The copper earth cable NYY-J 5 X 6 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 green-yellow protective conductor (designation J), making it suitable for use in electrical installations in accordance with VDE regulations. The designation RE indicates a round single-strand copper conductor manufactured in accordance with VDE 0295.

Applications
This cable is intended for use in underground installations, outdoor environments, and enclosed spaces. It is suitable for supplying machines, systems, lighting systems, and other electrical devices requiring fixed installation. Use in cable ducts enables structured and secure cable routing in buildings and production facilities. The PVC insulation and black outer sheath ensure high mechanical and chemical resistance.

Functions and Equipment in Detail
The conductor is made of bare copper manufactured in accordance with VDE 0295. The cores are insulated with PVC and marked in accordance with VDE 0293-308. For up to five cores, colour coding is used, with the green-yellow core serving as the protective conductor. From six cores onwards, black-white marking with numbers is used. A filler layer ensures uniform shape and mechanical stability of the cable. The black PVC outer sheath protects the cable against external influences such as moisture, mechanical stress, and UV radiation.

Technology Explained Simply
The cable is rated for a nominal voltage of 0.6/1 kV, making it suitable for most industrial and commercial applications. The test voltage is 4 kV, highlighting the electrical strength of the insulating material. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +70 °C during installation. After installation, it can be exposed to temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core conductors, enabling flexible installation. Flame retardancy corresponds to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), meaning the cable does not propagate flame during a flame test and thus presents limited fire hazard.

Compatibility and Accessories
The cable is designed for use in electrical installations requiring fixed installation. It is compatible with standard cable connectors, sockets, switches, and other electrical components rated for a nominal voltage of 0.6/1 kV. Use in underground installations may require additional protective measures such as cable protection conduits or ducts, if environmental conditions involve increased mechanical stress or moisture. Connections to other cables or devices are made using appropriate connection means complying with relevant standards.

Installation and Mounting
Installation is carried out by fixed laying in the ground, in cable ducts, or indoors. Laying must ensure the specified bending radius is maintained to avoid mechanical damage. Cable installation should consider environmental conditions such as temperature and humidity. Connections to electrical devices or outlets are made using suitable connection means complying with VDE regulations. Proper installation ensures functionality and safety of the cable throughout its entire service life.

Advantages in Operation
The cable offers high mechanical strength and resistance to external influences such as moisture, UV radiation, and chemical substances. The PVC insulation ensures reliable electrical insulation, while the green-yellow protective conductor enhances electrical safety. The flame-retardant design reduces fire risk in the event of a short circuit. Use in underground installations and cable ducts enables structured and secure cable routing, facilitating maintenance and inspection. The high operating temperature of +70 °C allows use in warm environments, such as those found in production facilities or industrial rooms.
