RHEYFIRM® cable series, developed by Nexans, represents the industry benchmark for high-voltage reeling cables in demanding crane and material handling applications. Within this series, the distinction between splittable earth configurations (designated with "S" variants) and standard configurations using the (N)TSKCGEWÖU designation has significant technical and operational implications. This analysis examines whether generic splittable earth reeling cables can serve as direct replacements for Nexans' proprietary "S" series cables.

N3GHSSYCY — это экранированный высоковольтный гибкий кабель промышленного класса, специально разработанный для подключения мобильного оборудования в шахтах и подземных выработках со взрывоопасной средой. Кабель соответствует международному стандарту DIN VDE 0250, часть 605 и выпускается в двух номинальных напряжениях: 3.6/6 кВ и 6/10 кВ. Особенностью конструкции является наличие фазоконцентрического заземляющего проводника и общего концентрического экрана мониторинга, которые в сочетании со схемой высоковольтной защиты позволяют контролировать кабель на наличие дефектов изоляции и повреждений от внешних воздействий.

SUPROMONT (N)3GHSSYCY 6 kV – 30 kV

The evolution of underground mining operations toward increasingly mechanized production methods and deeper extraction depths has driven corresponding evolution in electrical infrastructure requirements, progressively expanding from early kilowatt-scale low voltage systems toward modern megawatt-scale installations requiring medium voltage power distribution. The fundamental electrical engineering principle underlying this evolution recognizes that power transmission capacity equals voltage multiplied by current, enabling equivalent power delivery at substantially reduced current levels through voltage increase from conventional low voltage levels of six hundred sixty to one thousand one hundred forty volts to medium voltage levels ranging from three point six kilovolts to thirty kilovolts. This current reduction delivers multiple operational advantages including proportional reduction in conductor cross-sectional area requirements decreasing cable weight and installation cost, reduced resistive losses improving energy efficiency and decreasing cooling requirements, and enhanced power quality through reduced voltage drop across transmission distances extending hundreds of meters or kilometers in modern mining operations.
