VDE-Kabel 248117 NYCWY 4x25 mm² RM/16 mm² drum Eca PVC-insulated earth cable, concentric conductor content_copy

The cable of type designation NYCWY 4X25 RM/16 from VDE-Kabel is a fixed installation power and control cable, primarily used in industrial and switchgear applications, power plants, and local networks. It is designed for safe power transmission and control in installations where enhanced electrical and mechanical protection against contact voltage is required. The cable is suitable for installation outdoors, in the ground, indoors, and in cable ducts. It features a concentric conductor, providing additional protection against electrical fields and contact voltage.

Applications
This cable is designed for use in industrial environments, for power supply to machines and systems, and for power distribution in power plants and local networks. It is particularly suitable for applications requiring high mechanical and electrical safety. Installation takes place in underground trenches, outdoors, or in enclosed cable ducts, with environmental conditions such as temperature and humidity being taken into account.

Functions and Equipment in Detail
The conductor is made of bare copper according to VDE 0295, where RM stands for round multi-strand. The cores are insulated with PVC and marked according to VDE 0293-308, enabling clear identification of individual cores. A filler layer ensures even distribution of the cores within the cable cross-section. The concentric conductor is constructed from bare copper wires, helically stranded around the common core sheathing, supplemented by a counter-helix made of copper tape. This construction ensures effective protection against electrical fields and contact voltage. The outer sheath is made of black PVC, which resists mechanical stress and environmental influences.

Technology Explained Simply
The rated voltage is 0.6/1 kV, indicating the maximum voltage for which the cable is designed. The test voltage of 4 kV serves quality assurance and ensures the cable remains stable even under increased voltage. The operating temperature is limited to a maximum of +70 °C, while the cable can be installed at temperatures ranging from -5 °C to +50 °C. After installation, it can be exposed to temperatures from -30 °C to +70 °C. The bending radius is 12 times the cable diameter, which must be considered during installation to avoid damage. Flame retardancy according to VDE 0472 T. 804, test method B (equivalent to IEC 332-1), ensures fire behavior characteristics and prevents flame propagation along the cable.

Compatibility and Accessories
The cable is designed for use in existing and new installations in industrial and power supply applications. It can be connected to standard cable connectors, switchgear, and distributors designed for a rated voltage of 0.6/1 kV.

Installation and Mounting
Installation must consider the specified bending radii and temperature limits. The cable is suitable for installation in underground trenches, outdoors, or in cable ducts. Outdoor installation requires special care regarding fixation and protective measures against mechanical damage. Indoor installation is carried out in cable ducts or open routing, where flame retardancy plays an important role.

Operational Advantages
The cable provides high protection against contact voltage due to the concentric conductor, increasing operational safety. The PVC insulation and black-colored outer sheath ensure high mechanical and chemical resistance. Flame retardancy according to VDE 0472 T. 804, test method B, reduces fire risk and prevents flame propagation. The use of bare copper as conductor material ensures high electrical conductivity and reliability throughout the cable’s service life.

Core Functions
The cable is designed as a fixed installation power and control cable for use in industrial and power engineering applications. The use of PVC as insulating and protective sheath material, along with the concentric conductor made of copper wires and tape, ensures high safety and reliability. The rated voltage of 0.6/1 kV and test voltage of 4 kV define the electrical limits of the cable. Temperature ranges and bending radius are critical for correct installation and safe operation. Flame retardancy according to VDE 0472 T. 804, test method B, is an important safety feature, especially in enclosed spaces and when installed in cable ducts.
