The copper earth cable NYY-J 5X4 RE 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 suitable for applications requiring a robust and long-lasting connection, particularly in industrial electrical engineering, construction, or for supplying outdoor installations. The cable features a bare copper conductor manufactured according to VDE 0295 and is configured in the round single-strand (RE) design. This conductor construction ensures high mechanical stability and low elongation, which is particularly advantageous for long installation runs.

Applications
This cable is suitable for use in various environments, including underground installation, outdoor areas, and indoor spaces. It can be installed in cable ducts, making it flexible for use in buildings, industrial facilities, or road and landscape construction. Outdoor use is possible due to the black-colored PVC outer sheath and flame-retardant properties. The protection rating of the cable allows installation under ground and outdoor conditions, provided environmental conditions such as temperature and humidity remain within specified limits.

Functions and Equipment in Detail
The cable consists of five conductors, each with a cross-section of 4 mm², one of which is configured as a protective earth conductor (J). Conductor identification follows VDE 0293-308, with standardized color coding and marking for up to five conductors. The conductors are insulated with PVC, providing good electrical insulation and mechanical stability. A filler layer ensures even distribution of the conductors within the cable cross-section and prevents displacement of individual conductors. The outer sheath is made of black PVC, resistant to UV radiation and mechanical stress.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for voltages up to 1 kV with an operating voltage of 0.6 kV. The test voltage of 4 kV is used for quality control and ensures the cable shows no insulation defects even under increased electrical stress. The operating temperature is limited to a maximum of +70 °C, with installation permitted at temperatures from -5 °C to +70 °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-conductor cables and 12 times for multi-conductor cables, requiring careful bending to avoid mechanical damage. The flame retardancy complies with VDE 0472 Part 804, Test Method B, equivalent to IEC 332-1, ensuring limited flame spread in case of fire.

Compatibility and Accessories
The cable is suitable for use with standard cable connectors, sockets, switches, and other electrical components designed for a rated voltage of 0.6/1 kV. It can be installed in cable ducts, underground, or outdoors, provided installation conditions comply with technical specifications.

Installation and Mounting
Installation requires adherence to specified bending radii to avoid mechanical damage to the conductors. Installation should occur at temperatures between -5 °C and +70 °C. After installation, the cable must rest for at least 24 hours to ensure complete stabilization of the PVC sheath. Connection to other components is made using appropriate cable lugs, plug connectors, or cable glands designed for the respective voltage and cross-section.

Operational Advantages
The cable offers high mechanical strength and resistance to external influences such as moisture, UV radiation, and mechanical stress. The use of copper as the conductor material ensures high electrical conductivity and low resistance losses. The flame-retardant design increases safety in case of fire. The black-colored PVC outer sheath protects the cable from external influences and allows easy identification in the installation area.
