BASKET SPREADER 740 (YSLTOE) is engineered specifically for hoisting and control applications where mechanical flexibility and electrical reliability must coexist in marine environments. Unlike load-bearing structural cables (which prioritize tensile strength), control cables emphasize: Conductor flexibility – Repeated bending over pulleys without mechanical fatigue Insulation integrity – Voltage breakdown resistance under salt-fog corrosion Mechanical damping – Rope-like flexibility to drape naturally in spreader bar frames Environmental barrier – Outer sheath blocks salt, moisture, and UV penetration Core Design Elements: Component Material Specification Function Port Environment Benefit Conductor Flexible red copper Class 6 (IEC 60228) Carries 300/500V power; enables bending flexibility High purity copper resists galvanic corrosion Insulation PVC type YI2 (IEC 60811) Electrical isolation; voltage breakdown resistance (2 kV test) PVC with marine additives prevents salt-induced tracking Central Unit Aramide yarns (Kevlar™ equivalent) Mechanical load-bearing backup; structural integrity Aramide resists moisture & salt; absorbs vibration stress Outer Sheath PUR type 11YM1 (DIN 73377) Environmental barrier; UV/ozone/moisture protection Superior salt-fog resistance; 20+ year marine lifespan
