The product is an aluminium earthing cable of type NAYY-O 1X150RM, manufactured by VDE-Kabel. It is an energy and control cable designed for use outdoors, in the ground, in power plants, industrial and switchgear installations, as well as in local networks. The cable is also suitable for use in water, in dry and damp indoor areas, and in cable ducts, provided no mechanical damage is expected. The designation NAYY-O refers to a cable with PVC insulation and outer sheath, without an integrated protective conductor (O = without protective conductor), with the conductor made of aluminium.

Applications
This cable is designed for a wide range of applications in the field of energy and control technology. It is particularly used in underground installations, for example, in the supply of industrial plants, power stations, or local networks. Use in water and in cable ducts is also intended, provided mechanical stress is limited. The applications include both indoor and outdoor environments, provided that temperature and environmental conditions do not exceed the maximum operating limits.

Functions and Equipment in Detail
The conductor is made of aluminium and complies with standard VDE 0295. The core insulation is made of PVC, and the core identification follows VDE 0293-308. The cable features a filler layer that holds the individual cores together. The outer sheath is also made of PVC and is black in colour. The designation O in the type designation indicates that no protective conductor is integrated.

Technology Explained Simply
The rated voltage of the cable is 0.6/1 kV, which is sufficient for most industrial and energy applications. The test voltage is 4 kV, highlighting the electrical strength of the insulating material. The maximum operating temperature is +70 °C, and during installation, the cable can withstand temperatures from -5 °C to +50 °C. After installation, it can be exposed to temperatures from -30 °C to +70 °C. The bending radius is 12 times the cable diameter, which must be considered during installation to avoid damage. The flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), meaning that the cable does not propagate flames during a fire test and thus presents a limited fire hazard.

Compatibility and Accessories
The cable is suitable for use in existing and new installations in the field of energy supply and control technology. It can be used in combination with other cables of type NAYY, particularly in underground installations. Compatibility with other systems depends on the respective connection and joining techniques, which must be specified for each individual project.

Installation and Mounting
Installation requires adherence to the specified bending radii, which must be at least 12 times the cable diameter. The cable is installed in the ground, in cable ducts, or outdoors, with ambient temperatures during installation ranging from -5 °C to +50 °C. After installation, the cable is designed for temperatures from -30 °C to +70 °C. Installation is typically carried out without additional protective measures, provided no mechanical stresses are expected.

Advantages in Operation
The cable offers high electrical conductivity due to the aluminium conductor and good mechanical stability due to the PVC outer sheath. The flame retardancy according to VDE 0472 Part 804, test method B, increases operational safety. The use of PVC as insulating and protective sheath ensures high chemical resistance and weather resistance, extending the cable’s service life. Installation in the ground or in cable ducts enables discreet and secure installation, particularly in industrial environments.
