Power cable YKY 0.6/1 kV 4×240 mm² YKY-4X240-1KV NYY

Power Cable YKY 4x240 SM – Reliable Power Supply for Diverse Applications

The YKY 4x240 SM power cable is a robust solution for electrical power transmission, suitable for both indoor and outdoor installations. Constructed with copper conductors of 240 mm² cross-section, insulated with polyvinyl chloride (PVC), it ensures safe and efficient operation in networks with a rated voltage up to 1 kV. The cable features four color-coded conductors, simplifying installation and connection.

The YKY cable offers high flexibility thanks to Class 2 stranded conductors, making it easy to install even in challenging conditions. The absence of armor and shielding makes the cable lighter and easier to handle—advantages appreciated by installers. The outer sheath made of PVC provides resistance to mechanical damage and environmental factors.

Key Features and Benefits

• Copper conductors with large cross-section (240 mm²): Enable high current transmission, essential for demanding applications.
• PVC insulation: Ensures excellent electrical insulation and moisture resistance.
• Four color-coded conductors: Facilitate correct connection and minimize installation errors.
• Class 2 stranded conductors: Enhance cable flexibility, easing handling and installation.
• Wide range of applications: Ideal for power lines indoors and outdoors, in cable ducts, and for direct burial in soil.
• Temperature resistance: Maximum allowable conductor temperature is 70°C, ensuring stable performance under varying environmental conditions.
• Minimum bending radius of 670.8 mm: Allows flexible routing without risking insulation damage.

Applications and Installation

The YKY 4x240 SM cable is suitable for:

• Electrical installations in residential and industrial buildings.
• Power supply lines for high-power equipment.
• Electrical distribution in urban infrastructure.
• Direct burial in soil.
• Installation in cable ducts.

Installation must be performed by a qualified electrician in accordance with applicable standards and safety regulations. Special attention must be paid to the minimum bending radius and correct connection of conductors according to their color coding. Due to the absence of shielding, this cable is not recommended for use in areas exposed to strong electromagnetic interference.

Compliant with EN 13501-6, the cable has a fire reaction class of Eca, indicating limited flammability and low smoke emission during fire. Note that the absence of armor also means no additional mechanical protection—when installing, avoid locations prone to physical damage.
