Drag chain cable popular science

Drag chain cable, as the name suggests, is a special cable installed and used inside the drag chain. In cases where equipment units need to move back and forth, to prevent cable entanglement, wear and tear, pulling off, hooking, and scattering, the cable is often placed inside a drag chain to protect the cable and allow the cable to move back and forth along with the drag chain. This kind of highly flexible special cable that can move back and forth with the drag chain without easy wear and tear is called a drag chain cable.

Special requirements for drag chain cable

In general, drag chain environments require drag chain cables to have the following characteristics:

  • Bending resistance: Drag chain cables must be able to withstand the bending pressure they experience in a U-shaped drag chain.
  • Mobility: Drag chains move back and forth when equipment is in operation, which in turn moves the drag chain cable back and forth.
  • Wear resistance: Drag chains are chain-like structures, and the movement of the drag chain cable is subject to friction from the chain. Therefore, the outer sheath of the drag chain cable must be wear-resistant.
  • High flexibility: The bending resistance, mobility, and wear resistance of drag chain cables require them to have a high degree of flexibility.
  • Other properties: Drag chain cables are used in complex and changing environments. Different equipment has different environmental requirements. Drag chain cables must not only have the special properties mentioned above, but also meet the specific requirements of different environments, such as oil resistance, cold resistance, water resistance, and radiation resistance.

Market analysis of drag chain cables

Drag chain cables are mainly used in industrial electronic systems, automatic generation lines, warehousing equipment, robots, fire systems, cranes, CNC machine tools, and the metallurgical industry. With the continuous decline of the consumer cable market, many manufacturers are turning their attention to the main cable market for automated equipment, the drag chain cable market. The fierce competition in the industry market has already become increasingly intense, and the cutthroat price competition in the industry.

Special drag chain cable requirements for professional manufacturers

To meet the continuous back-and-forth movement, drag chain cables generally consist of several components:

  • Copper wire structure
  • Core wire insulation
  • Tensile center
  • Twisted wire
  • Shielding
  • Outer sheath

For drag chain cables, each component must be carefully designed and chosen to ensure the cable’s flexibility, bending resistance, wear resistance, and other necessary properties.


Drag chain cables play a crucial role in industrial applications by providing flexible, durable, and high-quality electrical connections within drag chains. Professional manufacturers need to meet the specific requirements of drag chain cables to ensure optimal performance and longevity in various industrial environments.
