Tensile Design of Drag Chain Cables for Petrochemical Applications

Key Technical Data

500MΩ
300/500V

Automatic equipment drag chain systems undergo high-frequency reciprocating bending. Conventional cables can only withstand slight bending, causing core wires to break and signals to be interrupted during long-term operation, resulting in a high equipment failure rate. To address this pain point, Shanghai Suoqi drag chain cables have been specifically optimized in both materials and processes: the conductors use VDE 0295 CLASS 6 ultra-fine copper wire strands, the insulation is made of a special PVC/elastomer compound, and the outer sheath is a PUR/TPU blend, with a bending cycle resistance of ≥10 million times. In actual applications, the product is recognized by customers in automation, drag chain, and production line fields for its bending resistance, high flexibility, and shielding performance. Customization according to drawings and direct shipment from stock are supported. For details, please contact 13311756197.

Frequently Asked Questions

What is the purpose of the shielding layer in a drag chain cable?

Tin-plated copper braided aluminum foil composite shielding suppresses electromagnetic interference, ensuring stable transmission of servo and encoder signals at high speeds.

How to assess the bending lifespan of drag chain cables?

Measured by the number of bending cycles, high-quality drag chain cables can reach more than 8 million cycles. When selecting, it is necessary to match the drag chain's travel, speed, and bending radius.
