The cable of the brand Faber Kabel, type NYY-J 3X185/95 SM, is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, as well as in cable ducts. It is used for the transmission of electrical energy and control signals in industrial, commercial, and municipal installations. The designation NYY-J indicates a cable with PVC insulation of the conductors and a PVC outer sheath, where the addition J stands for the integrated green-yellow protective earth conductor. The configuration 3X185/95 SM describes three main conductors each with a cross-section of 185 mm² and one protective earth conductor with 95 mm², where the designation SM stands for sector-shaped multi-strand, enabling optimized space utilization and mechanical stability within the cable.

Applications
This cable is suitable for use in underground installations, outdoor environments, and indoor spaces where high mechanical and chemical resistance is required. It is commonly used in building electrical engineering, industrial plant cabling, and for supplying machines and installations. Installation is carried out either directly in the ground or in cable ducts, where the PVC insulation and outer sheath provide sufficient protection against moisture, mechanical stress, and environmental influences.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, and is constructed in a sector-shaped, multi-strand configuration (SM). This design ensures even current distribution and reduces inductance in the cable. The conductors are insulated with PVC, with conductor identification according to VDE 0293-308. The green-yellow protective earth conductor (J) is clearly identifiable and complies with regulations for protective earth conductors in electrical installations. A filler layer ensures a stable cable structure and prevents displacement of the conductors relative to each other.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for operating voltages up to 1 kV, with a test voltage of 4 kV to ensure insulation strength. The maximum operating temperature is +70 °C, with installation possible at temperatures from -5 °C. After installation, the cable can be operated at temperatures from -30 °C to +70 °C, enabling broad application in various climate zones. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core cables, allowing flexible installation even in tight radii. Flame retardancy corresponds to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), meaning the cable does not propagate flame during a flame test and thus presents limited fire hazard.

Compatibility and Accessories
The cable is designed for use in electrical installations executed according to applicable standards for low-voltage systems. It is compatible with standard cable lugs, cable glands, and other connection elements designed for PVC insulation and copper conductors. Use in cable ducts or direct burial in the ground requires no additional protective measures, as the cable is already equipped with a protective PVC outer sheath.

Installation and Mounting
Installation is carried out by direct burial in the ground or in cable ducts. Installation should be performed while observing the specified bending radius to avoid mechanical damage. Connections of the conductors are made using suitable cable lugs or other connection elements designed for a cross-section of 185 mm². The green-yellow protective earth conductor must be connected to the protective earth terminal according to VDE regulations.

Operational Advantages
The cable offers high mechanical strength, good heat resistance, and sufficient insulation strength. The PVC insulation and outer sheath provide high resistance against moisture, UV radiation, and chemical influences. The sector-shaped conductor design reduces inductance and improves current distribution. The integrated protective earth conductor (J) meets the requirements for electrical safety in installations.
