The cable of the brand VDE-Kabel, type NYY-J 5 X 1.5 RE, is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, as well as in cable ducts. It is a copper earth cable with PVC insulation and a black outer sheath, suitable for supplying electrical installations in various environments. The designation NYY-J indicates a cable with PVC insulation and PVC outer sheath, where the letter J signifies the presence of a green-yellow protective conductor. The specification 5 X 1.5 describes the configuration with five conductors, each having a cross-section of 1.5 mm². The designation RE stands for a round single-strand copper conductor, manufactured according to VDE 0295, ensuring stable and durable line safety.

Applications
This cable is suitable for a wide range of applications in the field of electrical installation, particularly where fixed installation in the ground or outdoors is required. It can also be installed indoors or in cable ducts, where the PVC insulation and outer sheath provide high mechanical and chemical resistance. Use in the ground requires a cable type protected against moisture, mechanical stress, and environmental influences — here, the NYY-J 5 X 1.5 RE meets the necessary requirements.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, where the designation RE refers to a round single-strand conductor. This type is especially suitable for fixed installations, as it offers high mechanical strength and low elongation. 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 conductor serving as the protective conductor. A filler layer ensures even distribution of the conductors within the cable cross-section, providing a stable structure and even load distribution. The outer sheath is also made of PVC and is black, offering high resistance to UV radiation and mechanical stress.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, meaning it is suitable for applications with an operating voltage up to 1 kV. The test voltage of 4 kV serves as a safety margin and ensures the cable remains stable even under increased electrical stress. The operating temperature is limited to a maximum of +70 °C, defining the thermal load capacity of the cable. During installation, the temperature must be between -5 °C and +70 °C; after installation, a temperature range of -30 °C to +70 °C is permissible. The bending radius is 15 times the cable diameter for single-conductor cables and 12 times for multi-conductor cables, 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), ensures that the cable does not act as a source of flame spread during a fire and limits flame propagation.

Compatibility and Accessories
The cable is designed for use in electrical installations requiring fixed installation. It is compatible with standard installation techniques and materials, such as cable ducts, earth pipes, or other installation aids. Compatibility information refers exclusively to the technical properties of the cable itself.

Installation and Mounting
Installation of the cable requires adherence to the specified temperature and bending radius requirements. When laying in the ground, it must be ensured that the cable is not mechanically damaged, for which reason a sufficient protective layer or protective pipe is recommended. Installation indoors or in cable ducts is carried out in accordance with applicable electrical installation regulations.

Advantages in Operation
The cable offers high mechanical and thermal stability, ensuring long service life and reliable performance. The PVC insulation and outer sheath provide high resistance to moisture, UV radiation, and chemical influences. Flame retardancy according to VDE 0472 Part 804, test method B, increases operational safety. The use of a green-yellow protective conductor (J) meets requirements for safe earthing. The combination of solid conductor cross-section and stable insulation makes the cable a reliable choice for power and control lines in various applications.
