VDE-Kabel 242573 NAYY-J 4x50 mm² SE Alu-earth cable drum Eca content_copy

The aluminium earth cable NAYY-J 4X 50 SE from VDE-Kabel is an energy and control cable designed for use in soil, outdoors, in industrial plants, power stations, switchgear, and local networks. It is also suitable for use in water, in dry and damp indoor environments, and in cable ducts, provided no mechanical damage is expected. The cable features a sector-shaped, single-wire aluminium conductor in accordance with VDE 0295 and is equipped with a PVC core insulation and outer sheath in black. The core identification follows VDE 0293-308, where the J in the type designation indicates the integrated protective earth conductor function. The filler sheath ensures even distribution of the cores within the cable cross-section.

Applications
This cable is suitable for a wide range of applications in the field of energy and control technology, particularly in industry, power stations, and local networks. It can be laid in soil, is suitable for use in water, and can also be used indoors regardless of humidity. Installation takes place in cable ducts or directly in soil, provided no mechanical loads occur. The operating conditions include both dry and damp environments, with a maximum operating temperature of +70 °C.

Functions and Equipment in Detail
The conductor is made of aluminium and is sector-shaped single-wire (SE), enabling optimal current conduction and efficient use of space within the cable cross-section. The PVC insulation of the cores ensures high electrical insulation and protection against external influences. The protective earth conductor function (J) is integrated, enhancing safety during operation. The filler sheath provides a stable cable structure and prevents core displacement. The black PVC outer sheath offers additional protection against mechanical stress and environmental influences.

Technology Explained Simply
The rated voltage is 0.6/1 kV, enabling use in low-voltage networks. The test voltage of 4 kV ensures the electrical strength of the cable. Temperature ranges are defined: during installation, between -5 °C and +50 °C; after installation, between -30 °C and +70 °C. The maximum operating temperature is +70 °C, describing the thermal load capacity of the cable under operating conditions. The bending radius is 12 times the cable diameter, which must be considered during installation to avoid damage. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), ensuring limited flame spread in case of fire.

Compatibility and Accessories
The cable is suitable for use in existing and new installations in the field of energy and control technology. It can be used in combination with suitable cable glands, cable lugs, and other connection elements, provided these are designed for the rated voltage and cross-section. Use in local networks, industrial plants, and power stations requires compliance with the respective standards and regulations.

Installation and Mounting
Installation must consider the specified temperature ranges and bending radius. The cable is suitable for use in soil and cable ducts. Outdoor or underwater installation requires careful planning to avoid mechanical damage. Core connections are made using suitable connection elements designed for a cross-section of 50 mm².

Advantages in Operation
The cable offers high electrical conductivity due to the aluminium conductor and a stable structure due to the filler sheath. The integrated protective earth conductor function enhances safety during operation. The PVC insulation and outer sheath provide high protection against environmental influences. Flame retardancy according to VDE 0472 Part 804, test method B, reduces fire risk. Use in various environments, from dry indoor spaces to water and soil, makes the cable a versatile solution for energy and control applications.
