The copper earth cable NYY-J 10X2.5 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, such as in industry, construction, or outdoor facility supply. The cable features a black-coloured PVC outer sheath that resists mechanical stress and environmental influences such as moisture or UV radiation. The conductors are insulated with PVC and marked according to VDE 0293-308, with the designation J indicating the inclusion of a green-yellow protective conductor.

Applications
This cable is designed for use in various environments, including underground installation, outdoor areas, indoor spaces, and cable ducts. It is commonly used in electrical installations, machine supply, building automation, or connecting electrical devices. Installation must consider the specified temperature ranges: -5 °C to +70 °C during installation and -30 °C to +7ron °C after installation.

Functions and Features in Detail
The conductors are made of bare copper and comply with the standard VDE 0295. The designation RE stands for round single-strand, ensuring high mechanical stability and low elongation during installation. The conductors are insulated with PVC, providing good insulation performance and chemical resistance. The filler layer ensures even distribution of the conductors within the cable cross-section and prevents displacement. The black-coloured PVC outer sheath protects the cable from external influences and is suitable for outdoor use.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for operation at 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 maximum operating temperature is +70 °C, ensuring suitability for normal operating conditions. The bending radius is 15 times the cable diameter for single-core construction and 12 times for multi-core construction, allowing installation in tight radii. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures limited flame spread in case of fire.

Compatibility and Accessories
The cable is designed for use in electrical installations complying with standards VDE 0295 and VDE 0293-308. It can be combined with other cables of type NYY-J, particularly in installations requiring a protective conductor. Use in cable ducts or underground installation requires no additional protective measures, as the cable is already designed for these conditions.

Installation and Mounting
Installation must comply with the specified temperature ranges. During installation, sufficient bending radius must be maintained to avoid cable damage. Underground installation requires adequate depth and possibly additional protective measures such as protective conduits if environmental conditions are particularly harsh. Connections are made using suitable cable lugs or cable glands designed for the respective cross-sectional size.

Operational Advantages
The cable offers high mechanical strength and is resistant to environmental influences such as moisture, UV radiation, and mechanical stress. The PVC insulation ensures reliable electrical insulation, and flame retardancy increases operational safety. The use of a green-yellow protective conductor (J) meets electrical safety requirements in electrical installations.
