The cable of the brand VDE-Kabel, type NYY-O 1X120 RM, is a fixed-installed power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It is a copper earth cable with a cross-sectional area of 120 mm² per conductor, where the conductors are made as round multi-strand (RM). The designation O indicates that the cable is manufactured without a green-yellow protective conductor. The insulation of the conductors is made of PVC, and the outer sheath is also made of black PVC, ensuring high mechanical and chemical resistance. The cable construction includes a filler sheath that stabilizes the conductors and ensures an even shape of the cable.

Applications
This cable is suitable for use in various environments, including underground installation, outdoor applications, indoor spaces, and cable ducts. It is particularly suitable for applications requiring high mechanical load capacity and resistance to environmental influences. Outdoor use is possible due to the black-colored PVC sheathing and flame-retardant properties. The cable construction is designed for permanent, fixed installation, with bending strength ensured by the multi-strand design of the conductors.

Functions and Equipment in Detail
The conductors are marked according to VDE 0293-308, with marking applicable for 1 to 5 conductors. From 6 conductors onwards, marking is done in black with white digits. The conductors are made of bare copper, manufactured according to VDE 0295. The multi-strand design (RM) provides better bending strength and flexibility compared to single-strand conductors, which is advantageous during installation and for later movements within cable ducts. The filler sheath ensures even distribution of the conductors and prevents shifting within the cable.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for voltages up to 1 kV with a test voltage of 4 kV. The maximum operating temperature is +70 °C, with installation allowed at temperatures from -5 °C to +70 °C. After installation, the cable can be operated at temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-strand conductors and 12 times for multi-strand conductors, enabling flexible installation. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning the cable does not produce flames during a fire test and does not propagate flame beyond a certain area.

Compatibility and Accessories
The cable is designed for use in electrical installations requiring fixed installation. It is compatible with standard installation techniques for earth and indoor cables. The use of cable reels, typical for this product, enables efficient and damage-free installation. The cable construction does not require additional protective measures during installation, as the PVC insulation and outer sheath already provide the necessary mechanical and electrical protection.

Installation and Mounting
Installation is carried out by fixed laying in the ground, in cable ducts, or in indoor spaces. Installation should occur at temperatures between -5 °C and +70 °C to ensure optimal deformation and anchoring of the cable. Bending radii depend on the conductor construction: for multi-strand conductors, the bending radius is 12 times the cable diameter. Installation is typically done from reels, with length varying according to the delivery scope. Connection of the conductors is made using suitable cable lugs or cable glands designed for a cross-section of 120 mm².

Advantages in Operation
The cable offers high mechanical stability and resistance to environmental influences such as moisture, UV radiation, and chemical effects. The PVC insulation ensures reliable electrical insulation and prevents short circuits. The flame-retardant design increases safety in case of fire, as the flame is not propagated. The multi-strand conductor construction allows flexible installation and reduces the risk of breaks during bending.
