HELUCHAIN TOPSERV: New Servo Cables for Drag Chains
HELUKABEL is expanding its HELUCHAIN cable portfolio for highly dynamic drag chain applications. With the HELUCHAIN TOPSERV 201 PVC UL/CSA and HELUCHAIN TOPSERV 211 PUR UL/CSA, we are introducing two high-quality servo cables designed for long-travel, sliding applications such as material handling and port systems. Users can choose between two jacket materials tailored to the demands of different applications and operating environments.
The HELUCHAIN TOPSERV 201 PVC UL/CSA and HELUCHAIN TOPSERV 211 PUR UL/CSA are designed for connecting servo motors in drive systems. These orange servo cables include an additional shielded twisted pair for motor temperature monitoring or brake control. With a minimum bend radius of just 7.5 × d (outer diameter), they deliver exceptional flexibility for highly dynamic drag chain applications.
Users can choose between two outer jacket materials. The cost-effective PVC option offers high durability under continuous movement, while PUR is ideal for applications requiring oil resistance, low-temperature performance, or halogen-free materials. Both versions feature shielding with 85% coverage and a flat braid angle to minimize electromagnetic interference (EMI).
One key factor behind the durability of these cables is their pressure-extruded inner jacket. This construction fills the gaps within the stranding, precisely guiding the conductors along the cable length while maintaining stable contact of the overall shield during bending. As a result, HELUCHAIN TOPSERV cables can withstand millions of bend cycles in real-world operation—even in extreme applications.
The HELUCHAIN TOPSERV 201 PVC UL/CSA and HELUCHAIN TOPSERV 211 PUR UL/CSA are available with power conductor cross sections ranging from 1.5 to 6 mm². These robust servo cables deliver long-lasting durability and help ensure reliable machine and plant operation—even under demanding motion conditions.
