The cable of the brand Faber Kabel, type NYY-J 5G95QMM, is a fixed-installed power and control cable designed for use outdoors, in the ground, indoors, as well as in cable ducts. It is a copper earth cable with PVC insulation and a black PVC outer sheath, designed for high mechanical and electrical load capacity due to its construction and materials used. The designation NYY-J indicates a cable with a green-yellow protective conductor, which is essential for safe operation in electrical installations. The specification 5G95QMM describes the configuration with five conductors, each having a cross-section of 95 mm² and being round multi-strand (RM). The designation QMM refers to the specific conductor configuration used in the product designation.

Applications
This cable is designed for use in various environments, including installation in the ground, outdoor areas, indoor spaces, and cable ducts. It is particularly suitable for applications requiring high mechanical stability and resistance to environmental influences. Installation in the ground requires high resistance to moisture, soil weathering, and mechanical stress, which is ensured by the PVC insulation and robust outer sheath. Fixed installation indoors, for example in industrial plants or buildings, benefits from the cable’s high electrical conductivity and thermal stability.

Functions and Equipment in Detail
The conductor is made of bare copper manufactured according to VDE 0295. The round multi-strand (RM) design ensures high flexibility and bending strength, which is particularly advantageous during installation in narrow or curved ducts. The conductor insulation is made of PVC, providing good electrical insulation and mechanical strength. The conductor identification follows VDE 0293-308, with standardized color coding and marking for up to five conductors. The green-yellow protective conductor (J) is an integral part of the cable and serves electrical safety. The filler layer ensures even distribution of the conductors within the cable cross-section and prevents relative movement between conductors. The outer sheath is made of black PVC, which is UV-resistant and resistant to atmospheric influences.

Technology Explained Simply
The rated voltage of 0.6/1 kV defines the maximum operating voltage range within which the cable can be safely operated. The test voltage of 4 kV is used for quality testing and ensures that the cable does not experience breakdowns even under increased electrical stress. The maximum operating temperature is +70 °C, meaning the cable remains stable even at elevated ambient temperatures or under load conditions. During installation, the temperature must not fall below -5 °C; after installation, operation is possible from -30 °C. The bending radius is 15 times the cable diameter for single-conductor cables and 12 times for multi-conductor cables, enabling installation in tight radii. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures that the cable does not ignite easily in case of fire and does not propagate flames.

Compatibility and Accessories
The cable is designed for use in electrical installations executed according to applicable standards and regulations (e.g., VDE 0295, VDE 0293-308). It can be combined with other cables and installation components that also comply with standards for earth and control cables. Use in cable ducts requires appropriate duct sizing to maintain the required bending radii. Installation in the ground requires sufficient depth and protective measures to avoid mechanical damage.

Installation and Mounting
Installation is performed by fixed mounting, with required bending radii strictly observed to ensure the mechanical integrity of the cable. Installation in the ground requires sufficient depth and possibly additional protective measures such as protective sleeves or conduit pipes. Installation indoors or in cable ducts is typically done by pulling or laying, with electrical connections at the ends made according to VDE regulations. The conductors are connected using suitable terminals, screw terminals, or crimp connections, depending on the application.

Advantages in Operation
The cable offers high electrical conductivity due to the copper conductor, resulting in low voltage drops. The PVC insulation and outer sheath provide high mechanical and chemical resistance. Flame retardancy increases safety in case of fire. The use of a green-yellow protective conductor (J) ensures safe operation and meets electrical safety requirements. The high flexibility due to the multi-strand design facilitates installation and reduces the risk of cracks or breaks during bending.
