The NAYY-J 1X240 RM var. from Faber Kabel is a low-voltage earth cable with an aluminium conductor, designed for use outdoors, in soil, in water, as well as in dry and damp indoor environments. It is particularly suitable for power plants, industrial and switching installations, cable ducts, and local networks, provided no mechanical damage is expected. The cable features a protective conductor (designation J) and is therefore suitable for use in electrical installations with protective conductor systems. The outer sheath is made of black PVC, ensuring high resistance to environmental influences.

Applications
This cable is intended for various applications in the fields of energy and control technology. It can be installed in soil, is suitable for use in water, and is also appropriate for indoor spaces regardless of humidity levels. Its use in cable ducts and local networks is also specified, provided no mechanical stresses occur. The combination of an aluminium conductor and PVC insulation makes it especially suitable for installations in industrial and energy sectors, where high electrical conductivity and mechanical stability are required.

Functions and Features in Detail
The conductor is made of aluminium in accordance with VDE 0295 and is either round single-strand (RE), sector-shaped single-strand (SE), or sector-shaped multi-strand (SM). The core insulation is made of PVC, with core identification following VDE 0293-308. A filler layer ensures even distribution of the cores within the cable cross-section. The protective conductor (J) is integrated, enabling compliance with protective measures in electrical installations. The black PVC outer sheath provides protection against external influences and is suitable for outdoor use.

Technical Details Explained
The rated voltage is 0.6/1 kV, enabling use in low-voltage installations. The test voltage of 4 kV ensures the cable’s electrical strength. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +50 °C during installation and from -30 °C to +70 °C after installation. The bending radius is 12 times the cable diameter, allowing flexible installation. Flame retardancy complies with VDE 0472 T. 804, test type B (equivalent to IEC 332-1), meaning the cable does not propagate live flame during a fire test and thus presents a low fire hazard.

Compatibility and Accessories
The cable is designed for use in electrical installations requiring a rated voltage of 0.6/1 kV. It is equipped with a protective conductor, enabling use in protective conductor systems. Installation can take place in soil, water, cable ducts, or indoor spaces, with mechanical stress being limited.

Installation and Mounting
Installation must consider the specified temperature ranges: between -5 °C and +50 °C during installation, and between -30 °C and +70 °C after installation. The bending radius of 12 times the cable diameter must be observed to avoid damage. Installation is carried out in soil, water, cable ducts, or indoor spaces, while mechanical damage must be avoided.

Operational Advantages
The cable offers high electrical conductivity due to the aluminium conductor and good mechanical stability due to the PVC outer sheath. Flame retardancy according to VDE 0472 T. 804, test type B, reduces fire hazard. Installation in soil and water is possible, increasing installation flexibility. The integrated protective conductor (J) enables compliance with safety regulations in electrical installations. Temperature resistance from -30 °C to +70 °C after installation ensures stable operation under various environmental conditions.
