NORMAL STRUCTURE OF TRAILING CABLE
ComponentDescription
1. Conductor

Ultra-fine stranded bare copper or tinned copper wire: Key to high flexibility.

Made of many very fine copper strands, usually Class 5 (flexible conductor) or Class 6 (super flexible conductor) to withstand frequent bending, twisting, and stretching without breaking.

2. Insulation

Elastomer materials commonly used:

 • EPR (Ethylene Propylene Rubber): Excellent heat resistance, ozone resistance, weather resistance, and electrical insulation.

• HEPR (Hard Ethylene Propylene Rubber): Enhanced mechanical strength based on EPR.

• EVA (Ethylene Vinyl Acetate): Good elasticity and low temperature resistance.

• XLPE (Cross-linked Polyethylene): Used in medium and high voltage cables, provides excellent electrical performance and heat resistance.

3. FillingTextile or rubber fillers: In multi-core cables, non-absorbent fillers or extrusion rubber are used between insulated cores to maintain cable roundness and provide cushioning and support.
4. ShieldingConductive layer / Shielding: For medium/high voltage cables, semiconductive layers (shields) are placed between conductor and insulation, and outside insulation, to equalize electric field, reduce partial discharge, and improve electrical performance and cable life. Some cables shield individual cores to reduce electromagnetic interference.
5. Earth Conductor and/or Pilot Core

Earth wire: Essential, usually placed alongside the main power cores for safety grounding.

Pilot core/control core: Many heavy-duty or high-voltage trailing cables include one or more smaller pilot cores used for grounding continuity monitoring systems or remote control signals. 

If grounding continuity is lost, the pilot core triggers protection devices to cut power, greatly enhancing safety.

6. Outer Sheath

High-strength elastomer materials: Key to withstand harsh environments.Common materials:

• CPE (Chlorinated Polyethylene)• PCP (Polychloroprene, commonly called Neoprene)

• PUR (Polyurethane): Excellent abrasion, cut, oil, chemical, and tear resistance.

• TPU (Thermoplastic Polyurethane): Similar to PUR but easier to process.

The outer sheath is usually thick and tough, resistant to wear, compression, impact, oil, chemicals, UV, and harsh weather.

7. Reinforcement (Optional)Tensile elements: For applications requiring high tensile strength, textile fibers (e.g., Kevlar) or steel wire ropes may be integrated in the cable core or beneath the sheath to distribute stress and protect conductors.Internal braiding reinforcement: Some cables have internal braid layers to improve resistance to twisting and stretching.

Industrial-Grade Flexible Trailing & Reeling Cable: Technical Overview
This high-performance cable is engineered for dynamic mechanical stress in demanding industrial environments. Designed for continuous motion, it provides superior reliability for power transmission and control signals in applications requiring frequent bending, twisting, and dragging.
Key Performance Engineering
  • Superior Flexibility: Utilizing Class 5 or Class 6 ultra-fine stranded copper, the conductor core is optimized to withstand millions of flex cycles without fatigue or breakage.
  • High-Endurance Insulation: Available in EPR, HEPR, and XLPE, offering exceptional thermal stability (up to 90°C) and resistance to ozone and moisture.
  • Ruggedized Outer Sheath: Encased in specialized elastomers like PUR (Polyurethane) or CPE (Chlorinated Polyethylene), providing a "heavy-armor" defense against abrasion, tearing, oils, chemicals, and UV exposure.
  • Integrated Safety & Monitoring: High-voltage variants feature Pilot Cores and Earth Conductors to support grounding continuity monitoring, ensuring immediate power-cut protection in case of cable damage.
Voltage-Specific Applications
  • Low Voltage (300V – 1kV): Precision-engineered for Automated Guided Vehicles (AGVs), Hoists, Cranes, and Robotic Systems.
  • Medium/High Voltage (1.9kV – 11kV): Designed for extreme-load environments including Mining Excavators, Electric Shovels, and Heavy Port Machinery.
Mechanical Reinforcement
For high-tension vertical or long-distance reeling, these cables can be integrated with Kevlar (Aramid) fibers or steel wire braiding to prevent conductor elongation and ensure structural integrity under heavy tensile loads.
