The VDE-Kabel NYY-O 1X240 RM 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 power and control signals in industrial, commercial, and municipal installations. The cable is configured as a single-core model, with the conductor made of bare copper and manufactured as round multi-strand (RM) in accordance with VDE 0295.

Applications
This cable is suitable for use in underground installations, outdoor environments, and indoor spaces. It can be installed in cable ducts and is appropriate for applications in power supply, building automation, industrial control technology, and public infrastructure. Outdoor use requires high mechanical and chemical resistance, which is ensured by the PVC outer sheath and robust construction.

Functions and Features in Detail
The conductor is made of bare copper, manufactured as round multi-strand (RM) in accordance with VDE 0295. This ensures high flexibility and mechanical strength, particularly under frequent bending stress. The core insulation is made of PVC, providing good electrical insulation and chemical resistance. Core identification follows VDE 0293-308; for single-core cables, no specific identification is required. The filler layer ensures even distribution of cores and protects against mechanical damage. 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 is used for safety testing and ensures insulation strength. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +70 °C during installation and from -30 °C to +70 °C after installation. The bending radius is 15 times the cable diameter for single-core cables and 12 times for multi-core cables, enabling safe installation without mechanical damage. Flame retardancy complies with VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), meaning the cable does not propagate flame during a fire test and thus presents limited fire hazard.

Compatibility and Accessories
The cable is compatible with standard installation techniques for underground and indoor installations. It can be combined with appropriate cable protection conduits, cable glands, and connection components suitable for PVC insulation. Tools for cable processing, such as cutting tools or cable cutters, are required to process the cable cleanly.

Installation and Mounting
Installation involves laying the cable in the ground, in cable ducts, or indoors. The laying must ensure the specified bending radius is maintained to avoid mechanical damage. Outdoor installation requires sufficient depth and protection against mechanical impacts. Cable connections are made using suitable cable lugs or cable glands designed for a cross-section of 240 mm². Electrical connections must be carried out in accordance with applicable regulations and standards.

Operational Advantages
The cable offers high mechanical strength, chemical resistance, and electrical insulation. The use of PVC as insulation and outer sheath material ensures long service life and resistance to environmental influences. The flame-retardant design reduces fire hazard and increases operational safety. The single-core construction with RM structure allows flexible and robust installation, particularly in systems with high mechanical loads.

Protection rating, operating voltage, copper conductor, PVC insulation, flame retardancy, and underground installation are the key technical features characterizing the cable. The combination of these properties makes it a reliable product for power and control technology in various applications.
