Protective conductor

The cable NYY-J 24X1.5 RE from Faber Kabel is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It is used for transmitting electrical power and control signals in industrial, commercial, and municipal installations. The cable features a protective conductor (designation J), which, according to VDE 0293-308, ensures safe earthing of electrical installations. The designation RE indicates a round, single-strand copper conductor, manufactured in accordance with VDE 0295, offering high mechanical stability and minimal deformation during installation.

Applications
This cable is suitable for use in underground installations, for example, in supplying outdoor lighting, garden installations, industrial machinery, or in building electrical systems. It can also be installed indoors or in cable ducts where high mechanical and chemical resistance is required. Outdoor use is possible due to the PVC insulation and the black PVC outer sheath, as these materials are UV-resistant and withstand atmospheric influences.

Functions and Features in Detail
The conductor is made of bare copper, ensuring high electrical conductivity. The cores are insulated with PVC, providing good insulation performance and chemical resistance against moisture and common environmental substances. Core identification follows VDE 0293-308; for 24 cores, identification is done with black cores and white numerals. The filler layer ensures even distribution of cores within the cable cross-section and prevents individual conductors from shifting. The black PVC outer sheath protects the cable against mechanical stress, moisture, and external influences.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is suitable for applications with an operating voltage up to 1 kV. The test voltage of 4 kV is used for quality control and ensures insulation strength. The operating temperature is limited to a maximum of +70 °C, with the cable tolerating installation temperatures from -5 °C to +70 °C. After installation, it can be operated at temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core conductors, enabling flexible installation even in tight bends. The flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures the cable is either non-flammable or only limitedly flammable and does not propagate a live flame during a fire.

Compatibility and Accessories
The cable is suitable for use in existing or new electrical installations requiring fixed installation. It can be connected using standard cable lugs, cable glands, and other connection elements designed for PVC-insulated cables. Use in underground installations may require additional protective measures such as protective conduit pipes, depending on local regulations and environmental conditions.

Installation and Mounting
Installation typically involves pulling the cable into cable ducts, securing it to supports, or laying it directly in the ground. For underground installation, it is essential to ensure the cable is buried deep enough to avoid mechanical damage. Bending radii must be observed to maintain conductor integrity. Connections between cores are made using appropriate cable lugs or connectors, ensuring correct polarity and earthing.

Operational Advantages
The cable offers high mechanical strength, resistance to moisture and UV radiation, and is suitable for a wide range of applications. The PVC insulation ensures long service life and high safety. The integrated earthing conductor (J) enables safe and reliable earthing, which is crucial for the safety of the installation. Flame retardancy enhances fire safety in electrical systems.
