VDE-Kabel 246571 NYY-J 5x2.5 mm² RE PVC-insulated earth cable drum content_copy

The cable of the brand VDE-Kabel, type NYY-J 5X2,5 RE TR, 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 is equipped with a green-yellow protective conductor, ensuring compliance with VDE standards for electrical safety. The designation NYY-J indicates a cable with PVC insulation of the conductors and a PVC outer sheath, where the letter J signifies the presence of a protective conductor. The specification 5X2,5 describes the configuration with five conductors, each having a cross-section of 2.5 mm². The designation RE stands for a round single-strand copper conductor, manufactured according to VDE 0295, ensuring a stable and conductive connection.

Applications
This cable is suitable for a wide range of applications, particularly in building and infrastructure technology. It is frequently used in outdoor installations and underground cabling, such as supplying garden sheds, outdoor lighting, electrical systems in parks, or wiring industrial facilities. Installation in cable ducts enables orderly and protective routing of cables in indoor environments. Applications also include supplying machines, drives, and electrical devices requiring safe and durable power supply.

Functions and Features in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, ensuring high electrical conductivity and mechanical stability. The conductors are insulated with PVC, providing good insulation performance and chemical resistance. Conductor identification follows VDE 0293-308, with standardized color coding for up to five conductors. The green-yellow protective conductor is clearly identifiable and meets the requirements for protective conductors in electrical installations. A filler layer ensures even distribution of the conductors within the cable cross-section and prevents uneven loading. The outer sheath is made of black PVC, offering high mechanical strength, UV resistance, and protection against environmental influences.

Technical Explanation
The rated voltage of 0.6/1 kV makes the cable suitable for use in low-voltage installations, as commonly found in residential and industrial applications. The test voltage of 4 kV serves safety testing and ensures insulation strength under load. The maximum operating temperature is +70 °C, describing the thermal load capacity of the cable under normal operating conditions. For installation, a minimum temperature of -5 °C is required; after installation, the cable can be operated at -30 °C, enabling broad applicability 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 without damaging the cable. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), means the cable is only limitedly flammable and does not propagate live flame, enhancing safety in confined spaces.

Compatibility and Accessories
The cable is suitable for use with standard cable lugs, cable glands, and other connection elements designed for PVC insulation and copper conductors. It can be used in combination with earth cable shafts, cable ducts, and other installation aids to ensure proper and safe installation. Use in underground installations typically requires an additional mechanical protection layer, such as a protective sleeve or conduit, to protect the cable from mechanical damage. Compatibility with other cable types in the NYY series is ensured, provided technical specifications match.

Installation and Mounting
Installation is performed by fixed installation, with the cable laid in the ground, in cable ducts, or indoors. Underground installation requires sufficient depth and possibly an additional mechanical protection layer. Bending radii must be observed to avoid damaging the conductors. Connections of the conductors are made using appropriate cable lugs or other connection elements designed for a cross-section of 2.5 mm². Electrical connections must be carried out in accordance with VDE 0100-510 and other applicable standards to ensure safety.

Operational Advantages
The cable offers high mechanical strength, chemical resistance, and thermal load capacity. The PVC insulation ensures reliable electrical insulation, while the black-colored outer sheath is UV-resistant and remains stable over time even in outdoor environments. The flame-retardant design enhances safety in confined spaces and fire-prone areas. The use of a green-yellow protective conductor meets electrical safety requirements and enables safe grounding. The combination of copper conductors and PVC insulation ensures high conductivity and long service life.
