NYY-J 3×1.5 mm² Underground Cable – Robust Power Cable for Direct Burial and Outdoor Installation
The NYY-J 3×1.5 mm² underground cable is a robust and versatile power cable designed for fixed electrical installations in indoor and outdoor areas. Its durable black PVC outer sheath makes it particularly suitable for installations exposed to moisture, weather conditions and moderate mechanical stress.
The NYY-J cable is suitable for direct burial in the ground, making it ideal for the permanent power supply of outdoor installations, garden buildings, lighting systems, pumps, electrical heating systems and other permanently installed electrical equipment. It can also be used as a supply cable for frost protection systems, outdoor surface heating or pipe trace heating, provided that the conductor cross-section is adequately dimensioned for the respective connected load.
The three solid copper conductors each have a cross-section of 1.5 mm². In addition to the live conductor and neutral conductor, the NYY-J cable includes a green-yellow protective conductor. The individual conductors are insulated with durable PVC and enclosed by an additional filling compound and a black PVC outer sheath.
With a rated voltage of 0.6/1 kV, the underground cable is suitable for a wide range of applications in building installations, power distribution and outdoor areas. It can be permanently installed in dry, damp and wet environments. Unlike flexible connection cables, the NYY-J cable is intended exclusively for fixed installations.
The underground cable is available in selectable lengths from 5 to 100 metres. This allows the required cable length to be selected according to the individual installation project without having to purchase a complete cable drum.
