Underground Cable NYY-J – Reliable Power Distribution for Direct Burial & Outdoor Use
NYY-J underground cables (also called Erdkabel or power cables) are robust, low-voltage (0.6/1 kV) PVC-insulated and sheathed cables designed for fixed installations, including direct burial in the ground, outdoors, in concrete, or even underwater without additional protection. Manufactured to German VDE standards (e.g., VDE 0276-603, DIN VDE 0250), NYY-J features copper conductors and includes a protective earth conductor (green-yellow, "J" suffix = "mit Schutzleiter"), making it the standard choice for safe power distribution in residential, commercial, industrial, and construction projects across Europe.
What is NYY-J Cable? Key Features & Benefits
- With protective conductor (J): Includes bare/green-yellow earth wire for enhanced safety (unlike NYY-O without ground).
- Direct burial approved: UV-resistant, moisture-proof black PVC sheath protects against mechanical stress, water, and environmental factors.
- Flame retardant: Meets IEC/EN 60332-1-2 / VDE 0482-332-1-2.
- Temperature range: Fixed: -40°C to +70°C; Installation: -5°C to +50°C (some variants -30°C to +70°C).
- Voltage rating: U0/U 0.6/1 kV; Test voltage 4 kV.
- Conductor options: Solid (RE/Class 1) or stranded (RM/Class 2) bare copper.
Common applications include outdoor lighting, machinery power supply, solar systems, building sites, switchgear, and underground distribution in gardens, industrial plants, or commercial properties. NYY-J offers excellent value for reliable, long-term performance without armouring.

Frequently Asked Questions about NYY-J Underground Cables
What is NYY-J cable?
NYY-J is a type of low-voltage (0.6/1 kV) power cable designed for underground installation, also known as Erdkabel in German-speaking regions. It features PVC insulation and sheathing, copper conductors, and includes a protective earth conductor (green-yellow, denoted by the "J"). This makes it ideal for direct burial without additional conduits, offering resistance to moisture, mechanical stress, and environmental factors. NYY-J complies with standards like VDE 0276-603 and IEC 60502-1 for reliable performance in fixed installations.
What is the difference between NYY-J and NYY-O cables?
The main difference is the protective conductor: NYY-J includes a green-yellow earth wire for enhanced safety in applications requiring grounding, such as residential or commercial power distribution. NYY-O lacks this earth conductor and is suited for systems where grounding is handled separately. Both share similar PVC construction and are suitable for underground use, but NYY-J is more versatile for standard European installations. Check our NYY-O page for alternatives.
What are the key specifications of NYY-J cables?
NYY-J cables have a voltage rating of 0.6/1 kV, with test voltage up to 4 kV. Conductor types include solid (RE/Class 1) or stranded (RM/Class 2) bare copper. Temperature ranges: -40°C to +70°C (fixed), -5°C to +50°C (installation). They are flame-retardant per IEC 60332-1-2 and available in multi-core configurations (e.g., 3x, 5x) with cross-sections from 1.5 mm² to 50 mm² or more. Outer sheaths are black PVC for UV and water resistance.
Where can I use NYY-J underground cables?
NYY-J is perfect for outdoor and underground applications like power supply to buildings, gardens, industrial sites, solar panels, outdoor lighting, machinery, and construction projects. It's approved for direct burial in soil, concrete, or even underwater (without mechanical protection), making it a go-to for reliable, long-term power distribution in Europe.
How do I install NYY-J cables underground?
Installation is straightforward: Dig a trench at least 60–80 cm deep (per local regulations), lay the cable on a sand bed for protection, cover with warning tape, and backfill. No additional conduits are needed due to its robust sheathing, but avoid sharp bends (min. radius 12x diameter). Always follow VDE 0100 guidelines and consult a certified electrician.
