The cable of the brand VDE-Kabel, type NYY-O 1X150 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 150 mm² per conductor, where the conductors are manufactured as round multi-strand (RM). The designation O indicates that the cable is supplied 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.

Applications
This cable is suitable for installation in earth ducts, outdoor installations, indoor spaces, and cable ducts. It is particularly suitable for applications requiring high mechanical load capacity and resistance to environmental influences. Installation in the ground or outdoors is possible due to the robust PVC sheathing and fixed installation. The cable type is designed for supplying electrical installations, machines, and equipment in industrial and commercial environments.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, and is designed as round multi-strand (RM), offering better flexibility and bendability compared to single-strand conductors. The conductors are insulated with PVC, with marking according to VDE 0293-308. For a conductor cross-section of 150 mm², the marking is indicated by the type designation O (without green-yellow protective conductor). A filler layer ensures even distribution of the conductors within the cable cross-section and supports mechanical stability. The black-colored outer sheath made of PVC protects the cable against mechanical stress, moisture, and UV radiation.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for use in low-voltage networks up to 1 kV. The test voltage of 4 kV serves quality assurance and ensures the cable remains stable even under increased electrical load. The maximum operating temperature is +70 °C, with the cable tolerating temperatures from -5 °C to +70 °C during installation. After installation, it can be operated at temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-conductor cables and 12 times for multi-conductor cables, enabling installation in tight bends. The flame retardancy corresponds to VDE 0472 Part 804, test type B (equivalent to IEC 332-1), meaning the cable does not produce flames during a fire test and does not propagate flame beyond a defined area.

Compatibility and Accessories
The cable is suitable for use with standard cable lugs, cable glands, and other connection elements designed for PVC-insulated cables with a cross-section of 150 mm². It can be installed in combination with other cables of type NYY-O or similar earth cables in a cable duct or in the ground. The use of cable reels (e.g., 1000 m) is common to achieve longer installation lengths without additional connections.

Installation and Mounting
Installation is fixed, and the specified bending radii must be observed to ensure the mechanical integrity of the cable. Installation in the ground requires sufficient depth and protective measures against mechanical damage. Installation in indoor spaces or cable ducts must comply with electrical standards and respective installation regulations. Connection of the conductors is made using suitable cable lugs or other connection techniques designed for a cross-section of 150 mm².

Operational Advantages
The cable offers high mechanical stability, resistance to environmental influences, and a long service life. The PVC insulation and outer sheath ensure high insulation strength and protection against moisture. The flame-retardant design reduces fire risk during operation. The multi-strand design (RM) allows better flexibility during installation, especially in tight bends or multiple bends.
