VDE-Kabel NYCWY 4X35 RM/16 is a fixed installation power and control cable primarily used in industrial and switchgear applications, power plants, and local networks. It is designed for safe power transmission and control, particularly in environments requiring enhanced electrical and mechanical protection against contact voltage. The cable is suitable for outdoor installation, underground, indoors, and in cable ducts. It features a concentric conductor providing improved earthing and protection, and is equipped with a black PVC outer sheath resistant to mechanical and chemical stresses.

Applications
This cable is suitable for use in industrial plants, power supply networks, and switchgear where high reliability and safety are required. It is especially suited for outdoor and underground applications, where it is exposed to mechanical stress, moisture, and weather influences. Installation indoors and in cable ducts is also possible, with the flame-retardant design enhancing safety in enclosed spaces.

Functions and Features in Detail
The conductor is made of bare copper according to VDE 0295, with RM indicating round multi-strand. The cores are insulated with PVC and marked according to VDE 0293-308, enabling clear identification of individual cores. A filler layer ensures even distribution of cores within the cable cross-section. The concentric conductor consists of bare copper wires stranded helically around the common core insulation, supplemented by a counter-helix made of copper tape. This construction ensures efficient earthing and enhances electrical safety. The black PVC outer sheath protects the cable against mechanical stress and environmental influences.

Technical Explanation
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 ensures quality control and guarantees the cable remains stable under increased voltage. The operating temperature is limited to a maximum of +70 °C, with the cable tolerating installation temperatures from –5 °C to +50 °C and post-installation temperatures from –30 °C to +70 °C. The bending radius is 12 times the cable diameter, allowing flexible installation without damaging the cable. The flame-retardant property according to VDE 0472 T. 804, test method B (equivalent to IEC 332-1), means the cable is only limitedly flammable and does not propagate live flame, enhancing safety in enclosed spaces.

Compatibility and Accessories
Special accessories are available for connecting and protecting the cable, such as the VHR354 sleeve 35 mm² for compacted conductors made of E-Cu, galvanically zinc-plated. This sleeve is suitable for secure and durable connections of copper conductors and is used in electrical installations for connecting cables and conductors. Combining it with appropriate connection elements ensures a reliable electrical connection and prevents corrosion or contact loss.

Installation and Mounting
Installation involves laying the cable outdoors, underground, indoors, or in cable ducts. The laying must respect the bending radius of 12 times the cable diameter to avoid damage. Installation temperature conditions (–5 °C to +50 °C) and post-installation conditions (–30 °C to +70 °C) must be observed to ensure functionality and service life. The flame-retardant design requires no special installation measures, although compliance with VDE standards and safety regulations is recommended.

Operational Advantages
The cable offers high mechanical and electrical stability, increasing reliability in demanding environments. The flame-retardant design reduces fire risk and improves safety. The concentric conductor ensures efficient earthing and protects against contact voltage. The PVC insulation and outer sheath provide protection against moisture, mechanical stress, and environmental influences. The use of bare copper ensures high conductivity and low resistance, enhancing the efficiency of power transmission.
