Crd Trailing Cables

CRD trailing cables (Cable Reeling Drum cables) are specialized, heavy-duty electrical cables designed for moving industrial machinery that requires a constant power or control signal while in motion. Key Features and ConstructionThese cables are built for durability in harsh environments, featuring flexible materials that prevent internal damage during repeated movement. High Flexibility: Uses Class-5 flexible tinned or bare copper conductors to handle frequent bending and twisting. Durable Insulation: Typically insulated with EPR (Ethylene Propylene Rubber), which provides high dielectric strength and resistance to extreme temperatures ranging from -20°C to +90°C. Robust Sheathing: Encased in HOFR (Heat, Oil, and Flame Retardant) elastomer or neoprene jackets to protect against abrasion, chemicals, and UV exposure. Anti-Kink Braid: Many designs include a textile or fabric braid embedded between the inner and outer sheaths to prevent torsion and kinking. Voltage Grade: Generally rated for 600/1100 V-AC. Bending Radius: Often specified as 10D (10 times the overall diameter) for flexible applications. Core Configurations: Available in multicore options (2 to 30+ cores) to support both power and control signal transmission. Standards: Commonly manufactured to comply with IS: 9968, IEC-60228, and IEC-60502 standards.
