The cable of the brand VDE-Kabel, type NYY-J 4X10 RE, is a fixed installation power and control cable designed for use outdoors, in the ground, indoors, and in cable ducts. It is a copper earth cable with PVC insulation and a black PVC outer sheath, suitable for a wide range of electrical installations due to its construction and compliance with standards. The designation NYY-J indicates a cable with PVC insulation and protective sheath, where the letter J signifies the presence of a green-yellow protective conductor. The specification 4X10 RE means the cable has four conductors, each with a cross-section of 10 mm², with the conductors being round single-strand (RE). This design ensures high mechanical stability and is particularly suitable for permanent installations in the ground or in channels.

Applications
This cable is designed for use in various environments, including outdoor areas, underground installations, indoor spaces, and cable ducts. It is particularly suitable for applications requiring high mechanical and chemical resistance, such as in industry, construction, or infrastructure. Underground installation is safe and durable due to the robust PVC covering and the protective conductor configuration. Applications range from supplying machines and systems to powering lighting systems or control lines.

Functions and Equipment in Detail
The cable consists of bare copper conductors manufactured according to VDE 0295. The conductors are insulated with PVC, with conductor identification following VDE 0293-308. For up to five conductors, identification is done by color, with the green-yellow protective conductor (J) clearly identifiable. From six conductors onwards, a black conductor with white digits is used. A filler layer ensures even distribution of the conductors within the cable cross-section, enhancing mechanical stability. The black PVC outer sheath protects the cable from external influences such as moisture, mechanical stress, and UV radiation.

Technology Explained Simply
The rated voltage is 0.6/1 kV, meaning the cable is designed for electrical installations with an operating voltage up to 1 kV. The test voltage of 4 kV is used for quality control and ensures the cable shows no insulation faults even under increased voltage. The operating temperature is limited to a maximum of +70 °C, with installation allowed at temperatures from -5 °C to +70 °C. After installation, the cable can be operated at temperatures from -30 °C to +70 °C. The bending radius is 15 times the cable diameter for single-conductor lines and 12 times for multi-conductor lines, enabling flexible installation. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), ensures limited flame spread in case of fire.

Compatibility and Accessories
The cable is designed for use with standard installation techniques and materials. It can be connected using appropriate cable lugs, connection boxes, and other electrical components suitable for the rated voltage and cross-section. The use of protective conductors (J) enables compliance with VDE regulations for protective measures. The cable type is typically supplied on reels, with the length varying depending on the supplier.

Installation and Mounting
Installation requires compliance with applicable regulations, particularly VDE 0100 and VDE 0105. Underground installation should consider minimum depth and environmental conditions. Bending radii must be observed to ensure the mechanical integrity of the cable. Connections between conductors are made using suitable cable lugs or connection boxes, taking into account electrical and mechanical requirements.

Advantages in Operation
The cable offers high reliability and longevity due to its robust construction and use of high-quality materials. The PVC insulation and outer sheath protect the cable from environmental influences, ensuring a long service life and low maintenance requirements. The flame-retardant design increases operational safety, especially in enclosed spaces or installations with increased fire risk. Clear conductor identification simplifies installation and maintenance.
