VDE-Kabel 248797 NYCWY 4x240 mm² SM / 120 mm² drum Eca PVC-insulated earth cable, concentric conductor content_copy

The cable NYCWY 4X240 SM/120 from VDE-Kabel 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 in installations where increased electrical and mechanical protection against contact voltage is required. The cable is designed for installation outdoors, in the ground, indoors, and in cable ducts, making it suitable for various industrial and infrastructural applications.

Applications
This cable is specifically designed for use in industrial environments where high mechanical loads and electrical safety requirements exist. It is commonly used in power plants, local network supply, and switchgear applications where reliable and durable cable routing is necessary. Installation takes place both in the ground and indoors, with the robust construction also suitable for outdoor use.

Functions and Equipment in Detail
The conductor is made of bare copper according to VDE 0295, with the configuration sector-shaped stranded (SM). This conductor design enables optimal space utilization within the cable cross-section and ensures even current distribution. The cores are insulated with PVC, with core identification according to VDE 0293-308. A filler layer ensures structural stability and prevents displacement of individual cores. A concentric conductor, made of bare copper wires, is helically stranded around the common core sheathing and supplemented by a counter-twist made of copper tape, providing additional protection against electrical interference and contact voltage. The outer sheath is made of black PVC, ensuring high mechanical and chemical resistance as well as good weather resistance.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for use in low-voltage networks. The test voltage of 4 kV serves safety testing and ensures the cable remains stable even under increased voltage. The operating temperature is limited to a maximum of +70 °C, with the cable tolerating temperatures from -5 °C to +50 °C during installation and from -30 °C to +70 °C after installation. The bending radius is 12 times the cable diameter, allowing flexible installation without compromising the cable’s mechanical integrity. The flame retardancy according to VDE 0472 T. 804, test method B (equivalent to IEC 332-1), ensures the cable does not ignite quickly in case of fire and does not propagate flames, enhancing safety during operation.

Compatibility and Accessories
The cable is suitable for use with standard cable connectors, cable lugs, and other connection elements designed for PVC-insulated cables with a cross-section of 240 mm². The use of a concentric conductor enables effective grounding and protective conductor function, which is particularly advantageous in switchgear and industrial installations. It is compatible with other cables of the NYCWY type, also intended for ground and indoor installations.

Installation and Mounting
Installation involves laying the cable in the ground, in cable ducts, or indoors. Outdoor installation requires careful planning of bending radii and mechanical loads. Underground installation should consider local conditions and required protective measures. Connection of the cable to devices or switchgear is made using appropriate cable lugs or cable connectors designed for a cross-section of 240 mm². The use of a concentric conductor requires proper grounding to ensure protective function.

Operational Advantages
The cable offers high mechanical strength and electrical safety, making it particularly suitable for demanding industrial environments. The PVC insulation and black-colored outer sheath provide high resistance to weather influences and chemical stress. Flame retardancy according to VDE 0472 T. 804, test method B, increases operational safety, especially in enclosed spaces or installations with increased fire risk. The sector-shaped conductor design enables compact installation and efficient use of the cable cross-section.
