PUR cable for cable carriers acc. to UL/CSA HELUCHAIN® MULTIFLEX 512®-PUR UL/CSA 12G2,5 mm² grey, black cores numbered acc. to DIN VDE 0293-334 acc. to DIN VDE 0293-334 21614

Flexible cable for chain guides – reliability in harsh conditions

This multi-core flexible cable, catalog number 21614, is a solution designed for demanding industrial and other applications. The HELUKABEL MULTIFLEX 512-PUR UL/CSA cable, made of high-quality materials, ensures reliable operation even in extreme conditions. Its construction and properties make it ideal for use in moving parts of machines, robotics, and the oil and gas sector.

Construction and properties

The cable is characterized by a solid construction. It is made of 12 multi-wire copper conductors with flexibility class 6 (according to DIN VDE 0295/IEC 60228), which guarantees high flexibility and resistance to material fatigue during repeated bending. The conductors are insulated with special PP, and their color – black with white numbers – facilitates identification. Additionally, the cable has a yellow-green protective conductor (in the version with a protective conductor), placed in the outer layer of the core. The whole is surrounded by a durable polyurethane (PUR) coating, resistant to abrasion, cuts, tearing and wear. The outer diameter of the cable is approximately 16.9 mm.

It is worth noting a number of important properties:

• Chemical resistance: the cable is resistant to oils, UV radiation, ozone, weathering, hydrolysis and many chemicals (acids, alkalis, lubricants).
• Halogen-free: the materials used do not contain halogen, which increases safety in the event of a fire and minimizes the emission of toxic gases.
• Temperature range: the cable retains its properties over a wide temperature range – from -40°C to +80°C during stationary operation and from -30°C to +90°C during flexible operation.
• Approvals and standards: the cable has UL/CSA certificates confirming its compliance with demanding safety and quality standards. It meets IEC 60332-1-2 and UL VW-1/CSA FT1 standards regarding fire resistance.

Applications and benefits

This cable finds wide application in industry:

• Machines and equipment: ideal for connections in moving parts of machines and equipment, robotics and cable management systems (energy chains).
• Oil and gas sector: it works perfectly as a control and instrumentation cable on drilling platforms, ships and in chemical and petrochemical plants – thanks to its resistance to drilling fluids (according to NEK TS 606).
• Outdoor installations: possibility of use outdoors thanks to weather resistance.

Thanks to its construction and properties, this cable ensures long-lasting and reliable operation in harsh industrial conditions. The low adhesion of the PUR coating makes it easier to route the cable in cable guides and minimizes the risk of mechanical damage. The conductor cross-section of 2.5 mm² allows for safe transmission of electrical energy with a rated voltage of up to 600V (UL: 1000V AC).
