Power cable YKY 4x70 SM 1kV G-116475

Energy cable YKY 4x70 – reliability and safety in your installation

Energy cable YKY 4x70 SM 1kV is a solid solution for transmitting electrical energy, designed for both permanent and underground installations. Made of copper, with PVC insulation and coating, it ensures safe and long-lasting operation. This cable is a combination of proven materials and construction that will meet the expectations of both professional installers and end users.

Construction and application

The YKY 4x70 cable consists of four copper cores with a cross-section of 70 mm², insulated with polyvinyl chloride (PVC). The whole is surrounded by an external PVC coating that protects against mechanical damage and weathering. The cores are identified by colors in accordance with HD 308 S2 standard, which facilitates their differentiation during installation. This cable is used in:

• electrical installations in residential and industrial buildings,
• electrical power distribution networks,
• underground installations (direct burial),
• connections of electrical devices requiring high current capacity.

Key features and benefits

• Copper cores with a large cross-sectional area (70 mm²): Ensure low resistance and minimize energy losses during power transmission. This translates to more efficient operation of the electrical installation.
• PVC insulation and coating: Guarantee good protection against moisture, chemicals and mechanical damage. PVC is a widely used material in power cables due to its insulating properties and durability.
• UV resistance: Allows the cable to be used in outdoor installations, exposed to sunlight without risk of material degradation.
• Compliance with PN-93/E-90401 standard: Confirms that the cable meets the required safety and quality standards.
• Flexible core construction (class 2): Facilitates installation and routing of the cable in tight spaces. The stranded core construction increases resistance to bending and vibration.
• Long-lasting operation: Thanks to high-quality materials and solid construction, the YKY 4x70 cable is characterized by a long service life, which translates into savings in the long term.
• Minimum bending radius: 369.6 mm - important when planning the cable route to avoid damage to the internal cores.

This cable is an investment in a safe and reliable electrical installation that will last for many years. Its technical parameters and solid construction make it an ideal choice for both demanding installers and conscious end users.
