The cable of the brand VDE-Kabel, type NYY-J 4X1.5 RE TR, is a fixed-installed power and control cable designed for use outdoors, underground, indoors, and in cable ducts. It is a copper earth cable with PVC insulation and a black-colored outer sheath, suitable for versatile applications in electrical installation engineering due to its construction and materials. The designation NYY-J indicates a cable with a green-yellow protective conductor, which is necessary for the safe earthing of electrical devices and systems. The type RE describes a round single-strand copper conductor, ensuring stable and durable conductivity.

Applications
This cable is designed for use in various environments, including outdoors, underground, indoors, and in cable ducts. It is particularly suitable for supplying electrical devices, machines, and systems requiring fixed installation. Use in soil requires high mechanical stability and resistance to environmental influences, which is ensured by the PVC insulation and robust outer sheath. Indoor application is also possible, as the cable meets the required safety standards.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295. The designation RE means it is a round single-strand conductor, providing high mechanical strength and uniform current conduction. The cores are insulated with PVC, with core identification according to VDE 0293-308. For up to five cores, identification is done by color, with the designation J indicating the inclusion of a green-yellow protective conductor. The filler sheath ensures even distribution of the cores in the cable cross-section and prevents individual conductors from shifting. The outer sheath is made of black PVC, which can withstand mechanical stress and environmental influences such as moisture and UV radiation.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for electrical systems with an operating voltage up to 1 kV. The test voltage of 4 kV is used to check insulation strength and ensures the cable does not experience breakdowns even under increased voltage. The operating temperature is a maximum of +70 °C, with the cable tolerating temperatures from -5 °C to +70 °C during installation and from -30 °C to +70 °C after installation. This makes it suitable for use in various climate zones. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core, enabling safe and damage-free installation. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures the cable does not easily ignite and does not propagate flame, increasing safety in electrical systems.

Compatibility and Accessories
The cable is designed for use in electrical systems requiring fixed installation. It is compatible with standard installation techniques and materials, such as cable ducts, underground conduits, and electrical distributors. Use with other cable types is possible, provided the electrical and mechanical requirements of the respective system are met.

Installation and Mounting
Installation is carried out by fixed laying in soil, cable ducts, or indoors. Laying requires adherence to the specified bending radii to avoid damaging the conductors or insulation. Underground laying requires sufficient depth and protective measures against mechanical stress, such as laying in protective conduits. Connection of the cable to electrical devices or distributors is done using appropriate cable lugs or plug connectors designed for the respective cross-section size.

Advantages in Operation
The cable offers high mechanical stability, resistance to environmental influences, and secure power supply. The PVC insulation and black-colored outer sheath ensure long service life and low maintenance requirements. Flame retardancy increases safety in electrical systems, especially in enclosed spaces. The use of a green-yellow protective conductor ensures safe earthing and protects people from electrical hazards. The high operating temperature of +70 °C allows use in systems with high thermal loads.
