Shanghai Suoqi Cable Co., Ltd. has long been specialized in the field of special flexible cables. Below is a professional interpretation of drag chain cable from three dimensions: material structure, performance advantages and application scenarios.
1. Material and Structural Parameters
Highly flexible servo drag chain cable — specially designed for mobile servo motor systems with drag chains, integrating highly flexible structure and composite function design, meeting stable power and control signal transmission in reciprocating bending and moving scenarios, adaptable to multiple working conditions.
1. Dual-structure design covering diverse needs — Power type (four-core independent structure): Core specifications: 4×0.5/0.75/1.0/1.5/2.5/4/6/10/16/25/35mm² (customized on demand); Functional positioning: single transmission of servo power supply, suitable for conventional automation equipment power connections.
Power + control composite type (integrated twisted structure): Innovative combination: 4 power cores + 1~2 groups of control cores (twisted into bundles); Typical specifications: ▪ 4G1.5+2×0.5 | 4G2.5+2×0.75 (power + single control group) ▪ 4G1.5+2×(2×0.5) | 4G2.5+2×(2×0.5) (power + double control groups); Scenario value: simultaneously completes power supply and control signal transmission, reducing wiring complexity, suitable for highly integrated servo systems.
2. Five core technology breakthroughs — Conductor process: ultra-fine stranding, flexibility upgrade: VDE 0295/CLASS 6 ultra-fine oxygen-free bare copper wire (diameter ≤0.1mm), multi-strand finely stranded into bundles, conductor flexibility improved by 40%, tinned copper conductor can be customized to enhance oxidation resistance.
Insulation solution: high-strength elastomer, double guarantee: special blended elastomer insulation material, dielectric strength ≥20kV/mm, mechanical tensile strength ≥15MPa, balancing electrical insulation stability and bending fatigue resistance.
Shielding system: layered protection, worry-free anti-interference: Power type: single group of tinned copper wire braid shielding (density ≥85%), effectively suppressing electromagnetic interference; Composite type: separate shielding of control cores + overall shielding (separate-total shielding structure), anti-crosstalk capability increased to 95%, ensuring precise control signal transmission.
Sheath system: dual material selection, full environment adaptation: Conventional scenarios: specially modified elastomer sheath, wear coefficient ≥120mg/1000 times, suitable for indoor dry environments; Harsh scenarios: imported PUR polyurethane sheath, oil resistant (no corrosion after 72h diesel soaking), waterproof (IP67), UV aging resistant, adapting to outdoor/oily/humid environments.
Structural reinforcement: double sheath design, high-speed compatible: The inner sheath adopts armor-type extrusion process to fix the stranding structure and prevent loosening; the outer sheath is high-pressure molded, with surface friction coefficient ≤0.3, supporting high-speed movement (acceleration ≥5m/s²), with bending life up to 10 million times.
3. Quick overview of key performance parameters: Basic value / Customized upgrade: Rated voltage: power cores 600/1000V, control cores 250V AC; higher voltage levels can be customized; Bending radius: mobile installation 7.5×D, fixed installation 5×D (D = outer diameter); minimum 5×D (special process); Ambient temperature: -40℃~+90℃; -60℃ low temperature / -120℃ high temperature customization; Shielding effectiveness: power type ≥60dB. Bending frequency ≤5 times/second.
Outdoor complex working conditions: Preferred configuration: PUR polyurethane sheath + separate-total shielding composite type; Applicable scenarios: port crane servo systems, chemical mixing equipment, requiring oil/water/corrosion resistance, bending life ≥8 million times.
