The cable of the brand Faber Kabel, type NYCY 10 X 2,5 RE/4,0, is a fixed installation earth cable from the category copper earth cable NYCY / NYCWY, specifically designed for use in industrial and switchgear installations as well as in power plants. It serves as an energy and control cable and offers enhanced mechanical protection against contact voltage, making it particularly suitable for applications with high safety requirements. The cable features a concentric conductor, providing additional protection and improved electrical conductivity.

Applications
This cable is designed for use in industrial environments where high mechanical load capacity and electrical safety are required. It is primarily used in switchgear installations, power plants, and other facilities with fixed wiring, where the risk of contact voltage due to mechanical impact must be minimized. The cable is used in underground installations, with its structure designed to withstand loads encountered in the ground.

Functions and Equipment in Detail
The conductor is made of bare copper according to VDE 0295, manufactured as round single-strand (RE). The cores are insulated with PVC, ensuring high electrical insulation and chemical resistance. Core identification follows VDE 0293-308: for 1 to 5 cores, identification is done according to the standard; from 7 cores onwards, cores are marked black with white digits. A filler layer ensures even distribution of cores within the cable cross-section. The concentric conductor consists of bare copper wires stranded around the common core sheathing, supplemented by a counter-twist made of copper tape, with copper wires arranged in the inner layer and copper tape in the outer layer. This construction improves electrical conductivity and provides additional protection.

Technology Explained Simply
The cable is rated for a nominal voltage of 0.6 / 1 kV, making it suitable for most industrial applications. The test voltage is 4 kV, highlighting the cable’s electrical strength. The maximum operating temperature is +70 °C, while the cable can be installed at temperatures between -5 °C and +50 °C and withstands temperatures from -30 °C to +70 °C after installation. The bending radius is 12 times the cable diameter, allowing flexible installation without compromising mechanical integrity. Flame retardancy complies with VDE 0472 Part 804, test type B, equivalent to IEC 332-1 — meaning the cable does not produce a flammable flame during a fire test, thus presenting a low fire hazard.

Compatibility and Accessories
The cable is designed for use in existing and new installations requiring high mechanical stability and electrical safety. It is compatible with other cables in the NYCY series, particularly in systems requiring a concentric conductor. Use in underground installations requires no additional protective measures, as the cable is already designed for this application. It can be combined with appropriate connection components, such as cable lugs or switchgear boxes, suitable for the nominal voltage and cross-section.

Installation and Mounting
Installation is carried out by underground laying, with ambient temperature during installation ranging from -5 °C to +50 °C. The cable must not be bent beyond the specified bending radius of 12 times the diameter to avoid mechanical damage. Installation takes place in a suitable trench, with environmental conditions matching the specified temperature range. After installation, the cable must be properly connected and earthed, complying with relevant electrical standards and regulations.

Advantages in Operation
The cable offers high mechanical strength and electrical safety, enhancing operational safety in industrial installations. The PVC insulation ensures long service life and resistance to environmental influences. The flame-retardant design reduces fire hazard during operation. The concentric conductor improves electrical conductivity and provides additional protection against contact voltage, which is particularly beneficial in power plants and switchgear installations. Installation is straightforward and does not require special tools, provided the bending radius requirements are observed.
