The NYCWY 3X70 SM/35 cable from Faber Kabel is a fixed installation power and control cable primarily used in industrial and switchgear installations, power plants, and local networks. It ensures safe power transmission and control in environments requiring enhanced electrical and mechanical protection against contact voltage. The cable is suitable for outdoor installation, underground, indoors, and in cable ducts, and features a concentric conductor providing additional protection. The construction is based on PVC insulation material and a black PVC outer sheath, offering protection against external influences such as moisture and mechanical stress.

Applications
This cable is designed for use in industrial plants, power supply networks, and power stations where high electrical safety and mechanical robustness are required. It is particularly suitable for underground installation, in cable ducts, or indoors, where it is subject to long-term load. Outdoor use is possible due to the PVC insulation and weather-resistant outer sheath, with temperature limits ranging from -30 °C to +70 °C. The maximum operating temperature is +70 °C, ensuring suitability for use in warm environments.

Functions and Equipment in Detail
The conductor is made of bare copper in accordance with VDE 0295, with the SM (sector-shaped multi-strand) configuration chosen to ensure optimal current conduction and mechanical stability. The cores are insulated with PVC and marked according to VDE 0293-308, enabling clear identification. A filler layer ensures even distribution of the cores and prevents displacement. The concentric conductor, consisting of bare copper wires helically stranded around the common core sheathing, is supplemented by a counter-wind of copper tape. This design provides effective protection against electrical interference and contact voltage.

Technology Explained Simply
The rated voltage is 0.6/1 kV, enabling use in medium-voltage installations. The test voltage of 4 kV ensures the electrical strength of the cable. Flame retardancy in accordance with VDE 0472 T. 804, test method B (equivalent to IEC 332-1), ensures that the cable is only limitedly flammable and does not propagate flames when exposed to fire. The bending radius is 12 times the cable diameter, allowing flexible installation without damage. Temperature ranges are clearly defined: during installation, the range is -5 °C to +50 °C; after installation, it is -30 °C to +70 °C. The maximum operating temperature of +70 °C ensures the cable remains stable even under load.

Compatibility and Accessories
The cable is designed for use with standard cable connectors, connection boxes, and switchgear rated for voltages up to 1 kV. It is equipped with concentric conductors providing effective grounding and protective functions. Installation is carried out in cable ducts, underground, or indoors, with the PVC insulation and outer sheath providing the necessary resistance to environmental influences.

Installation and Mounting
Installation requires adherence to the specified bending radius of 12 times the cable diameter to avoid material fractures or insulation defects. Installation is typically performed using cable reels, and cable ends should be carefully inspected for damage before installation. Connections to other cables or devices are made using appropriate cable lugs or connection boxes rated for the nominal voltage and cross-section. Temperature conditions during installation (–5 °C to +50 °C) must be observed to ensure correct installation.

Operational Advantages
The cable offers high electrical and mechanical stability, increasing reliability in critical installations. The PVC insulation and concentric conductor provide effective protection against contact voltage and interference. Flame retardancy in accordance with VDE 0472 T. 804, test method B, reduces fire risk and improves operational safety. The maximum operating temperature of +70 °C allows use in warm environments without impairing performance. Installation in various environments — underground, in cable ducts, or indoors — makes the cable versatile in application.
