The NYY-J 4 mm² Underground Cable – Robust and Versatile for Direct Burial
The NYY-J 4 mm² is a high-quality power cable with PVC insulation and outer sheath, specifically designed for direct burial in the ground. It is perfect for both private and commercial outdoor applications, such as garden installations, construction sites, or industrial facilities. Thanks to its robust construction, it provides reliable protection against moisture, mechanical stress, and weather influences. Available in 3-core or 5-core versions, either by the metre or in convenient rings.
Advantages of NYY-J 4 mm² Underground Cable
- High Resistance: Protection against moisture, corrosion, rodents, and chemical influences in the soil.
- Mechanical Stability: Tough PVC sheath withstands pressure and ground movement – ideal for long-term installations.
- Versatile Installation: Can be laid directly in the ground, in concrete, in water, or on cable trays (in accordance with VDE standards).
- Safety: Integrated protective conductor (green-yellow in the -J variant), flame-retardant, and suitable for rated voltages up to 0.6/1 kV.
- Longevity: Temperature range from -40 °C to +70 °C – frost- and heat-resistant for decades of use.
- Easy Handling: Flexible to install, affordable prices, and high-quality copper for efficient power transmission.

Frequently Asked Questions About Underground Cable Installation (FAQ)
- How deep must an NYY-J underground cable be buried?
- At least 60 cm below the surface (in private areas); under paths or driveways 80 cm. Always use a 10 cm sand bed below and above the cable for optimal protection.
- Is a protective conduit required for NYY-J underground cable?
- No, NYY-J may be laid directly in the ground. However, a protective conduit (e.g., empty pipe) is recommended for additional mechanical protection and easier replacement later.
- Is the underground cable allowed to be laid in concrete or water?
- Yes, in concrete (except vibrated concrete) and in water, provided there are no strong mechanical stresses.
- Do I need a warning tape?
- Yes, place a red warning tape marked “Caution – Underground Cable” approximately 30 cm above the cable to protect against future excavation work.
- Which core count to choose: 3x4 mm² or 5x4 mm²?
- 3-core for simple power supply (e.g., a single socket), 5-core for three-phase current or parallel connections (e.g., lighting + socket).
