The copper earth cable NYY-J 4X16 RE from VDE-Kabel 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 reliable and durable power supply or control, particularly in industrial, commercial, or municipal facilities. The cable features a green-yellow protective conductor (J), ensuring compliance with VDE standards for electrical installations and enhancing operational safety.

Applications
This cable is suitable for use in underground installations, outdoor environments, and indoor spaces. It can be installed in cable ducts, making it versatile for use in building electrotechnics, machine supply, or infrastructure technology. Outdoor use requires high mechanical and chemical resistance, which is ensured by the PVC outer sheath and the cable’s construction.

Functions and Equipment in Detail
The cable consists of bare copper conductors manufactured according to VDE 0295. The conductors are round and single-strand (RE), providing high mechanical stability and minimal elongation during installation. The cores are insulated with PVC, ensuring good electrical insulation and chemical resistance. Core identification follows VDE 0293-308, with the green-yellow protective core (J) clearly identifiable. A filler layer ensures even distribution of cores within the cable cross-section, improving mechanical stability and installation properties. The outer sheath is made of black PVC, which is UV-resistant and resistant to atmospheric influences.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for operating voltages up to 1 kV. The test voltage of 4 kV serves quality control and ensures insulation strength. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +70 °C during installation. After installation, it can withstand temperatures from -30 °C to +70 °C, enabling broad application in various climate zones. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core cables, allowing flexible installation even in tight radii. Flame retardancy according to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), limits flame spread in case of fire.

Compatibility and Accessories
The cable is compatible with standard installation techniques and materials. It can be combined with other cables from the NYY series, especially in systems requiring underground or outdoor applications. The use of cable reels, typical for this product, facilitates installation and storage. The cable construction is compatible with common cable protection conduits, cable ducts, and connection elements designed for PVC insulation.

Installation and Mounting
Installation is performed by fixed laying, with required bending radii strictly observed to ensure mechanical integrity. Underground installation requires sufficient depth and protection against mechanical damage, such as using protective conduits. Outdoor or cable duct installation requires consideration of environmental conditions, particularly temperature and humidity limits. Electrical connections are made using suitable cable lugs or connectors designed for a cable cross-section of 16 mm².

Operational safety is ensured by the integrated green-yellow protective conductor (J) and the flame-retardant construction. The cable construction allows for long service life when installed and used correctly. Use in cable ducts or underground does not require additional protective measures, provided technical specifications are followed.

Advantages in Operation
The cable offers high mechanical strength, chemical resistance, and electrical reliability. The PVC insulation and black-colored outer sheath protect the cable against UV radiation, moisture, and atmospheric influences. The flame-retardant design reduces fire risk and improves building safety. The single-strand, round conductor construction (RE) ensures minimal elongation and high stability, simplifying installation and operation. The integrated protective conductor (J) meets VDE standard requirements and enhances safety in the electrical system.
