Powerchain PUR Cable

What is Powerchain PUR Cable?

The Powerchain PUR cable is a low-voltage, unshielded flexible control cable featuring Class 6 fine-stranded bare copper conductors, TPE/PP insulation, and an oil-resistant PUR outer sheath complying with VDE 0482-332-1-2, EN 60811-404, and IEC/EN 60332-1 standards. It is designed for fixed and continuous mobile power and control transmission up to 300/500V in heavy-duty drag chains and dynamic machinery without tensile load.

Engineered to withstand millions of continuous bending and travel cycles inside modern automated machinery, this cable resolves premature core failure and jacket cracking common in standard static cables. By combining an ultra-fine copper bunching geometry with a tough, halogen-free polyurethane jacket, Powerchain PUR delivers long flex life, low dielectric losses, and robust tear resistance across aggressive industrial manufacturing environments.

Powerchain PUR Cable Construction

• Conductor: Class 6 fine-stranded bare copper conductors per IEC/EN 60228 offering high dynamic flex life.
• Insulation: Thermoplastic Elastomer / Polypropylene (TPE/PP) compound offering low capacitance and smooth core movement.
• Bedding / Inner Layer: Compact core assembly optimized for continuous track articulation.
• Screen / Armour: Unscreened / Non-armored design engineered for minimum outer diameter and lightweight drag chain integration.
• Outer Sheath: Halogen-free, flame-retardant, oil- and abrasion-resistant Polyurethane (PUR) compound.
• Core Identification: Black cores with continuous white numbering + Green/Yellow protective earth conductor.
• Sheath Colour: Grey.

Applications

Powerchain PUR cables are engineered for continuously moving equipment, automation links, and dynamic drag chain tracks across harsh indoor and outdoor environments where lightweight, highly flexible unshielded wiring is required. Their halogen-free PUR formulation offers chemical endurance and notch resistance in aggressive production cells.

Typical installation environments include:

• Automated Drag Chains & C-Tracks: Continuous high-speed linear travel on CNC machining centers, automated gantries, and packaging lines.
• Industrial Robotics & Articulating Joints: Dynamic multi-axis pick-and-place systems and robotic transfer lines.
• Machining & Chemical Workshops: Manufacturing areas exposed to cutting oils, industrial coolants, hydraulic greases, and atmospheric humidity.
• Sub-Zero & Exterior Handling Equipment: Outdoor port cranes, cold-storage material handling conveyors, and weather-exposed industrial tracks down to -50°C.

Specifications & Dimensions

The Powerchain PUR cable series covers multi-core configurations from 2 cores up to 25 cores, with nominal conductor cross-sections spanning 0.5mm² to 16mm². Operating at a rated voltage of 300/500V, the cable supports fixed installations from -50°C to +80°C and continuous mobile flexing from -40°C to +80°C, maintaining a tight minimum bending radius of 4× OD (fixed) and 7.5× OD (flexed). All conductor strand counts, overall cable diameters, and nominal weights strictly align with EN 60811-404 and VDE manufacturing guidelines.

Frequently Asked Questions

Q: What is the primary difference between Powerchain PUR and Powerchain CP cables?
A: Powerchain PUR is an unscreened dynamic cable designed for minimal weight and compact dimensions in standard drag chains, whereas Powerchain CP incorporates an inner PUR sheath and a Tinned Copper Wire Braid (TCWB) screen to provide 360-degree EMC protection.

Q: Why is PUR outer sheathing superior to PVC for continuous dynamic applications?
A: Polyurethane (PUR) provides high tensile strength, superior tear/notch resistance, and extreme abrasion protection against drag chain walls, while maintaining mechanical flexibility down to -40°C and resisting degradation from aggressive industrial cutting oils and coolants.

Q: What are the minimum bending radius limits for Powerchain PUR cable?
A: The cable requires a minimum bending radius of 4 times the overall diameter (4× OD) for fixed installations and 7.5 times the overall diameter (7.5× OD) during continuous mobile flexing inside dynamic drag chains.

Q: What are Huadong Cable’s standard delivery times for international export orders?
A: Our standard production and export lead time is typically 15-25 working days, depending on the required core configuration, conductor cross-section, and total batch length.
