Quality Control
RZ1-K(AS) XLPE LSZH Flexible Cable
Raw Material Test
For the RZ1-K(AS) XLPE LSZH Flexible Cable, raw material testing starts with fine copper certification for flexibility and conductivity. XLPE granules are evaluated for contamination, thermal stability, and crosslinking efficiency via microscopy and TGA. Enhanced LSZH compound faces advanced halogen-free verification, higher flame-retardant loading checks, smoke opacity, and corrosivity tests per EN standards. The structured process: receipt inspection, random sampling, physical/mechanical testing (tensile, elongation), chemical analysis with ion chromatography, accelerated aging and fire simulation trials, and release decision. This ensures premium inputs, establishing the base for the RZ1-K(AS) XLPE LSZH Flexible Cable's superior flexibility, enhanced fire performance, and low-emission characteristics.
Process inspection
Process inspection in RZ1-K(AS) XLPE LSZH Flexible Cable production involves real-time quality assurance. Copper bunching monitors strand count and flexibility parameters. XLPE insulation extrusion ensures even bonding with capacitance gauges. Special LSZH sheath application includes online spark testing, thickness uniformity, and enhanced additive distribution control. Multi-core twisting verifies the lay ratio and filler. Printing durability is assessed. Critical steps: pre-extrusion dryness verification, parameter stabilization, real-time eccentricity monitoring, gel fraction and flexibility sampling, fire-retardant property intermediate checks, and defect removal protocols. This multi-stage control maintains the RZ1-K(AS) XLPE LSZH Flexible Cable's precise construction, excellent bend performance, and compliance with fire safety standards.
Finished Product
Completed RZ1-K(AS) XLPE LSZH Flexible Cable reels are subjected to comprehensive factory tests. Mandatory routines: DC resistance, high-potential AC test, insulation thickness, and sheath integrity. Advanced fire tests include bundled flame propagation, heat release, smoke production, and acidity measurement for CPR compliance. Flexibility tests cover torsion and repeated bending. Mechanical evaluations include cold bend and impact. The sequential process: sample conditioning, parameter application (voltage/heat), timed fire exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional verifications ensure chemical resistance and marking permanence. Passing all confirms the RZ1-K(AS) XLPE LSZH Flexible Cable's enhanced fire safety, flexibility, and reliability for critical installations.
Application
Perfect for emergency lighting, fire alarm systems, smoke extraction, and power supply in high-occupancy venues like theaters, metro stations, hotels, and commercial complexes requiring strict CPR classification and superior fire behavior.
