semiconductive tape

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

(N)3GHSSHCH Flexible Power Cable: HFFR средневольтный кабель для mobile operating equipment, mines и hazardous underground environments

(N)3GHSSHCH — это гибкий средневольтный силовой кабель для подключения mobile operating equipments в шахтах и подземных выработках с hazardous environments. По предоставленным данным он также применяется в stationary operation, например для high-voltage transformers in mining and tunnelling. Главное отличие конструкции — использование special halogen free and flame retardant HFFR compound для внутренних и наружной оболочек, в сочетании с EPR-изоляцией 3GI3, pilot control cores, 3E protective conductors, ÜL monitoring conductor и galvanized steel wire braiding с покрытием минимум 75%.
Type SHD-GC cables represent a specialized category of shielded medium voltage mining cables designed for the most demanding industrial applications. These cables are specifically engineered for use in mining operations where they must withstand extensive abrasion, impact, vibration, tension, and cut-through conditions that commonly cause standard cable failures. The designation "SHD-GC" indicates Super Heavy Duty with Ground Check capability, making them essential for applications such as continuous mining machines, longwall systems, blast hole drillers, shovels, draglines, and other mobile mining equipment.
