Faber Kabel 901930400000 NAYY-J 4x25 mm² RE Alu-earth cable drum content_copy

The product is an aluminium earth cable of type designation NAYY-J 4X25 RE, manufactured by Faber Kabel. It is an energy and control cable intended 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 is equipped with a protective conductor, indicated by the designation „J“ in the type identifier. The designation „RE“ stands for a round, single-strand aluminium conductor, manufactured according to VDE 0295.

Applications
This cable is suitable for a wide range of applications in the field of energy and control technology. It can be installed in the ground, for example in local networks or for supplying industrial facilities. Due to its construction with PVC insulation and outer sheath, it is also suitable for use in water, provided no mechanical loads occur. Use in indoor areas, particularly in cable ducts, is also intended, with environmental conditions being either dry or damp.

Functions and Equipment in Detail
The conductor is made of aluminium and manufactured according to VDE 0295. The conductor shape is round and single-strand (RE), ensuring a stable and shape-retaining structure. Each core is insulated with PVC, with core identification according to VDE 0293-308. A filler layer ensures even distribution of the cores in the cable cross-section. The outer sheath is made of black PVC, providing high mechanical strength and weather resistance. The designation „J“ indicates that the cable includes a protective conductor, which is required for electrical safety during operation.

Technology Explained Simply
The rated voltage is 0.6/1 kV, indicating the maximum voltage at which the cable can be safely operated. The test voltage of 4 kV serves quality control and ensures the cable has the required insulation strength. The operating temperature is limited to a maximum of +70 °C, with cable installation recommended at temperatures between -5 °C and +50 °C. After installation, the cable can withstand temperatures from -30 °C to +70 °C. 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), meaning the cable does not produce a flammable flame during a flame test and thus exhibits limited flame spread.

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 other cables of type NAYY-J, particularly in various cross-sections, to ensure consistent installation. Use in local networks and for supplying industrial facilities is standard.

Installation and Mounting
During cable installation, the specified temperatures and bending radius of 12 times the cable diameter must be observed. Installation takes place in the ground, in cable ducts, or indoors, with environmental conditions being either dry or damp. Installation in water is also possible, provided no mechanical loads occur.

Operational Advantages
The cable offers high mechanical strength and weather resistance due to the black-coloured PVC outer sheath. Flame retardancy according to VDE 0472 Part 804, test method B, ensures increased safety during operation. The use of aluminium as conductor material enables a cost-effective and conductive solution. The maximum operating temperature of +70 °C ensures reliable performance even at higher ambient temperatures. The ability to be used in various environments, from ground to indoor areas, makes the cable a versatile solution for energy and control applications.
