Halogen-free Reeling Cable

Updated: 2026-08-03

Overview

Halogen-free reel cables are engineered for applications requiring frequent winding and unwinding, such as in cranes, automated guided vehicles (AGVs), and stage equipment. Unlike traditional PVC cables, they eliminate halogens like chlorine and bromine, which emit corrosive gases when burned. This makes them safer for enclosed spaces and environmentally compliant. These cables often incorporate LSZH (Low Smoke Zero Halogen) sheathing to minimize smoke toxicity during fires. Their construction includes finely stranded conductors and reinforced jackets to withstand mechanical stress, ensuring longevity in dynamic installations.

Structure and Working Principle

A typical halogen-free reel cable consists of multiple finely stranded copper conductors for flexibility, insulated with cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR). The outer sheath is made of LSZH compounds, providing flame resistance and low smoke emission. The cable’s design ensures minimal torque during spooling, preventing twisting or damage. Some variants include spiral shielding or aramid yarn reinforcement for tensile strength. The absence of halogens allows safer operation in confined areas, as it avoids releasing toxic hydrogen chloride gas during combustion.

Key Features

Flame retardancy is a core feature, meeting standards like IEC 60332 for fire resistance. The LSZH material reduces smoke density by over 90% compared to PVC, critical for visibility during emergencies. Flexibility is achieved through high-strand conductors (e.g., Class 5 or 6 per IEC 60228), enabling up to 5 million bending cycles. Additional features may include oil resistance (tested per EN 60811) and UV stability for outdoor use. Abrasion-resistant jackets, often polyurethane (PUR), extend service life in rugged environments.

Application Areas

These cables are widely deployed in heavy industries, including port cranes, mining equipment, and renewable energy systems like wind turbines. Their flexibility suits robotic arms and automated production lines where constant movement is required. In entertainment, they power moving stage lights and rigging systems. The halogen-free property is mandatory in public infrastructure (e.g., subways) due to strict fire safety regulations. Marine and offshore applications also favor them for corrosion resistance.

Maintenance and Precautions

Regularly inspect cables for jacket wear, especially at entry points to reels or guides. Replace if cracks or exposed conductors are detected. Avoid sharp bends beyond the specified minimum radius (typically 5–8× cable diameter). Clean reels periodically to remove debris that could abrade the cable. Store unused cables in dry conditions to prevent moisture absorption, which may degrade insulation. Follow manufacturer guidelines for reel acceleration/deceleration rates to prevent "cable throw."

B2B Procurement Guide

Specify conductor size (e.g., 4–50 mm²) and voltage rating (commonly 300/500V or 0.6/1kV). Confirm certifications like CE, RoHS, or UL for target markets. Shielding (foil vs. braid) should match EMI requirements. Request samples to test flexibility and bend resistance. Bulk buyers should negotiate MOQs (Minimum Order Quantities) and lead times, as custom lengths/colors may require 4–6 weeks. Partner with suppliers offering technical support for reel system compatibility checks.
