The VDE-Kabel NAYY-J 4X185 SE is an aluminium earth cable designed for use as power and control cable in outdoor applications, in soil, in power plants, industrial and switchgear installations, in water, in dry and damp indoor areas, in cable ducts, and in local networks. Use is subject to the condition that no mechanical damage is expected. The cable features a sector-shaped, single-wire aluminium conductor in accordance with VDE 0295, ensuring high electrical conductivity and mechanical stability. The cores are insulated with PVC, with core identification according to VDE 0293-308. A filler layer ensures even distribution of the cores within the cable cross-section. Type J denotes the version with integrated protective conductor, which is required for safety in the event of a fault. The outer sheath is made of black PVC, resistant to environmental influences such as UV radiation and moisture.

Applications
This cable is designed for a wide range of applications in the field of power supply and control. It is particularly suitable for use in soil, in water, and in industrial environments where high mechanical and chemical resistance is required. Use in local networks and in cable ducts is also intended, provided no mechanical loads occur. The combination of aluminium conductor and PVC insulation makes it a cost-effective solution for medium-voltage applications.

Functions and Equipment in Detail
The sector-shaped aluminium conductor (SE) enables a compact cross-sectional shape, reducing space requirements in cable ducts or in soil. The PVC insulation provides sufficient electrical insulation and is resistant to moisture and minor mechanical loads. The integrated protective conductor (J) ensures electrical safety and meets the requirements for protective conductors in electrical installations. The filler layer ensures even distribution of the cores and prevents individual conductors from shifting within the cable interior.

Technology Explained Simply
The rated voltage of 0.6/1 kV makes the cable suitable for applications in low-voltage networks, as commonly used in industry, public areas, and residential zones. The test voltage of 4 kV serves quality control and ensures insulation strength. The operating temperature is a maximum of +70 °C, enabling safe use under normal ambient conditions. During installation, the temperature range is between -5 °C and +50 °C; after installation, it is between -30 °C and +70 °C. The bending radius is 12 times the cable diameter, allowing flexible installation without damaging the conductors. Flame retardancy in accordance with VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures that the cable does not act as a flame propagation source in case of fire and limits flame spread.

Compatibility and Accessories
The cable is suitable for use in existing and new installations in the field of power and control technology. It can be used in combination with appropriate cable glands, cable lugs, and other connection elements designed for aluminium conductors. The use of special tools for connecting aluminium conductors is recommended to ensure a reliable electrical connection.

Installation and Mounting
Installation is carried out by laying in soil, in cable ducts, or in water, while complying with the specified temperature and bending radius requirements. The cable is not intended for use in areas with high mechanical loads or strong chemical influences. Installation should be performed to avoid mechanical damage, particularly at bending points. Connections of the conductors are made using suitable connection elements designed for aluminium conductors.

Operational Advantages
The cable offers high electrical conductivity with low weight, facilitating installation and mounting. The PVC insulation and black-coloured outer sheath provide high resistance to environmental influences. The integrated flame retardancy increases operational safety. The use of aluminium as conductor material reduces material costs compared to copper, without impairing electrical properties within the intended application range.
