Control Cable
Product Overview
Industrial control cables transmit low-voltage signals and instrumentation data between automation equipment, sensors, and centralized control units. Engineered for fixed or continuous-flex installations, these multi-conductor harnesses maintain signal integrity in environments exposed to electromagnetic interference (EMI), mechanical stress, cutting fluids, and extreme temperatures. Conductor counts range from 2 to 60 cores, available in unshielded configurations for standard signal routing or overall/individually shielded designs for noise-sensitive industrial circuits.

Key Features
Conductor Spec:
Annealed bare or tinned electrolytic copper strands meeting ASTM B3 or IEC 60228 Class 5/6 standards for optimal conductivity and mechanical flexibility.
Shielding Efficiency:
Tri-laminate aluminum-mylar foil paired with tinned copper wire braid delivering >= 85% optical coverage to suppress high-frequency EMI.
Jacket Compounds:
Extruded PVC, PUR, or halogen-free LSZH outer sheaths rated for oil resistance, UV exposure, and mechanical abrasion.
Bending Radius:
Static installation radius down to 4 x outer diameter (OD); continuous flexing chain applications rated down to 7.5 x OD over 5 million flexing cycles.
Product Construction
Conductors:
Fine-stranded electrolytic copper (Class 5/6 flexible strands).
Insulation:
Color-coded or numbered PVC, XLPE, or TPE core insulation with high dielectric strength.
Cabling:
Cores stranded in concentric layers or optimal pitches to minimize mechanical stress during bending.
Separator/Bedding:
Non-hygroscopic wrapping tape or inner extruded filler to maintain circular cable geometry.
Shield:
Aluminum-mylar tape with a drain wire plus tinned copper braid armor.
Outer Jacket:
Flame-retardant, chemical-resistant thermoplastic or elastomer compound (black or grey standard, custom colors available).
Applications
Machine Tools & CNC:
Interconnecting PLC controllers with servo drives, limit switches, and feedback encoders.
Material Handling:
Crane controls, stacker cranes, and high-speed conveyor sorting systems.
Automotive Production Lines:
Multi-axis welding robots and automated guided vehicles (AGVs) requiring continuous torsion and bending endurance.
Process Industries:
Wastewater treatment plants and chemical processing units requiring moisture- and chemical-resistant cabling.
Shielding Types:
Unshielded (YY), overall shielded (CY), and paired/individually shielded with overall shield variants.
Conductor Sizes:
24 AWG to 10 AWG (0.22 mm^2 to 6.0 mm^2).
Core Identification:
Black cores with white numerical markers plus green/yellow ground wire; alternative international color codes (DIN 47100, IEC) available upon request.
Armor Options:
Galvanized steel wire braid (GSWB) or corrugated steel tape for crush and rodent protection in heavy industrial runs.
Manufacturing & Quality Control
Drawing & Annealing:
In-house copper rod breaking and continuous annealing lines control elongation rates within +/- 1% to ensure uniform flexibility.
Extrusion Process:
Precision cross-head extruders apply insulation and jacket compounds with laser-monitored eccentricity gauges, maintaining wall thickness variance under +/- 0.05 mm.
Testing Protocol:
Spark testing at 3kV to 6kV during extrusion to detect pinholes.
01
Conductor DC resistance testing via automated bridge meters.
02
Tensile strength and elongation testing of jacket materials per IEC 60811.
03
Certifications: RoHS and REACH compliant, ISO 9001:2015 certified manufacturing facility.
04
Customization
Jacket Formulation:
Tailored compounds for specific chemical exposure (e.g., biodiesel, cutting oils, hydraulic fluids) or extreme low-temperature flexibility down to -50 degree C.
Outer Print:
Custom laser-etched legends including part numbers, sequential meter markings, and client logos.
Packaging:
Cut-to-length wooden reels, returnable steel drums, or coiled bundles packaged in reinforced export-grade cartons.
How to Choose
Determine Electrical Load:
Verify operating voltage and current draw. Select conductor cross-section (e.g., 1.0 mm^2 for signal circuits, 2.5 mm^2 for low-draw actuator power).
Evaluate Environmental Exposure:
Identify presence of oils, UV radiation, moisture, or extreme ambient temperatures to select correct jacket material (PUR for high abrasion/oil; PVC for standard indoor runs).
Assess Mechanical Stress:
Specify static routing or dynamic cable track (C-track) applications. Dynamic routing requires fine-stranded copper (Class 6) and TPE/PUR insulation to prevent core breakage.
Check Interference Levels:
Select braided copper shielding if cables run parallel to high-voltage power lines or variable frequency drives (VFDs).
