The cable of the brand VDE-Kabel, type NYY-J 4X95 SM, is a fixed installation power and control cable designed for use outdoors, in the ground, indoors, and in cable ducts. It is particularly suitable for applications requiring high mechanical and chemical resistance as well as secure power transmission. The cable features a protective earth conductor (designation J), making it suitable for use in electrical installations in accordance with VDE regulations.

Applications
This cable is intended for installation in underground ducts, outdoors, and indoors. It can also be installed in cable ducts, ensuring mechanical load capacity and resistance to external influences such as moisture or mechanical stress. It is typically used in industrial, commercial, or municipal electrical installations where permanent and reliable power supply is required.

Functions and Features in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, and is produced in sector-shaped, multi-strand configuration (SM). This design ensures optimal current conduction and improved flexibility, especially for larger cross-sections. The cores are insulated with PVC, providing high electrical insulation and chemical resistance. Core identification follows VDE 0293-308, with color coding and digit marking enabling identification of individual cores. The protective earth conductor is marked green-yellow, ensuring compliance with safety standards.

Technical Explanation
The cable features a filler layer that holds the cores together and ensures even distribution of mechanical stress. The outer sheath is made of black PVC, which is dust- and waterproof, making it suitable for outdoor use. The rated voltage is 0.6/1 kV, sufficient for most industrial and commercial applications. The test voltage of 4 kV ensures the cable’s electrical strength. The maximum operating temperature is +70 °C, with installation possible at temperatures as low as -5 °C. After installation, the cable can be operated at temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core conductors, enabling flexible installation. Flame retardancy complies with VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), ensuring limited flame propagation.

Compatibility and Accessories
The cable is designed for use in electrical installations executed according to VDE standards. It can be combined with other cables of types NYY, NYKY, NYZG2Y, or NYYÖ, provided technical requirements such as voltage, cross-section, and protection type are matched. The use of suitable cable lugs, cable glands, or cable entry plates is recommended to ensure a secure and durable connection.

Installation and Mounting
Installation is carried out by laying in the ground, in cable ducts, or outdoors. Laying should respect the specified bending radii to avoid damage. Temperature conditions during installation (minimum -5 °C) and during operation (up to +70 °C) must be observed. Underground laying typically requires sufficient depth and protective measures against mechanical damage, such as cable protection conduits.

Operational Advantages
The cable offers high mechanical strength, chemical resistance, and electrical reliability. The PVC insulation and outer sheath ensure long service life and resistance to external influences. The sector-shaped, multi-strand configuration (SM) provides better flexibility and even current distribution. Flame retardancy according to VDE 0472 Part 804, Test Method B, increases operational safety, especially in enclosed spaces or areas with increased fire risk.
