O que é PROTOLON (M) R-(N)TSCGEWOEU Arctic -50C 6/10KV: Análise Técnica do Cabo de Média Tensão para Enrolamento Flexível até -50°C

O PROTOLON (M) R-(N)TSCGEWOEU Arctic -50C 6/10KV é um cabo flexível de média tensão para enrolamento, desenvolvido para grandes máquinas móveis de manuseio de material em minas a céu aberto, como escavadeiras elétricas, dumpers e britadores móveis. Sua característica decisiva é a capacidade de operar de forma totalmente flexível até -50°C, mantendo a arquitetura de cabo de carretel para altas solicitações mecânicas: condutores de cobre classe FS, sistema isolante EPR PROTOLON, camadas semicondutoras, condutor de proteção dividido em três interstícios, reforço de poliéster e capa externa PCP resistente a abrasão, óleo, ozônio, radiação UV e água do mar.

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%.
