VDE-Kabel 240517 NYY-J 3x2.5 mm² RE 50 m-ring Eca PVC-insulated earth cable content_copy

The copper earth cable NYY-J 3X2.5 RE 50M from VDE-Kabel is a fixed installation power and control cable designed for use outdoors, in the ground, indoors, and in cable ducts. It is particularly suitable for applications requiring high mechanical and chemical resistance as well as secure power supply. The cable features a protective conductor (designation J), which enhances electrical safety, and is supplied in a length of 50 meters as a coil. The conductors are made of bare copper, manufactured according to VDE 0295, with RE indicating round single-strand. The cores are insulated with PVC, and core identification follows VDE 0293-308. The outer sheath is also made of black PVC, providing high resistance to UV radiation and atmospheric influences.

Applications
This cable is suitable for use in various environments, including outdoor areas, underground installations, indoor spaces, and cable ducts. It is commonly used in building electrotechnics, industry, and plant construction, where reliable and durable connections are required. Underground installation is possible due to the robust PVC sheathing and mechanical strength, without requiring additional protective measures. Applications range from powering outdoor lighting to industrial control lines and energy distribution in residential and commercial buildings.

Functions and Equipment in Detail
The cable comprises three cores, each with a cross-section of 2.5 mm², one of which is a green-yellow protective conductor. The conductors are round and single-strand (RE), ensuring high mechanical strength and minimal elongation during installation. The PVC insulation of the cores provides good electrical insulation and chemical resistance. The filler layer ensures even distribution of the cores within the cable cross-section and prevents core displacement. The black PVC outer sheath offers additional protection against mechanical damage, moisture, and UV radiation.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, meaning it is designed for voltages up to 1 kV with a test voltage of 4 kV. The maximum operating temperature is +70 °C, with installation possible at temperatures from -5 °C. After installation, the cable 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 cables, enabling flexible installation. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning the cable does not produce flames or flame propagation during a fire test.

Compatibility and Accessories
The cable is suitable for use with standard sockets, switches, distributors, and other electrical components rated for 0.6/1 kV. It can be used in combination with cable protection conduits, cable ducts, and other installation aids to enhance mechanical safety. The use of cable ties or mounting elements is recommended to secure the cable during installation and operation. Connections are made using appropriate cable lugs, cable terminals, or other connection means designed for a cross-section of 2.5 mm².

Installation and Mounting
Installation is performed by fixed mounting, with options for underground, in cable ducts, or indoors. Underground installation requires a minimum depth that varies according to local regulations and environmental conditions. Bending radii must be observed to avoid damaging the conductors. Installation should be carried out by qualified professionals to ensure electrical safety.

Operational Advantages
The cable offers high mechanical and chemical resistance, enabling long service life and low maintenance costs. The PVC insulation and outer sheath protect the cable against moisture, UV radiation, and mechanical stress. Flame retardancy according to VDE 0472 Part 804 test method B increases safety in case of fire. The inclusion of a protective conductor (J) enhances electrical safety and meets requirements for protective measures in electrical installations. The cable length of 50 meters allows efficient planning and installation without additional connections.
