Key Points for Selecting Drag Chain Cables for Rail Transit

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 issue, 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 blend, and the outer sheath is a PUR/TPU blend, with a bending cycle resistance of ≥10 million times. In actual applications, the product has been recognized by customers in CNC, drag chain, and CNC machine tool fields for its high flexibility, wear resistance, and tensile strength. Customization according to drawings and direct shipment of stock are supported. For details, call 13311756197.

Product Features

Durable Outer Sheath: The outer sheath is usually made of high-strength PUR material, which has good tensile strength and oil resistance. It can withstand a certain amount of tension and friction during the operation of CNC machines, while also resisting corrosion from oil and other substances, thereby improving the durability of the cable.

Good anti-interference capability: Uses a tinned copper wire braided shielding layer, which has a high shielding density, can effectively suppress electromagnetic interference, ensure the stability of signal transmission, prevent CNC machine tools from malfunctioning due to external electromagnetic interference, and help maintain machining accuracy.

Application Scenarios: Mainly suitable for drag chain systems of various types of CNC machine tools, such as lathes, milling machines, drilling machines, grinders, and machining centers. It can provide power transmission and signal control for motors, encoders, drivers, and other equipment in components such as spindle movement, table feed, and tool post movement of the machine tool, ensuring that cables can work stably during the machining process of CNC machine tools.

Frequently Asked Questions

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.

What should be considered when selecting drag chain cables?

Travel, speed, acceleration, bending radius, and oil resistance must be provided, with margins reserved for the most demanding conditions to avoid early failure.
