VDE-Kabel 247370 NYCY 3x1.5 mm² RE / 1.5 mm² Eca PVC-insulated earth cable, concentric conductor content_copy

The cable of type designation NYCY 3X1.5 RE/1.5 from VDE-Kabel is a fixed installation power and control cable, primarily used in industrial and switchgear installations as well as in power plants. It is particularly suitable for applications where enhanced mechanical protection against contact voltage is required. The cable features a concentric conductor, providing additional protection and increasing electrical safety. The construction is designed for underground installation, with an outer sheath made of black PVC that resists mechanical stress and environmental influences.

Applications
This cable is intended for use in industrial installations, switchgear, and power plants, where high requirements for electrical safety and mechanical robustness apply. It is especially suitable for applications requiring protection against contact voltage via a concentric conductor. Installation is carried out underground, with the cable structure meeting requirements for mechanical strength and electrical insulation.

Functions and Equipment in Detail
The conductor is made of bare copper according to VDE 0295, with the execution (RE) being round single-strand. The cores are insulated with PVC, with identification according to VDE 0293-308. For up to five cores, identification is by color; for seven or more cores, identification is 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 design ensures effective shielding and improved protection against contact voltage.

Technology Explained Simply
The rated voltage is 0.6/1 kV, indicating the maximum voltage at which the cable can be safely operated. The test voltage of 4 kV is used to verify insulation strength. The operating temperature is limited to a maximum of +70 °C, with the cable being installable at temperatures between -5 °C and +50 °C, and capable of withstanding temperatures from -30 °C to +70 °C after installation. The bending radius is 12 times the cable diameter, which must be considered during installation to avoid damage. 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.

Compatibility and Accessories
The cable is designed for use in industrial and power engineering installations, where it connects with other components such as switchgear, transformers, or electrical machines. It is equipped with a concentric conductor, enhancing electrical safety and reducing the risk of contact voltage. Use is in conjunction with suitable connection elements that meet the requirements of the specific installation.

Installation and Mounting
Installation is carried out underground, taking environmental conditions into account. The cable can be installed at temperatures between -5 °C and +50 °C. After installation, it must withstand temperatures from -30 °C to +70 °C. The bending radius is 12 times the cable diameter, which must be considered during planning. Installation is typically performed by qualified personnel who comply with technical specifications and safety requirements.

Operational Advantages
The cable provides high mechanical protection through the concentric conductor, reducing the risk of contact voltage. The PVC insulation and black-colored outer sheath ensure high mechanical strength and resistance to environmental influences. Flame retardancy according to VDE 0472 Part 804, test method B, increases safety in case of fire. The maximum operating temperature of +70 °C enables stable operation under normal operating conditions.
