Installation Cable NKT Cables YDY-ŻO 5x4.0 mm² 750V, PVC insulated conductor

NKT Cables YDY-ŻO 5x4.0 mm² 750V is a fixed-installation multicore power cable intended for indoor electrical wiring. The cable contains five copper conductors with a cross-section of 4.0 mm² each, PVC insulation around each conductor and a PVC outer sheath. It is designed for permanent installation in conduit, ducting, cable trays or on fixed routes in residential and commercial buildings and is suitable for lighting circuits and general power distribution at a rated voltage of 750 V.

Advantages

The construction of NKT Cables YDY-ŻO 5x4.0 mm² combines flexible stranded copper conductors and PVC insulation to provide reliable electrical continuity and mechanical protection for indoor fixed installations. Its five-core configuration simplifies multi-conductor runs where an earth and multiple phase or switched conductors are needed. The PVC sheath is resistant to normal indoor conditions and provides a consistent, compact cable profile for routing in conduits and trays.

Suitable for

• Fixed internal wiring in residential buildings
• Lighting circuits and switched power runs
• Power distribution to sockets and small appliances in commercial premises
• Installation in conduit, cable ducts or on cable trays

When it may not be suitable

This cable is intended for indoor fixed installations and is not suitable for direct burial in the ground, permanent outdoor exposure without additional protective measures, or installation in locations requiring halogen-free or low-smoke fire performance. It is also not recommended for use in environments requiring special chemical resistance or very high mechanical abuse protection unless additional protective conduits or trays are provided.

Key specifications

• Conductors: 5 copper cores, stranded
• Conductor cross-section: 4.0 mm² per core
• Insulation: PVC around each conductor
• Sheath: PVC outer sheath
• Rated voltage: 750 V
• Intended use: indoor fixed installation, conduit, cable tray

How to use

Plan the routing and calculate conductor sizes according to local electrical regulations and current-carrying capacity requirements. Cut the cable to length and strip the outer sheath and individual conductor insulation with appropriate tools, taking care not to damage the conductors. Connect the conductors to terminals or distribution blocks using correct torque and secure earthing where required. Install the cable in conduit, ducts or trays, support it at suitable intervals and avoid sharp bends that exceed the cable's minimum bending radius. Follow applicable national wiring rules and safety practices during installation and testing.

What to consider before purchase

• Verify that indoor PVC-sheathed cable meets the regulatory requirements for your country or project.
• Confirm conductor size (4.0 mm²) and five-core configuration match the circuit and load requirements.
• Ensure rated voltage (750 V) and insulation type are appropriate for intended application.
• Plan for additional protection if installation environment requires halogen-free, UV-resistant, or burial-rated cable.

Usage recommendations

Use NKT Cables YDY-ŻO 5x4.0 mm² for indoor fixed power and lighting installations where a five-core supply is required. When installing, adhere to local wiring regulations, protect the cable from mechanical damage, and size circuit protection devices according to conductor cross-section and installation method.
