The cable of the brand VDE-Kabel, type NYY-J 5X2,5 RE 50M, is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It is a copper earth cable with PVC insulation and a black outer sheath, suitable for a wide range of installation situations in electrical engineering due to its construction and materials used. The designation NYY-J indicates the specific construction: NYY refers to a cable with PVC insulation and PVC outer sheath, while the letter J indicates the inclusion of a green-yellow protective conductor. The specification 5X2,5 describes the number of conductors (five) and the cross-section per conductor (2.5 mm²). The abbreviation RE denotes a round single-strand copper conductor manufactured according to VDE 0295. The delivery length is 50 meters, with the cable supplied as a coil.

Applications

The cable is designed for use in various environments, including outdoor areas, underground installations, indoor spaces, and cable ducts. It is particularly suitable for applications requiring high mechanical strength and resistance to environmental influences. Installation in the ground is possible due to the robust PVC sheathing and flame-retardant properties. Applications range from supplying lighting systems and electrical devices to control lines in industrial plants.

Functions and Equipment in Detail

The conductor is made of bare copper, manufactured according to VDE 0295, and is in the RE (round single-strand) configuration. This ensures high mechanical stability and low elongation during installation. The conductors are insulated with PVC, with conductor identification according to VDE 0293-308. For five conductors, identification by color and number is specified according to VDE standards, including the green-yellow protective conductor (J). A filler layer ensures even distribution of the conductors within the cable cross-section and supports mechanical stability. The outer sheath is made of black PVC, providing high resistance to UV radiation and atmospheric influences.

Technology Explained Simply

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 serves quality assurance 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 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 lines and 12 times for multi-conductor lines, influencing flexibility during installation. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures the cable does not propagate live flame during fire exposure, which is important for safety in buildings and installations.

Compatibility and Accessories

The cable is designed for use with standard sockets, switches, distributors, and other electrical components rated for a nominal voltage of 0.6/1 kV. Use with other cable types is only possible if electrical and mechanical requirements are compatible.

Installation and Mounting

Installation is carried out by fixed installation, with laying possible in the ground, in cable ducts, or indoors. Laying should be done while observing the specified bending radii to avoid damage. Temperature conditions during and after laying must be observed to ensure functionality and service life of the cable. Connection of the conductors is made using suitable connection techniques, such as cable lugs or terminals, designed for the respective cross-section.

Advantages in Operation

The cable offers high mechanical and thermal load capacity, enabling long service life and low maintenance frequency. The flame-retardant design increases operational safety, especially in enclosed spaces. The use of PVC as insulation and outer sheath material provides high resistance to environmental influences, including moisture and UV radiation. The integrated green-yellow protective conductor (J) meets electrical safety requirements and enables proper earthing of devices and installations.
