1. Materials and Structural Parameters
Product Structure ● Product Model: DRAG300 ● Product Specifications: (2-38) cores, (0.14-1.5) mm²; (2-25) cores, (2.0-16) mm² ● Conductor: High bending strength fine bare copper multi-strand strands (compliant with IEC60228 CL6 VDE0295 CL6 standards) ● Insulation: High mechanical performance PVC blend (compliant with VDE0207 standards) ● Core Twisting Method: Number of cores < 12 cores, Core wire is twisted together in short pitch layers. Core core ≥ 12 cores, with two double twists, especially the torsion-resistant structure, with a reinforced core in the middle ● Core identification: cross-sectional area <0.5mm². Core wire is distinguished by color (red, yellow, green, blue, black, gray, white, purple, pink, brown, orange), etc. Cross-sectional area ≥ 0.5mm², one yellow-green wire core, the rest black with white numbers ● Shielding: high bending strength tin-plated braided shielding, wire coverage 80% ● Outer sheath: low-viscosity PVC base compound, Suitable for drag chains ● Sheath color: Black (similar to RAL9005) (other colors according to customer requirements) Gray (similar to RAL7001) Orange (similar to RAL2003) Technical Features ● Rated voltage: <0.5mm² 300/300V; ≥ 0.5mm² 300/500V ● Test voltage: <0.5mm² 1500V/5min; ≥0.5mm² 22000V/5min ● Operating temperature range: -30°C to 80°C (mobile installation) When travel < 10 meters, bending radius is: 6.8×D; when travel ≥ 10 meters, bending radius is: 7.5×D ● Operating temperature range: -40°C to 90°C (fixed installation) Bending radius: 5×D ● Maximum speed: 10 m/s; 5 meters/second (overhead/sliding) ● Maximum speed: 80 meters/second ● Maximum temperature during short circuit: 250°C ● Bending life: 40 times/minute, > 4 million times ● Flame retardant properties: Complies with IEC332-1 standard ● Material properties: shallow water resistance, oil resistance, radiation resistance, cold resistance, wear resistance, can withstand heavy mechanical forces ● Faster acceleration and stronger flexural resistance than medium trailer chain cables Application scenarios ● Used for high loads ● Especially suitable for horizontal overhead and long travel scenarios requiring shielding for travel less than 100 meters ● Suitable for logistics equipment systems, hardware stamping, machinery (labor), construction machinery, docks, fire trucks, automobile manufacturing, wood and stone processing equipment, machine tool processing, etc
