VDE-Kabel NAYY-J 4X 35 RE is an aluminium earth cable designed for use as power and control cable in outdoor applications, underground installations, power plants, industrial and switchgear installations, as well as in local networks. It is also suitable for use in water, in dry and damp indoor environments, in cable ducts, and in other areas where no mechanical damage is expected. The cable features an aluminium conductor in accordance with VDE 0295, manufactured in a round single-wire configuration (RE), and is equipped with PVC insulation for the conductors and an outer sheath. The outer sheath is black and provides protection against external influences. Conductor identification follows VDE 0293-308, and the cable includes a protective earth conductor, indicated by the designation “J”.

Applications
This cable is designed for use in various industrial and power engineering applications. It is laid underground, for example in local networks or for supplying industrial facilities, and is also suitable for use in water. Use in indoor environments, particularly in dry and damp conditions, as well as in cable ducts, is also intended. The application is subject to the condition that no mechanical damage is expected from external influences such as pressure, tension, or abrasion.

Functions and Equipment in Detail
The conductor is made of aluminium and manufactured in accordance with VDE 0295, ensuring standardised quality and electrical conductivity. The round single-wire configuration (RE) provides a stable structure and even current distribution. Conductor insulation is made of PVC, offering good electrical insulation and mechanical strength. The filler layer ensures even distribution of the conductors within the cable cross-section and prevents displacement. The protective earth conductor, indicated by the designation “J”, enables safe earthing and protection against electrical hazards. The black PVC outer sheath protects the cable against external influences such as moisture, UV radiation, and mechanical stress.

Technology Explained Simply
The cable is rated for a nominal voltage of 0.6 / 1 kV, making it suitable for use in low-voltage networks. The test voltage is 4 kV, confirming the electrical strength of the insulating material under test conditions. The maximum operating temperature is +70 °C, and after installation, the cable can be operated in the temperature range of -30 °C to +70 °C. During installation, the temperature must be between -5 °C and +50 °C. The bending radius is 12 times the cable diameter, allowing safe bending without damaging the conductor. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning the cable does not propagate flame during a flame test, thus preventing limited flame spread.

Compatibility and Accessories
The cable is suitable for use in existing and new installations in power supply and industrial applications. It can be laid in cable ducts, underground, or in water, provided environmental conditions meet the specified requirements. Use in local networks and for supplying industrial facilities is standard. It is compatible with other cables of the same nominal voltage and similar construction, especially in systems requiring earthing via a protective earth conductor.

Installation and Mounting
Installation must comply with specified temperature conditions: during laying, the temperature must be between -5 °C and +50 °C. After installation, the cable can be operated in the temperature range of -30 °C to +70 °C. The bending radius is 12 times the cable diameter, which must be considered during bending to avoid cable damage. Laying occurs underground, in cable ducts, or in water, while avoiding mechanical damage. Electrical connections are made using suitable cable lugs or other connection techniques suitable for aluminium conductors.

Operational Advantages
The cable offers high electrical conductivity due to the aluminium conductor and stable insulation due to PVC. Flame retardancy according to VDE 0472 Part 804, test method B, enhances operational safety. Use in various environments, including water and underground, expands application possibilities. Integrated earthing via the protective earth conductor improves safety and meets requirements for protection against electrical hazards. The robust construction with filler layer and black PVC outer sheath ensures long service life and reliability under various operating conditions.

Protection Rating
The cable is designed for outdoor and underground use, where PVC insulation and the outer sheath provide sufficient protection against moisture, UV radiation, and mechanical stress. The specified temperature ranges and bending radius ensure safe installation and operational reliability. Flame retardancy according to VDE 0472 Part 804, test method B (IEC 332-1), prevents limited flame spread in case of fire.

Operating Voltage
The nominal voltage of 0.6 / 1 kV makes the cable suitable for use in low-voltage networks, particularly in power supply and industrial installations. The test voltage of 4 kV confirms the electrical strength of the insulating material under test conditions.
