PUR cable for cable carriers acc. to UL/CSA HELUCHAIN® MULTIFLEX 512®-PUR UL/CSA 3G0,75 mm² grey, black cores numbered acc. to DIN VDE 0293-334 acc. to DIN VDE 0293-334 21571

Flexible cable for chain guides – reliability in harsh conditions

This high-quality flexible cable, catalog number 21571, is the ideal solution for applications requiring high mechanical and chemical resistance. The HELUKABEL MULTIFLEX 512-PUR cable is designed for use in dynamic systems such as chain guides, but will also perform well in many other industrial applications. Its construction and materials guarantee long-lasting and trouble-free operation even in extreme conditions.

Construction and properties

The cable is characterized by a cross-section of 0.75 mm² and three cores, making it suitable for transmitting control and power signals. It is made of high-quality materials: multi-strand copper conductors class 6 provide flexibility and resistance to bending, and polypropylene (PP) insulation protects against electrical damage. The outer jacket made of polyurethane (PUR) provides resistance to abrasion, cuts, oils, chemicals and UV radiation. Additionally, the cable is halogen-free, which increases safety in the event of a fire.

• Mechanical strength: The cable construction has been optimized for operation in chain guides, where it is exposed to continuous bending and friction.
• Chemical resistance: The PUR outer jacket provides resistance to a wide range of chemicals, including oils, acids, bases and solvents.
• Safety: The halogen-free construction minimizes the emission of toxic gases in the event of a fire.
• Flexibility: The multi-strand copper conductor class 6 provides high cable flexibility, making it easier to install and route.
• Wide temperature range: The cable retains its properties in a temperature range from -40°C to +90°C (flexible) and from -30°C to +80°C during installation.

Applications and standards

This cable is used in many industries, including:

• Industrial automation: For connections in machines and automation equipment.
• Robotics: For powering and controlling industrial robots.
• Oil and gas industry: As a control cable and instrumentation on drilling platforms and ships.
• Chemical industry: In environments exposed to aggressive chemicals.
• Outdoor installations: Due to its weather resistance, it can be used outdoors.

The cable meets the requirements of standards: UL/CSA (Style 21209), CSA C22.2 No. 210 and IEC/DIN EN 60332-1-2 (fire resistance). The outer diameter of the cable is 6.5 mm, which makes it easier to route through various cable ducts and chain guide systems. The rated voltage U is 600 V and the test voltage is as high as 3000 V, which confirms its high quality and safety of use.
