Power cable YKY 0.6/1 kV 4×120 RMC YKY-4X120-1KV NYY

Power cable YKY – a reliable choice for above-ground and underground installations

The YKY 4x120 mm² power cable is a robust solution for permanent energy transmission in both above-ground and underground installations. Made of copper with PVC insulation and outer sheath, it ensures safe and long-term operation. This cable is particularly recommended for applications requiring high mechanical and chemical resistance.

Construction and characteristics

The YKY cable features a round cross-section with four conductors of 120 mm² each. Class 2 stranded conductors, twisted together, provide flexibility and ease of installation. Color-coded conductor identification simplifies correct connection. The durable PVC outer sheath protects against mechanical damage, moisture, and atmospheric influences. The absence of armor makes the cable relatively lightweight and easy to route. Note that the minimum bending radius of 547.2 mm must be observed during permanent installation – this is critical for maintaining its electrical and mechanical properties.

Applications and benefits

The YKY 4x120 mm² cable is widely used in:

• Above-ground installations: Direct burial in soil (in accordance with manufacturer recommendations).
• Underground installations: Cables laid on routes where there is no risk of mechanical damage.
• Power distribution: Transmission of electrical energy in distribution networks.
• Industrial installations: Supplying machinery and equipment requiring high power consumption.
• Construction: Power supply for buildings and structures.

Key advantages to note:

• Durability: Copper conductors ensure high conductivity and corrosion resistance.
• Safety: Rated voltage of 1 kV guarantees safe operation in most applications.
• Flexibility: Stranded conductor construction facilitates installation even in challenging conditions.
• Resistance to environmental factors: PVC sheath protects against moisture, chemicals, and UV radiation (to a limited extent).
• Compliance with standards: Fire reaction class Eca ensures basic fire safety performance (according to EN 13501-6).
