Introduction to PROTOMONT NSHXOEU Cables<\/h2>\n \n <p>The PROTOMONT NSHXOEU series represents an advanced category of low voltage flexible rubber cables specifically engineered for demanding mining and industrial environments. These cables feature a specialized EVA-based outer sheath compound (5GM3) combined with EPR (Ethylene Propylene Rubber) insulation, providing an optimal balance of flexibility, durability, and environmental resistance for medium mechanical stress applications.<\/p>\n\n <p>The designation NSHXOEU follows the German cable nomenclature system established by DIN VDE standards, where each letter indicates specific construction characteristics. The “X” in the designation indicates the halogen-reduced EVA sheath compound, while “H” denotes the heavy-duty rubber construction suitable for harsh environments. According to <a href=\"https:\/\/www.elandcables.com\/electrical-cable-and-accessories\/cables-by-standard\/vde0250-cable\" rel=\"nofollow noopener\" class=\"external-link\" target=\"_blank\">Eland Cables<\/a>, DIN VDE 0250 has achieved global recognition as the ultimate standard for tough rubber sheathed flexible cables, particularly for mining and material handling equipment.<\/p>\n\n <div class=\"highlight-box\">\n <p><strong>Key Specification Summary:<\/strong> PROTOMONT NSHXOEU cables operate at a rated voltage of <span class=\"data-highlight\">0.6\/1 kV (600\/1000V)<\/span>, with maximum permissible operating voltages of <span class=\"data-highlight\">0.7\/1.2 kV AC<\/span> and <span class=\"data-highlight\">0.9\/1.8 kV DC<\/span>. The cables feature EPR insulation (PROTOLON 3GI3) with a conductor temperature rating of <span class=\"data-highlight\">90\u00b0C<\/span> and short-circuit temperature capability of <span class=\"data-highlight\">250\u00b0C<\/span>. Maximum submersion depth is <span class=\"data-highlight\">500 meters<\/span>.<\/p>\n <\/div>\n\n <p>As documented by <a href=\"https:\/\/feichuncables.com\" rel=\"dofollow\" class=\"external-link\">Feichun Cables<\/a>, these specialized cables are manufactured to meet the highest industry standards including DIN VDE, IEC, and various international mining regulations, demonstrating their suitability for global underground and surface mining operations.<\/p>\n <\/section>\n\n <!-- Section 2: Purpose and Applications -->\n <section id=\"purpose\">\n <h2>2. Purpose and Applications<\/h2>\n \n <p>PROTOMONT NSHXOEU cables are engineered for flexible use and fixed installation across a diverse range of demanding industrial applications. Their construction enables reliable operation in environments where standard cables would experience accelerated degradation.<\/p>\n\n <h3>2.1 Primary Application Areas<\/h3>\n \n <p>The cables are specifically designed for underground mining applications, tunnel building operations, open-cast mining environments, quarries, construction sites, and similar applications with medium mechanical stresses. They can be utilized both indoors and outdoors, in explosion-hazard areas, across industrial facilities, and in agricultural operations.<\/p>\n\n <div class=\"feature-grid\">\n <div class=\"feature-card\">\n <h5>Underground Mining<\/h5>\n <p>Power supply for continuous miners, shuttle cars, loading equipment, and ventilation systems in confined underground environments requiring flame-retardant cables.<\/p>\n <\/div>\n <div class=\"feature-card\">\n <h5>Tunnel Construction<\/h5>\n <p>Flexible power distribution for tunnel boring machines, conveyor systems, and support equipment in demanding tunnel building applications.<\/p>\n <\/div>\n <div class=\"feature-card\">\n <h5>Open-Cast Mining<\/h5>\n <p>Mobile equipment connections for excavators, draglines, stackers, and reclaimers in surface mining operations with outdoor exposure.<\/p>\n <\/div>\n <div class=\"feature-card\">\n <h5>Quarry Operations<\/h5>\n <p>Power cables for crushing equipment, conveyors, and processing machinery in stone, gravel, and mineral extraction facilities.<\/p>\n <\/div>\n <\/div>\n\n <h3>2.2 Submersible and Water Applications<\/h3>\n\n <p>A significant feature of PROTOMONT NSHXOEU cables is their water resistance capability. According to the manufacturer’s specifications, these cables can be used permanently in waste water up to <span class=\"data-highlight\">40\u00b0C<\/span> at depths up to <span class=\"data-highlight\">500 meters<\/span>. They are also suitable for industrial water, cooling water, surface water, rainwater, mixed water, and to a more limited extent, groundwater and seawater applications.<\/p>\n\n <div class=\"info-box\">\n <h4>\ud83d\udccb Water Application Guidelines<\/h4>\n <p>At depths greater than 10 meters up to 500 meters, the requirements for accessibility and inspection are less stringent. In other respects, the specifications of DIN VDE 0298 Part 3 apply. For aggressive water or water containing special substances, cable resistance properties should be verified prior to installation.<\/p>\n <\/div>\n\n <h3>2.3 Industrial and Construction Applications<\/h3>\n\n <p>As documented by <a href=\"https:\/\/reelingcable.com\" rel=\"dofollow noopener\" class=\"external-link\" target=\"_blank\">Reeling Cable<\/a>, cables designed for mobile machinery must demonstrate high tensile strength combined with resistance to environmental factors and advanced insulation systems. The PROTOMONT NSHXOEU construction addresses these requirements through its multi-layer design featuring Class 5 flexible stranded conductors, EPR insulation, and EVA-based protective sheath.<\/p>\n\n <p>Technical sources indicate that these cables are used for connection of mobile equipment and machines in dry and damp areas, outdoors, and in explosion hazard areas\u2014particularly in mining, at quarries, and on building sites where medium mechanical loads are anticipated.<\/p>\n <\/section>\n\n <!-- Section 3: Characteristics -->\n <section id=\"characteristics\">\n <h2>3.

The tinning process provides corrosion protection while the fine stranding delivers superior flexibility for dynamic and mobile applications.<\/p>\n\n <table class=\"spec-table\">\n <thead>\n <tr>\n <th>Conductor Property<\/th>\n <th>Specification<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Material<\/td>\n <td>Electrolytic Copper, Tinned<\/td>\n <\/tr>\n <tr>\n <td>Stranding Class<\/td>\n <td>Class 5 (Finely Stranded) per DIN VDE 0295 \/ IEC 60228<\/td>\n <\/tr>\n <tr>\n <td>Maximum Tensile Load<\/td>\n <td>15 N\/mm\u00b2<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n <p>As noted by <a href=\"https:\/\/www.miningcable.cl\/cable-minero-shd-gc-con-led-autoalimentado-y-cubierta-tpu-rendimiento-y-seguridad-para-mineria-en-chile-y-peru\" rel=\"dofollow noopener\" class=\"external-link\" target=\"_blank\">Mining Cable Chile<\/a>, flexible bare copper conductors made from soft, high-quality copper provide excellent conductivity and flexibility essential for mining equipment applications.<\/p>\n\n <h3>4.2 Insulation System (PROTOLON)<\/h3>\n\n <p>The insulation utilizes PROTOLON, an EPR-based compound designated as Type 3GI3 per DIN VDE 0207. Ethylene Propylene Rubber (EPR) provides excellent electrical insulation properties combined with thermal stability and moisture resistance.<\/p>\n\n <table class=\"spec-table\">\n <thead>\n <tr>\n <th>Insulation Property<\/th>\n <th>Specification<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Trade Name<\/td>\n <td>PROTOLON<\/td>\n <\/tr>\n <tr>\n <td>Base Material<\/td>\n <td>EPR (Ethylene Propylene Rubber)<\/td>\n <\/tr>\n <tr>\n <td>Compound Type<\/td>\n <td>3GI3 per DIN VDE 0207<\/td>\n <\/tr>\n <tr>\n <td>Temperature Rating<\/td>\n <td>90\u00b0C continuous, 250\u00b0C short-circuit<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n <h3>4.3 Core Identification<\/h3>\n\n <p>Core identification follows DIN VDE 0293-308 standards. Cables with up to 5 cores feature color-coded identification, while cables with 6 or more cores use light-colored insulation with black numbers for identification.<\/p>\n\n <h3>4.4 Inner Sheath<\/h3>\n\n <p>For multi-core cables, an inner sheath constructed from vulcanized rubber compound (EPR base material, GM1B type per DIN VDE 0207) provides additional mechanical protection and maintains core positioning. Single-core cables do not incorporate an inner sheath.<\/p>\n\n <h3>4.5 Outer Sheath (EVA-Based 5GM3)<\/h3>\n\n <p>The outer sheath consists of vulcanized rubber compound based on EVA (Ethylene Vinyl Acetate), designated as Compound Type 5GM3 per DIN VDE 0207. This compound provides flame retardancy, oil resistance, and good flexibility while offering a halogen-reduced alternative to traditional chlorinated compounds. The standard color is yellow for high visibility.<\/p>\n\n <table class=\"spec-table\">\n <thead>\n <tr>\n <th>Outer Sheath Property<\/th>\n <th>Specification<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Base Material<\/td>\n <td>EVA (Ethylene Vinyl Acetate)<\/td>\n <\/tr>\n <tr>\n <td>Compound Type<\/td>\n <td>5GM3 per DIN VDE 0207<\/td>\n <\/tr>\n <tr>\n <td>Standard Color<\/td>\n <td>Yellow<\/td>\n <\/tr>\n <tr>\n <td>Flame Retardancy<\/td>\n <td>Per DIN EN 60332-1-2<\/td>\n <\/tr>\n <tr>\n <td>Oil Resistance<\/td>\n <td>Per DIN EN 60811-2-1<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n <div class=\"highlight-box\">\n <p><strong>EVA vs. CPE Sheath Comparison:<\/strong> The 5GM3 EVA-based compound in NSHXOEU cables offers halogen-reduced properties compared to the 5GM5 CPE\/chlorinated compound used in NSSHOEU cables.
