Automated equipment drag chain systems bend at high frequency and can only withstand minor bending. Long-term operation leads to core wire breakage and signal interruptions, resulting in a high equipment failure rate. Shanghai Suo Qi drag chain cables are specially designed for these working conditions. Core wire twist shielding and overall shielding (aluminum foil tin-plated copper braiding), with sheaths made of polyurethane material, suitable for high-frequency reciprocating bending conditions of drag chain tank chains. The cable features high flexibility, oxygen-free bare copper wire, tinned copper, and other characteristics, widely used in drag chains, servos, automation, and other fields. Shanghai Suo Qi Cable Direct from the source factory, customizing multiple cores and specifications on demand, with ample stock and nationwide shipping. Consultation hotline 13311756197.

Product Features

▍Shielding System: Layered protection, worry-free interference resistance. Power type: Single set of tin-plated copper wire braided shielding (density ≥85%), effectively suppressing electromagnetic interference. Composite type: Individual shielding of control cores. Overall shielding (divided main shielding structure), with crosstalk resistance increased to 95%, ensuring precise signal transmission.

▍Sheath System: Dual-material selection, suitable for all environments Conventional scenarios: Special modified elastomer sheath with a wear resistance coefficient of ≥120mg/1000 cycles, suitable for dry indoor environments; Harsh environments: PUR polyurethane sheath, oil-resistant (resistant to diesel soaking for 72h without corrosion), waterproof (IP67), UV aging resistant, suitable for outdoor, oily, and humid environments.

▍Structural Reinforcement: Dual-layer design, high-speed compatibility. The inner sheath uses armor-type extrusion technology, with a fixed stranded wire structure to prevent loosening; The outer sheath is high-pressure formed, with a surface friction coefficient of ≤0.3, supporting high-speed movement (acceleration ≥ 5m/s²), with a bending life of up to 10 million cycles.

▍Outdoor Complex Conditions Preferred configuration: PUR polyurethane sheath Partial Shielding Composite Type Applicable scenarios: port crane servo systems, chemical mixing equipment, requiring resistance to oil, water, and corrosion, bending service life of ≥ 8 million cycles.

▍High-speed, high-frequency operating conditions Preferred configuration: double-layer structure, tin-plated copper shielding composite type. Applicable scenarios: collaborative robot joints, high-speed packaging machines, movement speed ≥ 10m/s, acceleration ≥8m/s².

Application scenarios

5. Installation and Identification Guide ▍Core Wire Identification System Power supply core: black body with white numeric codes (1-4), standard yellow/green dual-color grounding core; Control core: colored twisted (such as red/white, blue/white), compliant with DIN 47100 standard, supports color code customization. ▍Installation Operation Points Twisted laying is prohibited; the cable reel must be unfolded at a constant speed from the center; Cable spacing inside drag chains ≥ 15% diameter; separators are recommended; In high-speed scenarios, fixed at both ends and middle points of drag chains, fixed spacing ≤500mm; Avoid contact with sharp components; bending paths should reserve ≥10% redundant length. 6. Typical Application Scenarios Industrial Robots: Six-axis robot drag chain system, supports 360° rotation and bending, transmits power and encoder signals; Intelligent logistics equipment: AGV cart with servo motor connection, roll-resistant and dragging-resistant, suitable for 24-hour continuous operation; New Energy Equipment: Servo roller equipment for lithium battery production lines, resistant to electrolyte corrosion, with a bending lifespan of ≥ 10 million cycles; High-end machine tools: Five-axis machining center servo axis drag chain, with total shielding design ensuring nanometer-level control signal accuracy.

Frequently Asked Questions

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.

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.
