSZH) Polyolefin oversheath creates a high safety cable that will not emit toxic fumes and smoke in the event of fire, making it appropriate for installations such as buildings and public areas where there is a high concentration of people or valuable equipment.
