The copper earth cable NYY-J 12X1.5 RE from Faber 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 suitable for applications requiring reliable and durable power supply or signal transmission, particularly in industrial, commercial, or municipal installations. The cable features a black-coloured PVC outer sheath that resists mechanical stress and environmental influences such as moisture or UV radiation. The conductors are insulated with PVC and marked according to VDE 0293-308, with marking from six conductors onwards being black with white digits. Type J indicates the version with a green-yellow protective conductor, which is required for electrical safety during operation.

Applications
This cable is suitable for use in underground installations, outdoor environments, and indoor spaces where high mechanical and chemical resistance is required. It can be installed in cable ducts and is intended for use in buildings, industrial facilities, street lighting, or agricultural installations. Installation must consider the specified temperature ranges, which range from -5 °C to +70 °C during installation, and from -30 °C to +70 °C during operation. The maximum operating temperature is +70 °C.

Functions and Equipment in Detail
The conductor is made of bare copper, manufactured according to VDE 0295, and is in the RE (round single-strand) configuration. This construction ensures high mechanical strength and low elongation, providing stable installation and long-term operational reliability. The conductors are insulated with PVC, offering good insulation performance and resistance to moisture. The filler layer ensures even distribution of the conductors within the cable cross-section and prevents displacement. The black PVC outer sheath protects the cable from external influences such as mechanical stress, moisture, and UV radiation.

Technology Explained Simply
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 is used for quality testing and ensures the cable does not exhibit insulation faults even under increased voltage. Flame retardancy according to VDE 0472 Part 804, test method B (equivalent to IEC 332-1), guarantees that the cable is not self-igniting in case of fire and does not propagate flames. The bending radius is 15 times the cable diameter for single-core conductors and 12 times for multi-core cables, which must be considered during installation to avoid damage.

Compatibility and Accessories
The cable is designed for use in electrical installations executed according to applicable standards for underground installations and indoor installations. It can be combined with other cables of types NYY, NYKY, NYZG2Y, or NYYÖ, provided technical requirements such as voltage, cross-section, and protection class are matched. Use requires compliance with VDE standards and adherence to prescribed installation conditions.

Installation and Mounting
Installation must consider the specified temperature ranges and bending radius. The cable is designed for fixed installation and is not suitable for movable applications. Installation requires compliance with applicable regulations, particularly VDE 0100 and VDE 0105, as well as local building regulations. Underground installation requires sufficient depth and protective measures against mechanical damage.

Operational Advantages
The cable offers high operational reliability through the use of copper conductors and PVC insulation. Flame retardancy increases safety in case of fire. The use of a green-yellow protective conductor (Type J) ensures electrical safety and complies with regulations for protection against electric shock. High mechanical strength and resistance to environmental influences ensure long service life and low maintenance requirements.
