What is Powerchain CY Cable?
The Powerchain CY cable is a low-voltage, highly flexible shielded data and control cable featuring Class 6 fine-stranded bare copper conductors, PVC insulation, an inner PVC bedding sheath, a tinned copper wire braid (TCWB) screen, and an oil-resistant PVC outer sheath complying with VDE 0482-332-1-2 and IEC/EN 60332-1 standards. It is designed for fixed and continuous mobile power and signal distribution up to 300/500V in standard drag chains and automated machinery without tensile load.
Engineered to prevent signal distortion and conductor fatigue in continuously moving equipment, the cable incorporates an ultra-fine multi-strand conductor geometry paired with a dense TCWB shielding matrix. This layered construction provides 360-degree electromagnetic compatibility (EMC) against variable frequency drive (VFD) noise while offering superior chemical resistance to cutting oils, industrial coolants, and environmental moisture in modern manufacturing cells.
Powerchain CY Cable Construction
- Conductor: Class 6 fine-stranded bare copper conductors delivering high flex endurance under dynamic motion.
- Insulation: Polyvinyl Chloride (PVC) compound engineered for low dielectric loss and continuous flexibility.
- Inner Sheath: Extruded Polyvinyl Chloride (PVC) bedding serving as a mechanical buffer and core stabilizer.
- Screen: Tinned Copper Wire Braid (TCWB) providing comprehensive EMC protection against electromagnetic interference.
- Outer Sheath: Industrial-grade, chemical- and oil-resistant Polyvinyl Chloride (PVC), flame retardant per IEC/EN 60332-1.
- Core Identification: Black cores with continuous white numbering + Green/Yellow protective earth core.
- Sheath Colour: Grey.
Applications
Powerchain CY cables are engineered for dynamic drag chains, festoon setups, and continuous mobile data control installations across automated industrial environments. Their TCWB screen and robust PVC formulation protect signal paths from electromagnetic disturbances and chemical degradation.
Typical installation environments include:
- Automated Drag Chains & Cable Tracks: Continuous guiding and flex cycling on CNC machine tools, automated gantries, and packaging lines.
- Robotics & Material Handling: Multi-axis pick-and-place equipment, assembly conveyors, and automated storage systems.
- Industrial Control Panels & Switchgears: EMC-sensitive interconnect lines between variable speed drives, PLCs, and servo motors.
- Chemical & Machining Workshops: Factory floors exposed to industrial chemical runoff, lubricating oils, and atmospheric humidity.
Specifications & Dimensions
The Powerchain CY cable series is available in versatile multi-core configurations ranging from 2 cores up to 25 cores, with nominal conductor cross-sections spanning 0.5mm² to 6mm². Operating at a rated voltage of 300/500V, the cable supports fixed installations from -40°C to +70°C and continuous mobile flexing from -5°C to +70°C, maintaining a minimum bending radius of 4× OD (fixed) and 10× OD (flexed). All conductor strand densities, overall cable diameters, and nominal weights strictly conform to VDE and EN manufacturing guidelines.

Frequently Asked Questions
Q: What is the functional difference between Powerchain CY and Powerchain CP cables?
A: Powerchain CY utilizes PVC insulation and inner/outer PVC sheaths for standard drag chains in indoor factory environments, whereas Powerchain CP uses TPE/PP insulation with a PUR outer sheath for severe outdoor abrasion and extreme low-temperature flexibility down to -50°C.
Q: Why is an inner PVC sheath applied beneath the TCWB braid on Powerchain CY?
A: The extruded inner PVC sheath provides a smooth, uniform cylindrical bed that stabilizes the laid-up cores and prevents the tinned copper braid wires from abrading or cutting into the primary conductor insulation during repeated bending cycles.
Q: What is the permissible bending radius for Powerchain CY in moving drag chains?
A: In dynamic drag chain applications, the cable requires a minimum bending radius of 10 times the overall cable diameter (10× OD) to prevent mechanical fatigue and conductor breakage.
Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We provide flexible commercial terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for overseas engineering and OEM projects.
