Highly Flexible Cables for Drag Chain Systems and Open Installation
HELUKABEL has control and drive cables in its portfolio that combines TC-ER-compliant flame retardancy and flexibility for moving applications in the drag chain.
Less installation time and lower costs: In many cases, the open installation of electrical cables without a conduit or closed cable duct offers significant advantages to the user. However, this is not always possible without the appropriate approval: In the USA, for example, cables must have a TC-ER (Tray Cable - Exposed Run) certification in order to be laid on a cable tray. In order to obtain this, both the materials used and the construction have to meet special requirements - including flame retardancy.
However, the increased flame retardancy required for TC-ER cables often comes at the expense of flexibility. As a result, the constant movement that occurs, particularly in cable carrier applications, is too much for most cables. The result is reduced durability and the risk of cable breakage, which can lead to costly downtime.

Thanks to their TC-ER approval, the PVC control cables MULTIFLEX 600 and MULTIFLEX 600-C are suitable for laying open and unprotected on the cable tray up to the machine.

The TOPSERV 600 VFD and TOPSERV 650 VFD drive cables are ideal as supply cables for servo motors.
For scenarios that necessitate both TC-ER-compliant flame retardancy and a high degree of flexibility, HELUKABEL boasts two optimal solutions in its portfolio: PVC control cables MULTIFLEX 600 (unshielded) and MULTIFLEX 600-C (shielded). Thanks to their TC-ER approval, these cables are suitable for laying open and unprotected on the cable tray up to the machine. They are appropriately designed as permanently moving connecting cables in drag chains for industrial machines and systems, with a minimum bending radius of 7.5 or 10 times the cable diameter. Additionally, the MULTIFLEX cables demonstrate exceptional oil resistance and, in the shielded version, excellent electromagnetic compatibility (EMC).
The TOPSERV 600 VFD and TOPSERV 650 VFD drive cables possess TC-ER approval and exceptional flexibility, making them ideal as supply cables for servo motors. Furthermore, a shield with a tinned copper braid offers substantial protection against electrical interference. Additionally, the special TPE sheath exhibits high resistance against oil and coolants, as well as abrasion, making it perfect for industrial applications in drag chain systems or with open installations.
Both the MULTIFLEX and TOPSERV cables have been available from HELUKABEL since 2016. They have demonstrated their suitability in various applications with different demands. This offers machine manufacturers producing for the American market a dependable solution that conforms to international standards. Together with its customers, HELUKABEL also develops individual solutions for special applications, ranging from tailor-made cables to completely pre-assembled and ready-to-install drag chain systems.
