Deep sea mining represents one of humanity's most ambitious technological frontiers, targeting mineral resources at ocean depths that would have been unimaginable just decades ago. The International Seabed Authority (ISA) has granted 31 exploration licenses as of 2024, including 19 for polymetallic nodules primarily in the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean, where deposits lie at depths of 4,000 to 6,000 meters below the surface [1][2]. These nodules contain economically critical metals including copper, nickel, cobalt, and manganese, with the CCZ alone estimated to hold over 21 billion metric tons of nodules. 深海采矿系统由生产支持船、深海集矿机器人、提升管道系统和最关键的脐带电缆组成。Deep sea mining systems consist of production support vessels (PSVs), subsea collector vehicles, riser and lift systems (RALS), and most critically, umbilical power cables that must transmit electrical power, control signals, and data communications across vertical distances exceeding 5,000 meters. The Chinese submersible Striver reached the Mariana Trench at 10,909 meters depth in 2020, demonstrating that engineering solutions for ultra-deep operations are technologically feasible, though commercially scaled mining operations remain in the exploratory phase [3][4].

Potash and salt mining operations present one of the most chemically aggressive environments for electrical infrastructure. Unlike conventional mining operations where mechanical wear dominates cable failure modes, potash mines create a uniquely hostile chemical environment that systematically attacks standard cable materials through multiple corrosion pathways. Understanding why cables fail in these conditions requires examining the specific chemistry of the mining environment and how it interacts with different cable sheath materials. 钾盐矿是世界上最重要的化肥生产基地，但同时也是电缆系统面临最严峻腐蚀环境的场所之一。Potash mines are among the world's most important fertilizer production sites, but they also present one of the most severe corrosive environments for cable systems. The high chloride content, combined with moisture, hydrogen sulfide, and elevated temperatures, creates conditions that rapidly degrade standard rubber cable sheaths

In demanding industrial applications such as mining operations, crane systems, and material handling equipment, the selection of appropriate cable sheath materials directly influences operational reliability and safety. The sheath represents the cable's first line of defense against mechanical stress, environmental degradation, and electrical hazards. This technical analysis examines how Ethylene Vinyl Acetate (EVA) sheath compounds improve the performance characteristics of NTSCGEWÖU-type trailing and reeling cables compared to standard Chlorinated Polyethylene (CPE) constructions, particularly regarding voltage withstand capabilities and vertical installation requirements.
