PUR-JZ Cable

What is Control PUR-JZ Screened Cable?

The Control PUR-JZ Screened cable is a low-voltage, unarmored and shielded flexible control cable featuring Class 5 flexible stranded bare copper conductors, PVC insulation, a tinned copper wire braid (TCWB) screen, and an abrasion-resistant PUR outer sheath complying with IEC/EN 60811-404 and IEC/EN 60332-1 standards. It is designed for fixed wiring and moved power or signal transmission up to 300/500V in heavy industrial engineering, machine tools, and steel production plants under medium mechanical stress.

Engineered to resist aggressive mechanical wear and harsh chemical exposure on factory floors, the cable combines an overall TCWB shield that prevents electromagnetic interference (EMI) with a tough polyurethane outer jacket. This high-grade PUR formulation provides exceptional resistance against cutting oils, industrial coolants, hydraulic greases, and mechanical abrasion, preventing outer jacket failure and ensuring long-term signal clarity across demanding production environments.

Control PUR-JZ Screened Cable Construction

• Conductor: Class 5 flexible stranded bare copper conductors per IEC/EN 60228 delivering superior flexibility and low electrical resistance.
• Insulation: Polyvinyl Chloride (PVC) compound engineered for dependable dielectric strength up to +80°C.
• Bedding / Inner Layer: Compact multi-core assembly designed for smooth core movement and flexible routing.
• Screen: Tinned Copper Wire Braid (TCWB) providing a high-coverage 360-degree electromagnetic compatibility (EMC) shield.
• Outer Sheath: Specially formulated wear-, tear-, oil-, and coolant-resistant Polyurethane (PUR) compound, flame retardant per IEC/EN 60332-1.
• Core Identification: Black cores with continuous white numbering + Green/Yellow protective earth conductor.
• Sheath Colour: Grey.

Applications

Control PUR-JZ Screened cables are specifically designed for interconnection in industrial machinery, assembly lines, and steel works where mechanical friction, chemical contamination, and electrical noise are present. Their durable PUR jacket ensures reliable operation in dry, damp, and wet environments under medium mechanical stress without tensile load or forced guidance.

Typical installation environments include:

• Machine Tool Building & Metalworking: Power and control wiring constantly exposed to cutting fluids, coolants, and lubricating greases.
• Steel Works & Heavy Industrial Engineering: Machinery links requiring extreme abrasion and tear resistance against rough surfaces.
• Automated Production Lines & Assembly Plants: Flexible control cabling near motor drives and electrical switchgear requiring EMC suppression.
• Industrial Processing Equipment: Free-moving flexible connections in manufacturing workshops operating up to +80°C.

Specifications & Dimensions

The Control PUR-JZ Screened cable portfolio covers multi-core configurations from 2 cores up to 25 cores, with nominal conductor cross-sections spanning 1.0mm², 1.5mm², 2.5mm², 4.0mm², and 6.0mm². Operating at a rated voltage of 300/500V, the cable supports fixed ambient temperatures from -40°C to +80°C and moved flexible installation from -5°C to +80°C, maintaining a tight minimum bending radius of 5× OD (fixed) and 10× OD (flexed). All conductor strand densities, overall cable diameters, and nominal weights strictly align with IEC/EN 60811-404 and European harmonized manufacturing standards.

Frequently Asked Questions

Q: What is the main advantage of a Polyurethane (PUR) outer sheath compared to PVC in industrial workshops?
A: Polyurethane (PUR) offers vastly superior mechanical abrasion, tear, and notch resistance, while preventing outer jacket swelling, hardening, or cracking when continuously exposed to industrial cutting oils and coolants.

Q: How does the TCWB screen protect automated machinery circuits?
A: The Tinned Copper Wire Braid (TCWB) forms a low-resistance 360-degree conductive envelope that intercepts external electromagnetic interference (EMI) and prevents high-frequency radiation from disrupting neighboring control circuits.

Q: What are the minimum bending radius requirements for Control PUR-JZ Screened cables?
A: The cable requires a minimum bending radius of 5 times the overall diameter (5× OD) for fixed installations and 10 times the overall diameter (10× OD) for flexible, moved applications without tensile load.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We provide standard international commercial payment terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering contractors and industrial machinery OEMs.
