VDE-Kabel 257768 NAYY-J 4x240 mm² SE Alu-Earth cable Eca content_copy

The VDE-Kabel NAYY-J 4X240 SE is an aluminium earth cable used as power and control cable in various industrial and infrastructural applications. It is designed for use outdoors, in the ground, in power plants, industrial and switchgear installations, in water, in dry and damp indoor areas, in cable ducts, and in local networks, provided no mechanical damage is expected. The cable features a sector-shaped, single-wire aluminium conductor according to VDE 0295, ensuring high electrical conductivity and mechanical stability. The cores are insulated with PVC, with core identification according to VDE 0293-308. The filler layer ensures even distribution of the cores within the cable cross-section, and the outer sheath is made of black PVC, enhancing mechanical and chemical resistance. The cable includes a protective earth conductor, indicated by the designation “J”.

Applications
This cable is designed for use in electrical installations and distribution networks, particularly in areas where installation in the ground or in cable ducts is required. It is suitable for power plants, industrial facilities, switchgear installations, and local networks where high electrical power must be transmitted. Use in water is also possible, provided environmental conditions meet technical specifications. Indoor use is permitted, provided no mechanical loads occur.

Functions and Equipment in Detail
The aluminium conductor in type SE (sector-shaped, single-wire) enables a compact cross-section form, ensuring efficient heat dissipation and reduced bending sensitivity at high current loads. The PVC insulation of the cores provides high electrical insulation performance and is resistant to moisture and minor mechanical stress. Core identification according to VDE 0293-308 ensures unambiguous identification of individual cores, which is beneficial during installation and maintenance. The filler layer ensures even core distribution and prevents uneven stress on the outer sheath. The black-coloured PVC outer sheath provides protection against UV radiation, moisture, and minor mechanical impacts.

Technology Explained Simply
The rated voltage of 0.6/1 kV defines the maximum voltage the cable can safely transmit during operation. The test voltage of 4 kV serves as a safety margin and is used during manufacturing for quality testing. The operating temperature is up to +70 °C, meaning the cable remains stable under these conditions without risk of insulation ageing. During installation, the permissible 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, which must be considered during installation to avoid damage. Flame retardancy according to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), means the cable does not propagate flames during a fire test, thus presenting a low fire hazard.

Compatibility and Accessories
The cable is designed for use in existing and new distribution networks, particularly in combination with other earth cables and distribution components. It is compatible with standard connectors and terminal boxes designed for aluminium conductors. The use of special aluminium connectors is recommended to ensure a secure and durable electrical connection. Combination with other cable types is possible, provided electrical and mechanical requirements are compatible.

Installation and Mounting
Installation is carried out by laying in the ground, in cable ducts, or indoors. Laying in the ground requires sufficient depth and protection against mechanical loads. When laying outdoors, the UV resistance of the outer sheath must be considered. Bending sensitivity must be taken into account with a bending radius of 12 times the cable diameter. Core connections are made using suitable aluminium connectors, with core identification according to VDE 0293-308 enabling correct assignment. Installation must comply with applicable regulations and standards.

Operational Advantages
The cable offers high electrical conductivity due to the aluminium conductor, minimizing losses. The PVC insulation and outer sheath provide high resistance to moisture, UV radiation, and minor mechanical stress. Flame retardancy according to VDE 0472 Part 804, Test Method B, increases operational safety. Use in various environments, including water, expands application possibilities. The sector-shaped conductor form enables compact installation and efficient heat dissipation.

Protection Class
The cable is designed for outdoor and underground use, with the PVC outer sheath providing sufficient protection against moisture and minor mechanical stress. Flame retardancy according to VDE 0472 Part 804, Test Method B (IEC 332-1), ensures low fire hazard. The operating temperature of +70 °C and the temperature range during installation (-5 °C to +50 °C) and after installation (-30 °C to +70 °C) allow flexible use in various climatic conditions.

Aluminium Conductor
The aluminium conductor in type SE (sector-shaped, single-wire) offers high electrical conductivity and mechanical stability. The sector-shaped form reduces the bending radius and enables compact installation. The use of aluminium reduces cable weight compared to copper conductors, facilitating installation.

Rated Voltage
The rated voltage of 0.6/1 kV defines the maximum voltage the cable can safely transmit during operation. This is crucial for selecting the cable based on the electrical system.

Flame Retardancy
Flame retardancy according to VDE 0472 Part 804, Test Method B (IEC 332-1), means the cable does not propagate flames during a fire test, increasing operational safety.

Core Identification
Core identification according to VDE 0293-308 enables unambiguous identification of cores, which is beneficial during installation and maintenance.

PVC Insulation
The PVC insulation of the cores provides high electrical insulation performance and is resistant to moisture and minor mechanical stress.
