The cable NYY-J 3X6 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 used for transmitting electrical energy and control signals in industrial, commercial, and municipal installations. The cable features a black-coloured PVC outer sheath and is equipped with a green-yellow protective conductor, ensuring compliance with VDE standards for electrical installations. The designation NYY-J indicates a cable with PVC insulation and sheath, as well as an integrated protective conductor, while 3X6 RE describes the configuration with three conductors each of 6 mm² cross-section and round single-strand copper conductors.

Applications
This cable is suitable for use in underground installations, outdoor environments, and enclosed indoor spaces. It can be installed in cable ducts and is designed for permanent installations. Its use is recommended in areas requiring high mechanical and chemical resistance, as well as sufficient resistance to environmental influences. The cable's protection rating allows for installation underground and in damp environments, with the PVC insulation and outer sheath providing adequate insulation performance and mechanical strength.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, and is configured as RE (round single-strand). The conductors are insulated with PVC, with conductor identification according to VDE 0293-308. The designation J indicates that a green-yellow protective conductor is integrated, ensuring grounding and safety for the electrical installation. The filler layer ensures even distribution of the conductors within the cable cross-section and prevents conductor displacement during installation. The outer sheath is made of black PVC, resistant to mechanical stress, UV radiation, and moisture.

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 is used for quality testing and ensures the cable does not experience breakdowns even under increased voltage. The maximum operating temperature is +70 °C, with installation permitted at temperatures as low as -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-conductor cables and 12 times for multi-conductor cables, allowing for flexible installation. 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 executed according to current VDE standards. It can be combined with other cables from the NYY series, particularly in systems requiring grounding via an integrated protective conductor. Use in cable ducts or underground installation requires no additional protective measures, as the cable already provides the necessary mechanical and electrical safety. Connections are made using suitable cable lugs, cable glands, or other connection elements appropriate for the cable type and cross-section.

Installation and Mounting
Installation involves fixed laying, with required bending radii strictly observed to avoid mechanical damage. Outdoor or underground installation requires sufficient depth and protection against mechanical stress, especially when laid under roads or in areas with high load. Installation in cable ducts follows standard procedures, ensuring cables are not overloaded. Electrical connections are made using suitable connection elements designed for a cross-section of 6 mm².

Advantages in Operation
The cable offers high mechanical strength and resistance to environmental influences, enabling long service life and low maintenance frequency. The integrated grounding via the green-yellow protective conductor enhances installation safety. PVC insulation ensures reliable electrical insulation and protects against short circuits. Flame retardancy reduces the risk of fire spread in case of fire. Its suitability for various environments — from underground to indoor spaces — makes the cable a versatile solution for electrical installations.
