The cable of the brand Faber Kabel, type NYY-J 40X1,5 RE, 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 the transmission of electrical energy and control signals in industrial, commercial, and municipal installations. The designation NYY-J indicates a cable with PVC insulation of the conductors and a PVC outer sheath, where the addition J denotes the inclusion of a green-yellow protective conductor. The specification 40X1,5 RE means that the cable has 40 conductors, each with a cross-section of 1.5 mm², with the conductors being round single-strand (RE). This construction is particularly suitable for applications requiring high mechanical stability and low elongation.

Applications

The cable is intended for use in underground installations, outdoor environments, and indoor spaces. It is suitable for installation in cable ducts and is designed for fixed installations. Use outdoors requires high resistance to environmental influences such as moisture, UV radiation, and mechanical stress, which is ensured by the PVC insulation and the black-colored outer sheath. The cable construction is suitable for use in buildings, industrial plants, street lighting systems, and other infrastructure projects.

Functions and Equipment in Detail

The conductor is made of bare copper, manufactured according to VDE 0295, and is constructed as round single-strand (RE). This design offers high mechanical strength and low elongation, which is particularly advantageous for long installation runs and when installing in tight bends. The conductors are insulated with PVC, with conductor identification according to VDE 0293-308. For up to five conductors, identification is done by color, with the green-yellow protective conductor (J) explicitly included. From six conductors onwards, identification is done by black conductors with white numbers. A filler layer ensures even distribution of the conductors in the cable cross-section and prevents relative movement between the conductors.

Technology Explained Simply

The rated voltage is 0.6/1 kV, meaning the cable is designed for operating voltages up to 1 kV, with a test voltage of 4 kV. This provides sufficient safety margin for electrical insulation. The maximum operating temperature is +70 °C, and installation is permitted at temperatures from -5 °C to +70 °C. After installation, the cable can be operated at temperatures from -30 °C to +70 °C, enabling broad application in various climate zones. The bending radius is 15 times the cable diameter for single-conductor cables and 12 times for multi-conductor cables, allowing flexible installation even in tight radii. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning the cable does not drip flaming particles and does not propagate flame during a flame test.

Compatibility and Accessories

The cable is suitable for use in existing and new installations requiring fixed installation of power and control lines. It is compatible with standard cable connectors, cable lugs, and other connection elements designed for PVC-insulated cables. Use in underground installations typically requires an additional protective sleeve or installation in pipes to prevent mechanical damage. The cable construction is suitable for use in cable ducts and indoor spaces, where the PVC insulation and outer sheath provide sufficient mechanical and electrical insulation.

Installation and Mounting

Installation is carried out by fixed installation, with installation temperatures ranging from -5 °C to +70 °C. Bending radii depend on the conductor construction: for round single-strand conductors, the bending radius is 15 times the cable diameter; for multi-conductor cables, it is 12 times. Installation is typically done from reels, with cable length varying by supplier. Cable ends are connected using suitable cable lugs or connection terminals designed for a cross-section of 1.5 mm². Installation requires compliance with applicable electrical regulations, particularly VDE rules.

Operational Advantages

The cable offers high mechanical stability and sufficient electrical insulation, ensuring long service life and safe operation. The PVC insulation provides good protection against moisture and chemical influences, making the cable suitable for use in damp environments. Flame retardancy according to VDE 0472 Part 804 (test method B) increases operational safety, especially in enclosed spaces. The inclusion of the green-yellow protective conductor (J) meets electrical safety requirements and enables proper grounding of the installation.
