Prysmian PROTOLON (SM) 3x150+3x25/3 6/10kV is a specialized high-voltage reeling cable engineered for environments where mechanical stress, torsional loading, and cable flexibility are as critical as electrical performance. Unlike standard medium-voltage power cables, PROTOLON cables are designed for continuous reeling and unreeling—the cable must bend, twist, and flex thousands of times over their service life without insulation cracking, conductor breakage, or protective conductor separation.

Rail-mounted gantry (RMG) cranes are the largest and most powerful material handling systems in modern container ports and intermodal yards. Unlike traditional spreader cranes that hang from a fixed trolley, RMG cranes are completely self-contained electromechanical systems mounted on wheels that roll along parallel steel rails, spanning the entire width of a container yard. The electrical architecture of an RMG is fundamentally different from other port equipment, and this difference cascades into specific requirements for power transmission cables. RMG是现代集装箱港口最大最强的物料搬运系统。其完全自推进的电气架构对电缆提出了特殊要求。
