The cable NYY-J 3X2.5 RE 100M from VDE-Kabel is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It is particularly suitable for applications requiring high mechanical and chemical resistance as well as secure electrical supply. The cable features a green-yellow protective conductor (J), making it suitable for use in electrical installations in accordance with VDE regulations. The designation RE indicates a round single-strand copper conductor manufactured according to VDE 0295, offering high mechanical strength and good conductivity.

Applications
This cable is intended for use in various environments, including underground installation, outdoor areas, indoor spaces, and cable ducts. It is especially suitable for installations requiring permanent and reliable power supply, such as in industry, construction, or building electrical systems. Installation must consider the specified temperature ranges: during installation between -5 °C and +70 °C, and after installation between -30 °C and +70 °C. The maximum operating temperature is +70 °C, ensuring safe operation under normal conditions.

Functions and Equipment in Detail
The cable construction includes bare copper conductors manufactured according to VDE 0295. The cores are insulated with PVC, ensuring high electrical insulation and mechanical stability. Core identification follows VDE 0293-308, with standardized color coding for up to five cores. The green-yellow protective conductor (J) is an integral part of the cable and serves electrical safety. A filler layer ensures even distribution of the cores and improves mechanical stability. The outer sheath is made of black PVC, which is UV-resistant and resistant to environmental influences.

Technical Explanation
The rated voltage of the cable is 0.6/1 kV, meaning it is suitable for applications with an operating voltage up to 1 kV. The test voltage of 4 kV serves safety testing and ensures the electrical strength of the insulating material. Flame retardancy according to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), means that the cable does not propagate flame during a fire test, thus presenting a low fire hazard. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core cables, enabling safe and damage-free installation.

Compatibility and Accessories
The cable is designed for use in electrical installations executed according to VDE standards. It can be used in combination with suitable cable lugs, junction boxes, and other connection elements designed for the respective voltage class and cross-section. The use of accessories not specifically designated for this cable type requires compatibility testing regarding mechanical and electrical requirements.

Installation and Mounting
Installation must comply with the specified temperature ranges and bending radii. The cable is intended for fixed installation and must not be moved or loaded after installation. Underground installation requires sufficient depth and protective measures against mechanical damage, such as cable protection conduits. Core connections must be made using suitable connection elements designed for a cross-section of 2.5 mm².

Operational Advantages
The cable offers high reliability and longevity due to the use of high-quality materials and compliance with standards. The PVC insulation and black-colored outer sheath provide high resistance to environmental influences. Flame retardancy increases operational safety, especially in enclosed spaces. Uniform core identification simplifies installation and maintenance.
