The copper earth cable NYY-J 10X1.5 RE from Helukabel is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It is suitable for applications requiring a robust and long-lasting connection, particularly in areas with increased mechanical and environmental influences. The cable features a PVC outer sheath in black, providing high mechanical strength and weather resistance. The conductors are insulated with PVC insulation and comply with the designation according to VDE 0293-308, where the designation J indicates the inclusion of a green-yellow protective conductor. The conductors are made of bare copper, manufactured according to VDE 0295, and are configured as round single-strand (RE), ensuring high mechanical stability and low elongation during installation.

Applications
This cable is suitable for use in various environments, including underground installation, outdoor areas, indoor spaces, and cable ducts. It is commonly used in industry, construction, and energy supply, where a reliable and durable electrical connection is required. Installation must consider the specified temperature ranges, which range from -5 °C to +70 °C during installation, and from -30 °C to +70 °C after installation. The maximum operating temperature is +70 °C, ensuring suitability for normal operating conditions.

Functions and Equipment in Detail
The cable features 10 conductors, each with a cross-section of 1.5 mm², one of which is configured as a green-yellow protective conductor. The conductors are separated by a filler sheath, ensuring even distribution and mechanical stability. The round single-strand configuration (RE) of the conductors provides high strength and low elongation, which is particularly advantageous for long installation runs. The PVC insulation offers good electrical insulation and resistance to moisture and chemical influences.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, making it suitable for use in low-voltage installations. The test voltage of 4 kV ensures the cable remains stable even under increased voltage loads. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures the cable does not act as a flame spreader in case of fire, thus minimizing fire load. 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.

Compatibility and Accessories
The cable is designed for use in existing or newly constructed electrical installations requiring a rated voltage of 0.6/1 kV. It is compatible with standard cable connectors, cable lugs, and other connection elements designed for PVC-insulated cables. Use in cable ducts or underground installation may require additional protective measures, such as protective conduits, depending on environmental conditions.

Installation and Mounting
Installation must comply with the specified bending radii and temperature ranges. When installing underground, sufficient depth and protection against mechanical stress must be ensured. Installation in cable ducts requires proper securing to prevent unwanted movement or stress. Connections between conductors must be made using appropriate connection elements, ensuring electrical continuity and mechanical strength.

Operational Advantages
The cable offers high mechanical strength, weather resistance, and electrical reliability. The PVC insulation and outer sheath ensure long service life and low maintenance. Compliance with standards VDE 0295 and VDE 0472 Part 804 guarantees safety and reliability in operation. The use of a green-yellow protective conductor (J) meets the requirements for protective measures in electrical installations.
