The cable of type designation NYCWY 4X95 SM/50 from VDE-Kabel is a fixed installation 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 applications requiring enhanced electrical and mechanical protection against contact voltage. The cable is suitable for installation outdoors, in the ground, indoors, and in cable ducts, and features a concentric conductor providing additional protection against electrical fields.

Applications
This cable is designed for use in industrial installations, power supply networks, and power plants where high mechanical and electrical loads occur. It is particularly suitable for applications requiring safe and reliable power supply, such as in process automation, machine installations, or public power supply. Installation takes place in underground trenches, cable ducts, or outdoors, with the PVC insulation and black-colored outer sheath ensuring mechanical and chemical resistance.

Functions and Equipment in Detail
The conductor consists of bare copper in accordance with VDE 0295, with the execution sector-shaped stranded (SM) selected. This shape optimizes space requirements within the cable cross-section and improves current flow under high loads. The conductors are insulated with PVC and marked according to VDE 0293-308, enabling clear identification of individual conductors. A filler layer ensures even distribution of the conductors within the cable cross-section. The concentric conductor, made of bare copper wires, is helically stranded around the common conductor sheathing and equipped with a counter-twist made of copper tape, providing effective protection against electrical fields and improved grounding.

Technology Explained Simply
The rated voltage is 0.6/1 kV, indicating the maximum voltage at which the cable can be safely operated. The test voltage of 4 kV is used for quality assurance and ensures the cable shows no insulation faults even under increased voltage. The operating temperature is limited to a maximum of +70 °C, defining the thermal load capacity of the cable. During installation, the temperature must be between -5 °C and +50 °C; after installation, the permissible temperature range is -30 °C to +70 °C. The bending radius is 12 times the cable diameter to prevent damage to the conductor or insulation. The flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures that the cable does not propagate live flame when exposed to fire, which is important in enclosed spaces and cable ducts.

Compatibility and Accessories
For connecting and protecting the cable, suitable accessories can be used, such as the sleeve VHR954, specifically designed for compacted conductors with a cross-section of 95 mm² and galvanized E-Cu material. This sleeve enables a secure and durable connection, especially under high mechanical loads.

Installation and Mounting
Installation must comply with the specified temperature and bending radius requirements. The cable is suitable for installation in underground trenches, cable ducts, and indoor spaces. Outdoor installation requires sufficient mechanical protection, e.g., via protective conduits or concrete plates, to prevent damage from external influences. Connection of the conductors is made using appropriate cable lugs or connectors, with the use of suitable accessories such as the VHR954 sleeve recommended.

Advantages in Operation
The cable offers high mechanical and electrical stability, required for use in demanding environments such as industrial installations or power plants. The concentric conductor ensures improved grounding and protection, while the PVC insulation and black-colored outer sheath provide high resistance to environmental influences such as moisture, UV radiation, and mechanical stress. The flame-retardant design increases safety in enclosed spaces and cable ducts. The sector-shaped conductor design optimizes space requirements and improves current flow under high loads.
