The product is an aluminium earthing cable of type designation NAYY-O 1X120 QMM, manufactured by Faber Kabel. It is an energy and control cable intended for use outdoors, in the ground, in power plants, industrial and switchgear installations, in water, in dry and damp indoor areas, in cable ducts, and in local networks, provided no mechanical damage is expected. The cable is designed without a protective conductor, as indicated by the "O" marking in the type designation. The conductor is made of aluminium and complies with standard VDE 0295. The construction may be round single-strand (RE), sector-shaped single-strand (SE), or sector-shaped multi-strand (SM). The core insulation is made of PVC, and core identification follows VDE 0293-308. A filler layer ensures internal stability of the cable, and the outer sheath is made of black PVC.

Applications
This cable is suitable for various applications in the field of energy and control technology. It can be laid in the ground, for example in local networks or for supplying industrial facilities. It is also suitable for use in water, such as in shoreline areas or hydroelectric plants. In indoor environments, regardless of humidity, as well as in cable ducts, it can be used. Its application is particularly recommended where no mechanical loads or damages are expected, as the cable is not designed for high mechanical stress.

Functions and Features in Detail
The aluminium conductor provides a conductive connection and is available in various configurations, where the shape (round, sector-shaped) influences installation and space requirements. The PVC insulation of the core ensures electrical separation and protects against short circuits. Core identification according to VDE 0293-308 enables unambiguous identification of individual cores. The filler layer ensures even distribution of cores within the cable cross-section and prevents displacement. The black PVC outer sheath provides protection against external influences such as moisture, UV radiation, and limited mechanical stress.

Technical Explanation
The rated voltage is 0.6/1 kV, meaning the cable is designed for operating voltages up to 1 kV. The test voltage of 4 kV is used for quality testing and ensures the cable remains stable even under increased voltage. The maximum operating temperature is +70 °C, indicating the thermal load capacity of the cable. During installation, temperatures from -5 °C to +50 °C are permissible; after installation, the cable can withstand temperatures from -30 °C to +70 °C. The bending radius is 12 times the cable diameter, which must be considered during installation to avoid damage. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), means that the cable does not produce flames or flame propagation during a fire test, enhancing safety in use.

Compatibility and Accessories
The cable is suitable for use in existing or newly constructed electrical installations, particularly in areas where aluminium conductors are specified. It can be used in combination with other cables of the NAYY type, especially those with a protective conductor (J) or different cross-sections, provided technical requirements are met. Use requires compliance with applicable standards and regulations, especially regarding installation and securing.

Installation and Mounting
Installation involves laying the cable in the ground, in cable ducts, or indoors. Required bending radii and temperature limits must be observed. Laying in the ground requires sufficient depth and protective measures against mechanical damage, such as protective conduits if necessary. Conductor connections must be made using suitable connection accessories designed for aluminium conductors. Installation must comply with applicable regulations and standards.

Operational Advantages
The cable offers high electrical conductivity due to the aluminium conductor and is suitable for use in various environments. The PVC insulation and outer sheath provide good resistance to moisture and environmental influences. Flame retardancy increases operational safety. The absence of a protective conductor reduces cross-section and can offer advantages in terms of space and weight for certain applications. Adhering to temperature and bending radius specifications ensures long service life and reliable operation.
