The cable of type designation NYCWY 4X16 RE/16 from VDE-Kabel is a fixed-installed power and control cable, primarily used in industrial and switchgear installations, power plants, and local networks. It is designed for safe power transmission and control in environments where enhanced electrical and mechanical protection against contact voltage is required. The cable is designed for installation outdoors, in the ground, indoors, and in cable ducts, making it suitable for a wide range of applications in industrial and public sectors.

Applications
This cable is designed for use in technically demanding environments, particularly in industrial electrical engineering, for supplying switchgear, and in power plants. It is also used in local networks where high mechanical and electrical robustness is required. Installation can take place in the ground as well as indoors, with outdoor installation and installation in cable ducts also being possible. The construction ensures safe and durable performance under these conditions.

Functions and Equipment in Detail
The cable consists of four individual conductors, each with a cross-section of 16 mm², executed as round single-strand (RE). The conductors are made of bare copper according to VDE 0295. Each conductor is insulated with PVC, with conductor identification according to VDE 0293-308. A filler layer ensures even distribution of the conductors within the cable cross-section. A concentric conductor, made of bare copper wires, is helically stranded around the common conductor sheath and equipped with a counter-winding made of copper tape. The inner layer consists of copper wires, while the outer layer is made of copper tape. This design ensures effective shielding and improved protection against contact voltage. The outer sheath is made of black PVC, providing high mechanical strength and weather resistance.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, meaning it is designed for operating voltages up to 1 kV. The test voltage of 4 kV serves quality control and ensures the cable remains stable even under increased voltage. 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 damaging the cable. Flame retardancy according to VDE 0472 T. 804, test method B (equivalent to IEC 332-1), ensures limited flame spread in case of fire, increasing operational safety.

Compatibility and Accessories
The cable is suitable for use in existing and new installations in industrial and public sectors. It can be connected using standard cable connectors, cable lugs, and other compatible connection elements designed for PVC-insulated cables with a cross-section of 16 mm². The use of cable protection conduits or cable ducts is possible, with the mechanical durability of the cable ensured by the black PVC outer sheath.

Installation and Mounting
Installation is done by fixed laying, ensuring the specified bending radii are observed to avoid damaging the cable. Underground installation requires sufficient depth and protective measures against mechanical damage, such as using protective conduits. Outdoor and indoor installation must comply with applicable regulations for electrical installations. The conductors are connected using appropriate cable lugs or connectors designed for a cross-section of 16 mm².

Operational Advantages
The cable offers high mechanical and electrical stability, enabling long service life and low maintenance frequency. The integrated shielding provided by the concentric conductor and copper tape ensures improved protection against contact voltage. Flame retardancy according to VDE 0472 T. 804, test method B, increases operational safety. The use of PVC as insulating and outer sheath material ensures high weather resistance and mechanical strength, making the cable particularly suitable for outdoor and industrial environments. The combination of copper conductors and PVC insulation ensures reliable and high-performance power transmission.
