Manufactured by Anhui Feichun Special Cable Co., Ltd., this cable series delivers reliable power transmission across voltage ratings from 3.6\/6 kV to 18\/30 kV, making it indispensable for large-scale mining operations, conveyor systems, and heavy material handling equipment.<\/p>\n \n <p>Unlike standard reeling cables designed for high-speed dynamic applications, the “F” designation in PROTOLON(M) F indicates this series is optimized for fixed and semi-flexible installations. This makes it particularly suited for permanent laying alongside conveyor belts, shiftable mining units, connections between upper and lower machinery sections (such as excavator car bodies), and continuous submersible pump operations.<\/p>\n \n <div class=\"highlight-box\">\n <h4>Key Differentiator<\/h4>\n <p>The PROTOLON F series is engineered for applications involving continuous slight movements during operation, including vibrations, free sag, and minor twisting during machinery rotation. This distinguishes it from the PROTOLON R series designed for high-speed reeling applications up to 240 m\/min. According to industry specifications based on <a href=\"https:\/\/www.elandcables.com\/electrical-cable-and-accessories\/cables-by-standard\/vde0250-cable\" class=\"reference-link\" rel=\"nofollow noopener\" target=\"_blank\">DIN VDE 0250-813<\/a>, this standard represents the benchmark for tough rubber-sheathed flexible reeling cables globally.<\/p>\n <\/div>\n \n <h2 id=\"purpose\">Purpose and Primary Applications<\/h2>\n \n <p>The PROTOLON(M) F (N)TSCGEWOEU cable serves multiple critical functions in industrial power distribution. Its primary applications encompass permanent installation alongside conveyor belt systems in both static and shiftable configurations, power delivery to material handling equipment experiencing continuous but limited movement, and interconnection between mobile machinery sections such as excavator superstructures and undercarriages.<\/p>\n \n <p>A distinctive capability of this cable series is its suitability for submersible pump applications. The cable construction supports continuous operation in water environments, enabling reliable power supply to pumping equipment in mining dewatering operations and similar submerged installations. This versatility addresses the complex power distribution requirements found in modern open-cast mining operations, where equipment configurations often combine static and mobile power requirements. For comprehensive guidance on selecting appropriate cables for various mining scenarios, industry professionals can reference technical resources from established suppliers such as <a href=\"https:\/\/www.amplexmining.com.au\/cable-selection-in-mining-operations-a-comprehensive-guide\" class=\"reference-link\" target=\"_blank\" rel=\"noopener\">amplexmining.com.au<\/a> and <a href=\"https:\/\/www.reelingcable.com\/crane-cable\" class=\"reference-link\" target=\"_blank\" rel=\"noopener\">reelingcable.com<\/a>.<\/p>\n \n <h3>Industry Sectors Served<\/h3>\n \n <div class=\"spec-grid\">\n <div class=\"spec-card\">\n <h4>Open-Cast Mining<\/h4>\n <p>Powers large excavators, stackers, reclaimers, and mobile crushers in strip mining and open-pit operations where equipment operates across extensive travel distances.<\/p>\n <\/div>\n <div class=\"spec-card\">\n <h4>Conveyor Systems<\/h4>\n <p>Provides reliable power along permanent and shiftable conveyor belt installations transporting bulk materials across mining sites and processing facilities.<\/p>\n <\/div>\n <div class=\"spec-card\">\n <h4>Material Handling<\/h4>\n <p>Supports connections to mobile cranes, dumpers, and transfer equipment requiring flexible yet stable power delivery during operational movements.<\/p>\n <\/div>\n <div class=\"spec-card\">\n <h4>Pump Systems<\/h4>\n <p>Enables continuous submerged operation for dewatering pumps and submersible pump units in water management applications.<\/p>\n <\/div>\n <\/div>\n \n <h2 id=\"characteristics\">Technical Characteristics<\/h2>\n \n <p>The engineering specifications of PROTOLON(M) F (N)TSCGEWOEU cables reflect decades of development in high-performance industrial cable technology.

Each component serves specific functions within the overall cable architecture.<\/p>\n \n <h3>Conductor System<\/h3>\n \n <p>The conductor consists of electrolytic copper in an untinned, very finely stranded configuration conforming to Class 5 standards. This stranding approach maximizes flexibility while maintaining excellent current-carrying capacity. Conductor cross-sections range from 25 mm\u00b2 to 300 mm\u00b2, with corresponding current ratings from 131 A to 620 A at 30\u00b0C ambient temperature for surface-laid installations.<\/p>\n \n <div class=\"highlight-box success\">\n <h4>Conductor Resistance Comparison<\/h4>\n <p>At 20\u00b0C, conductor resistance values range from 0.78 \u03a9\/km for 25 mm\u00b2 sections down to 0.0641 \u03a9\/km for 300 mm\u00b2 sections. These values ensure efficient power transmission with minimal losses, critical for long cable runs typical in mining applications. The relationship between conductor size and resistance follows established engineering principles, with resistance inversely proportional to cross-sectional area.<\/p>\n <\/div>\n \n <h3>Insulation System<\/h3>\n \n <p>The primary insulation employs PROTOLON compound, a specialized formulation based on Ethylene Propylene Rubber (EPR). The compound type designation “better 3GI3” indicates enhanced performance characteristics exceeding standard EPR formulations. This material selection provides superior dielectric strength, flexibility retention across temperature extremes, and resistance to environmental degradation.<\/p>\n \n <p>Electrical field control is achieved through dual semiconductive rubber compound layers positioned at both inner and outer insulation boundaries. This construction ensures uniform electric field distribution, preventing localized stress concentrations that could lead to premature insulation breakdown. The semiconductive layers enable controlled voltage gradients within the cable structure.<\/p>\n \n <h3>Core Configuration<\/h3>\n \n <p>The cable architecture features three main conductors in a laid-up configuration, with the protective earth conductor split into three parts positioned within the outer interstices. This arrangement optimizes the cable’s cross-sectional geometry while ensuring effective fault current paths. Core identification utilizes natural coloring with black semiconductive rubber, supplemented by white printed digits (1, 2, 3) for phase identification.<\/p>\n \n <h3>Sheath System<\/h3>\n \n <table>\n <thead>\n <tr>\n <th>Component<\/th>\n <th>Material<\/th>\n <th>Compound Type<\/th>\n <th>Function<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Inner Sheath<\/td>\n <td>EPR-based compound<\/td>\n <td>Special compound<\/td>\n <td>Mechanical protection, core binding<\/td>\n <\/tr>\n <tr>\n <td>Outer Sheath<\/td>\n <td>Synthetic elastomer (CM)<\/td>\n <td>Better 5GM3<\/td>\n <td>Environmental protection, abrasion resistance<\/td>\n <\/tr>\n <tr>\n <td>Sheath Color<\/td>\n <td colspan=\"3\">Red (standard)<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n \n <h2 id=\"standards\">Standards Compliance and Certifications<\/h2>\n \n <p>Adherence to recognized international and regional standards ensures consistent product quality and regulatory acceptance across global markets. The PROTOLON(M) F (N)TSCGEWOEU cable series maintains compliance with multiple certification frameworks. As noted by <a href=\"https:\/\/www.cranecable.com.au\/type-455-33-to-33kv-reeling-and-trailing-cable-engineering-excellence-for-stacker-reclaimer-applications\" class=\"reference-link\" target=\"_blank\" rel=\"noopener\">cranecable.com.au<\/a>, standards compliance provides operators with confidence that cables will perform reliably under the demanding conditions typical of industrial material handling.<\/p>\n \n <h3>Primary Standard<\/h3>\n \n <p>The cable design is based on DIN VDE 0250-813, the German national standard governing cables, wires, and flexible cords for power installations, specifically addressing trailing cable requirements. Germany remains the only country to have issued comprehensive design regulations specifically for flexible electrical cables serving cranes and material handling equipment, establishing DIN VDE 0250 as the de facto global benchmark for tough rubber-sheathed flexible cables.<\/p>\n \n <h3>Certifications and Approvals<\/h3>\n \n <div class=\"spec-grid\">\n <div class=\"spec-card\">\n <h4>Russian Federation<\/h4>\n <div class=\"spec-item\">\n <span class=\"spec-label\">Fire Certificate<\/span>\n <span class=\"spec-value\">Certified<\/span>\n <\/div>\n <div class=\"spec-item\">\n <span class=\"spec-label\">GOST-R<\/span>\n <span class=\"spec-value\">Approved<\/span>\n <\/div>\n <div class=\"spec-item\">\n <span class=\"spec-label\">GOST-K<\/span>\n <span class=\"spec-value\">Approved<\/span>\n <\/div>\n <div class=\"spec-item\">\n <span class=\"spec-label\">GOST-B<\/span>\n <span class=\"spec-value\">Approved<\/span>\n <\/div>\n <\/div>\n <div class=\"spec-card\">\n <h4>Test Standards<\/h4>\n <div class=\"spec-item\">\n <span class=\"spec-label\">Fire Test<\/span>\n <span class=\"spec-value\">IEC 60332-1-2<\/span>\n <\/div>\n <div class=\"spec-item\">\n <span class=\"spec-label\">Oil Resistance<\/span>\n <span class=\"spec-value\">IEC 60811-404<\/span>\n <\/div>\n <div class=\"spec-item\">\n <span class=\"spec-label\">Weather\/Water<\/span>\n <span class=\"spec-value\">EN 50525-2-21<\/span>\n <\/div>\n <\/div>\n <\/div>\n \n <h2 id=\"safety\">Safety Thresholds and Thermal Parameters<\/h2>\n \n <p>Understanding operational limits ensures safe, reliable cable performance throughout its service life.

This parameter directly influences protection system coordination and should be considered when specifying protective devices. Short circuit current capacities range from 3.58 kA for 25 mm\u00b2 conductors to 42.9 kA for 300 mm\u00b2 conductors, enabling proper coordination with upstream protection equipment.<\/p>\n <\/div>\n \n <h3>Environmental Resistance<\/h3>\n \n <p>The cable construction provides comprehensive resistance to environmental factors common in mining and industrial environments. This includes unrestricted use in both outdoor and indoor installations, with certified resistance to ozone, ultraviolet radiation, and moisture per EN 50525-2-21 requirements. Oil resistance testing follows IEC 60811-404 protocols, ensuring compatibility with the hydraulic fluids and lubricants prevalent in mining equipment.<\/p>\n \n <h2 id=\"precautions\">Installation and Usage Precautions<\/h2>\n \n <p>Proper installation and operational practices maximize cable service life and ensure safe performance. The following guidelines address critical considerations for cable handling and installation.<\/p>\n \n <h3>Pre-Installation Requirements<\/h3>\n \n <p>Prior to installation, verify that environmental conditions fall within specified parameters. Installation should not proceed if ambient temperatures fall below -25\u00b0C, as cold conditions can temporarily reduce insulation flexibility and increase the risk of mechanical damage during handling. Allow sufficient time for cable temperature equalization if materials have been stored in significantly different temperature conditions.<\/p>\n \n <p>Assess the installation path for potential mechanical hazards including sharp edges, abrasive surfaces, and points of potential crushing or impact. Install appropriate protection measures such as cable troughs, protective conduits, or impact shields where hazards cannot be eliminated.<\/p>\n \n <h3>Handling Guidelines<\/h3>\n \n <p>Observe minimum bending radii as specified in DIN VDE 0298-3 throughout all handling operations. The minimum bending radius varies with cable diameter and construction, but generally exceeds 12 times the overall cable diameter for single bend operations. Multiple or repeated bending operations require larger radii to prevent cumulative fatigue damage.<\/p>\n \n <p>Avoid dragging cables over rough surfaces without appropriate protection. Although the outer sheath provides good abrasion resistance, excessive surface damage can compromise long-term environmental protection. Use appropriate lifting equipment and rolling techniques for handling cable drums.<\/p>\n \n <h3>Operational Considerations<\/h3>\n \n <p>When connecting to equipment experiencing continuous operational movement, ensure adequate cable length to accommodate the full range of motion without exceeding specified bending radii or tensile limits. The 15 N\/mm\u00b2 maximum tensile load specification should not be exceeded during any operational condition.<\/p>\n \n <p>For submersible pump applications, verify that cable entry glands and terminations maintain water integrity rated for the expected submersion depth and pressure. Regular inspection schedules should include verification of gland sealing effectiveness.<\/p>\n \n <h2 id=\"specifications\">Detailed Specifications by Voltage Class<\/h2>\n \n <h3>3.6\/6 kV Configuration Data<\/h3>\n \n <table>\n <thead>\n <tr>\n <th>Cross Section<\/th>\n <th>OD Min (mm)<\/th>\n <th>OD Max (mm)<\/th>\n <th>Weight (kg\/km)<\/th>\n <th>Max.
