Power cable YKY 4x50 SM 1kV G-116473

Energy cable YKY 4x50 SM – reliability and safety in your installation

The YKY 4x50 SM cable is a solid choice for demanding electrical installations. Designed for transmitting energy in circuits with a rated voltage of 1 kV, it is perfect for both permanent and underground installations. Made of copper, with insulation and a polyvinyl chloride (PVC) coating, it provides durability and resistance to mechanical damage.

Construction and application

The YKY cable consists of four cores with a cross-section of 50 mm², allowing for the transmission of significant currents. The sector-shaped cores facilitate cable laying, and the color-coded cores simplify installation work. This is a universal cable with applications in:

• Electrical installations in residential and industrial buildings.
• Energy distribution in distribution networks.
• Connections of electrical devices requiring a large conductor cross-section.
• Underground installations – the cable is adapted for direct burial.

Key features and benefits

• Durable construction: Copper cores and PVC insulation and coating guarantee long-lasting and trouble-free operation of the cable.
• Resistance to external conditions: The cable is resistant to UV radiation, allowing it to be used in outdoor installations. The permissible temperature range during installation is -5°C to +50°C, and after installation (without vibration) -30°C to +50°C.
• Safety of use: The cable has a fire reaction class of Eca, which ensures limited flammability in the event of a fire. Complies with the requirements of PN-93/E-90401 standard.
• Easy installation: Color-coded cores and sector shape facilitate and speed up installation work. The minimum bending radius of 330 mm allows for flexible cable routing.
• High mechanical strength: Thanks to the use of copper as a conductive material and a solid outer coating, the cable is resistant to mechanical damage during transport, installation and operation.
• Conductor resistance: Conductor resistance at 20°C is 0.387 Ohm/km, which minimizes energy losses during current transmission.

The YKY 4x50 SM cable is an investment in a safe and reliable electrical installation that will last for years. Its solid construction and resistance to external conditions make it an ideal choice for both professionals and end users.
