Products Description
JZ-HF is a European-standard high-flex control cable specially engineered for continuous reciprocating installation inside energy drag chains, designed strictly referencing DIN VDE 0285-525-2-51 & DIN EN 50525-2-51 industrial specification for dynamic machine wiring applications.
Internal Structural Working Principle
The cable adopts a five-layer composite structural design optimized for repeated flex fatigue resistance:
Conductor Layer: Extra-fine bare copper wires stranding in Class6 standard, smaller single copper filament reduces internal shear stress during frequent bending to avoid conductor fracture after long-term movement;
Core Insulation Layer: Z7225 special modified PVC insulation with stable insulation resistance ≥20MΩ·km at ambient temperature, uniform extrusion controlled by online laser thickness inspection to keep eccentricity ≤10% as production QC standard;
Layered Core Stranding: Multi-cores stranded with scientifically calculated optimized lay length, each stranding layer wrapped with non-woven fleece to restrict core displacement during drag chain back-and-forth motion, preventing core friction abrasion inside the cable;
Optional Ground Core: For variants over 3 cores, GN-YE green-yellow protective earth core is fixed on outer core layer per DIN standard; OZ-HF model excludes ground conductor for cost-saving customized demand;
Outer Sheath Layer: DIN-certified TM5 special oil-proof PVC compound extruded as outer jacket (RAL7001 grey), formulated to resist machine mineral oil dilution per DIN EN 60811-404 liquid immersion test regulation.
All raw materials are sourced from certified EU-grade compound suppliers; finished cables go through full batch lab verification before warehouse release, avoiding performance deviation caused by unstable raw material quality. Unlike ordinary Class5 flexible control cables (YSLY series), JZ-HF's structural optimization targets continuous dynamic load instead of static fixed laying, making it the mature option for long-running drag chain wiring in automation equipment.

Features
① Dynamic Flex Durability
Accelerated drag chain fatigue test in our in-house lab proves ≥1,000,000 continuous reciprocating bending cycles under standard 7.5×OD bend radius, no core breakage or sheath cracking, matching mainstream European brand JZ-HF performance benchmark; optimized layered fleece wrapping eliminates inner core shift during high-speed drag movement.
② Oil & Chemical Resistance
Outer sheath compound passes DIN EN 60811-404 mineral oil immersion test, no swelling, hardening or cracking after 24h immersion in common industrial machine oil, suitable for lubricant-rich machining workshop environment.
③ Stable Electrical Performance
Class6 ultra-fine copper conductor keeps stable DC resistance within DIN tolerance range after long-term repeated bending; Z7225 insulation maintains consistent insulation resistance under full working temperature span, reducing signal/control circuit failure risk.
④ Wiring Convenience
DIN-standard sequential white digital marking on black cores enables fast field identification without extra core labeling; meter marking printed continuously on outer sheath for accurate on-site cutting and inventory management.
⑤ Environment & Safety Compliance
Zero cadmium, zero silicone in all compound formulations; outer sheath meets IEC60332-1-2 vertical flame retardant requirement, self-extinguishes after flame source removal without flame spreading.
