PUR control and power cable, PURÖ-OZ 2x4 mm² grey, black numbered cores 22172

Flexible cable for demanding conditions

This 2x4 mm² flexible cable with a polyurethane (PUR) jacket is a solution for installations where mechanical and chemical resistance are important. Designed for use in harsh industrial environments, it is perfect for machines, construction, and installations exposed to oils and coolants. Its construction ensures reliability and long-term operation.

Construction and properties

The cable features multi-strand copper conductors (class 5), providing high flexibility and ease of installation. The PVC TI2 insulation is oil-resistant, and the outer polyurethane (PUR) jacket protects against abrasion, tearing, and weathering. The gray color (RAL 7001) facilitates identification. The conductors are numbered, simplifying installation work. A version without a protective conductor (OZ) is available.

Key features of the cable include:

• Wide temperature range: Operation at temperatures from -40°C to +80°C (stationary) and from -20°C to +80°C (flexible) guarantees reliability in various conditions.
• Chemical resistance: Special PVC TI2 insulation provides resistance to mineral oils and coolants, which is crucial in mechanical engineering.
• Mechanical strength: The polyurethane (PUR) jacket protects against abrasion and mechanical damage, ensuring a long cable life.
• Flexibility: The construction with multi-strand conductors makes it easy to lay the cable even in tight spaces.
• Compliance with standards: Meets the requirements of DIN VDE 0285-525-1 / DIN EN 50525-1 and has a CE certificate confirming compliance with the Low Voltage Directive 2014/35/EU.

Applications and technical parameters

This cable is used in:

• Mechanical industry: Ideal for connections in machines exposed to intensive use and contact with oils.
• Construction and installations: Excellent for connections in places requiring high mechanical and chemical resistance.
• Rolling mills and steelworks: Will perform well in harsh industrial conditions with high temperatures and exposure to chemicals.
• Outdoor installations: Can be used outdoors due to its weather resistance.

Technical specifications: The cable has a conductor cross-section of 4 mm², a rated voltage of 500 V, and an outer diameter of approximately 9.2 mm. The operating temperature range is from -40°C to +80°C for stationary operation and from -20°C to +80°C for flexible operation. The insulation resistance is at least 20 MOhm x km, and the minimum bending radius is 4 x outer diameter for fixed laying and 7.5 x outer diameter for flexible operation.
