The cable of the brand VDE-Kabel, type NYCY 5 X 2,5 RE/2,5, is a fixed installation power and control cable, primarily used in industrial and switchgear applications as well as in power plants. It is particularly suitable for environments where enhanced mechanical protection against touch voltage is required. The cable features a concentric conductor, providing additional protection and improved earthing, making it suitable for demanding industrial applications. The construction ensures high mechanical stability and electrical reliability under load.

Applications
This cable is designed for use in industrial environments, such as production facilities, switchgear installations, and power plants. It is especially suitable for systems requiring secure earthing and high protection against touch voltage. Installation is carried out in the ground or other fixed installations, where mechanical strength and resistance to external influences play a central role. Its use in power plants highlights the cable’s reliability under critical operating conditions.

Functions and Equipment in Detail
The cable consists of five bare copper conductors, manufactured as round single-strand (RE) according to VDE 0295. Each conductor is insulated with PVC, ensuring good electrical insulation and chemical resistance. Conductor identification follows VDE 0293-308, with conductors numbered from 1 to 5. A filler layer ensures even distribution of the conductors within the cable cross-section. The concentric conductor, made of bare copper wires stranded around the common core sheathing, is supplemented by a counter-twist made of copper tape. This construction ensures effective earthing and high protection against touch voltage. The outer sheath is made of black PVC, providing high mechanical strength and resistance to environmental influences.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, making it suitable for use in medium-voltage installations. The test voltage of 4 kV ensures electrical strength under high voltage conditions. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +50 °C during installation. After installation, it can withstand temperatures from -30 °C to +70 °C. The bending radius is 12 times the cable diameter, allowing flexible installation without compromising mechanical integrity. Flame retardancy according to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), limits flame spread in case of fire, enhancing safety in enclosed spaces.

Compatibility and Accessories
The cable is designed for use in industrial electrical installations and can be connected with standard connectors, cable lugs, and other electrical components designed for PVC-insulated cables. The use of concentric conductors requires special earthing connections to ensure proper earthing functionality. It is compatible with other cables in the NYCY series and can be integrated into existing installations, provided electrical and mechanical requirements are matched.

Installation and Mounting
Installation is carried out in the ground or other fixed installations. The installation temperature must be between -5 °C and +50 °C to ensure correct installation without damaging the cable. The bending radius of 12 times the diameter must be observed to avoid cracks or breaks in the insulation material. After installation, the cable must be properly connected and earthed, with the concentric conductor structure enabling a secure earthing connection. Installation requires professional expertise in electrical work, particularly when connecting the concentric conductor.

Operational Advantages
The cable provides high mechanical protection and reliable earthing, increasing safety in industrial facilities. The PVC insulation and black outer sheath ensure high resistance to environmental influences such as moisture, UV radiation, and mechanical stress. Flame retardancy according to VDE 0472 Part 804, Test Method B, reduces the risk of flame spread. The maximum operating temperature of +70 °C enables stable performance under normal operating conditions. Its use in power plants and switchgear installations underscores the product’s reliability and durability.
