Product reference: Servo cable _ Servo drag chain cable
1. Materials and Structural Parameters
Highly flexible servo drag chain cable, specially designed for mobile servo motor systems with drag chains, integrating high flexibility structure and composite functional design, meeting stable transmission of power and control signals in cyclic bending and moving scenarios, suitable for various working conditions.
1. Dual-structure design to cover 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 (customizable on demand) Functional positioning: Single transmission servo power supply, suitable for power connection of conventional automation equipment.
▍Power and Control Composite Type (Integrated Twisted Structure) Innovative Combination: 4 power cores 1~2 sets of control cores (twisted into bundles) Typical Specifications: ▫ 4G1.5 2×0.5 | 4G2.5 2×0.75 (Power with single control set) ▫ 4G1.5 2×(2×0.5) | 4G2.5 2×(2×0.5) (Power with double control sets) Scenario Value: Simultaneously provides power supply and control signal transmission, reduces wiring complexity, suitable for highly integrated servo systems.
2. Five Major Core Technology Breakthroughs ▍Conductor Technology: Ultra-Fine Precision Stranding, Flexible Upgrade Using VDE 0295/CLASS 6 ultra-fine oxygen-free bare copper wire (diameter ≤ 0.1mm), stranded into bundles with multiple strands, the conductor's flexibility is increased by 40%, and tinned copper conductors can be customized to enhance oxidation resistance.
▍Insulation solution: High-strength elastomer for dual protection. Special hybrid elastomer insulation material with dielectric strength ≥ 20kV/mm and mechanical tensile strength ≥15MPa, balancing electrical insulation stability and flexural fatigue resistance.
▍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 Options, Suitable for All Environments Normal Conditions: Specially modified elastomer sheath, abrasion resistance ≥120mg/1000 cycles, suitable for indoor dry environments; Harsh Conditions: Imported PUR polyurethane sheath, oil-resistant (no corrosion after 72h diesel immersion), waterproof (IP67), UV aging resistant, suitable for outdoor/oily/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.
3. Key Performance Parameters Overview Base Value Custom Upgrade Rated Voltage Power Core 600/1000V, Control Core 250V AC Customizable Higher Voltage Level Bending Radius Mobile Installation 7.5×D, Fixed Installation 5×D (D = Outer Diameter) Minimum Possible Up to 5×D (Special Process) Ambient Temperature -40°C~90°C -60°C Low Temperature / -120°C High Temperature Custom Shielding Efficiency Power Type ≥ 60dB. Bending Frequency ≤5 times/second.
▍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.
