Standard industrial cables quickly fail under these abrasive and high-tension conditions. Manufactured to rigorous SANS 1520-2 specifications, the <strong>Type 622 mining cable<\/strong> (and its ECC variant) is engineered specifically for these demanding reeling and trailing operations, delivering uncompromising power continuity and personnel safety.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-1286\" src=\"https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application.jpg\" alt=\"Black flexible Type 622 mining cable 12.7\/22kV for open cast mining draglines\" width=\"1000\" height=\"563\" srcset=\"https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application.jpg 1672w, https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application-300x169.jpg 300w, https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application-1024x576.jpg 1024w, https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application-768x432.jpg 768w, https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application-1536x864.jpg 1536w, https:\/\/tebaoflex-cable.com\/wp-content\/uploads\/2026\/06\/Type-622-Mining-Cable-application-600x338.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h3>Key Engineering Advantages<\/h3>\n<ul>\n<li><strong>Advanced Medium Voltage Insulation:<\/strong> To safely manage 12.7\/22 kV, the phase conductors feature a triple-extruded, strippable semi-conducting core screen and Ethylene Propylene Rubber (EPR) thermosetting compound. This advanced extrusion process eliminates micro-voids, preventing partial discharges and extending the cable&#8217;s electrical lifespan in hazardous areas.<\/li>\n<li><strong>Maximum Torsional Protection:<\/strong> Draglines and motorized reels subject cables to immense twisting forces. We engineer this cable with an open nylon reinforcing braid (minimum 16 strings). Crucially, the inner and outer Polychloroprene (CR) sheaths are heavily bonded together through this braid, creating a unified, torsion-resistant barrier that prevents internal core corkscrewing.<\/li>\n<li><strong>Individual Core Screening for Earth-Fault Safety:<\/strong> Each power core is individually screened with a tinned copper braid. In the event of crushing or penetration by mining equipment, this screen ensures a symmetrical earth fault, instantly triggering substation protection relays before a lethal external arc or fire can occur.<\/li>\n<li><strong>Rugged Environmental Defenses:<\/strong> Open cast mining exposes infrastructure to severe weather. The heavy-duty CR outer sheath is inherently flame retardant, highly resistant to tearing and abrasion, and engineered to withstand prolonged exposure to UV, direct sunlight, ozone, and industrial oils.<\/li>\n<\/ul>\n<h3>Technical Specifications<\/h3>\n<p>Manufactured in strict accordance with SANS 1520-2, SANS 1411-1, and SANS 1411-3 standards.

In the <strong>Type 622-ECC (Earth Continuity Conductor)<\/strong> variant, one of these pilot cores is replaced with an uninsulated, tinned copper earth conductor. The ECC variant provides an additional, highly conductive path for earth-fault currents, which is required by certain mining safety regulations depending on your specific equipment and substation setup.<\/p>\n<p><strong>Q2: Why is the minimum bending radius larger (9 x OD) compared to low-voltage cables?<\/strong> <strong>A:<\/strong> This is a 12.7\/22 kV medium voltage cable. Bending it too sharply can compress the triple-extruded EPR insulation and the semi-conducting screens, potentially causing localized electrical stress and partial discharges. The 9 x Overall Diameter bending radius ensures the internal geometry remains perfectly intact during reeling, maximizing the cable&#8217;s high-voltage lifespan.<\/p>\n<p><strong>Q3: How does the &#8220;bonded inner and outer sheath&#8221; improve performance on a dragline?<\/strong> <strong>A:<\/strong> Draglines pull cables over long distances, introducing severe friction and twisting. If the inner and outer sheaths are separate, the outer jacket can slip or stretch independently, causing the internal cores to buckle. By securely bonding the CR inner sheath, the nylon reinforcing braid, and the CR outer sheath together, we create a unified solid structure. This prevents sheath slippage and provides exceptional torsional protection.<\/p>\n<p><strong>Q4: Can TEBAOFLEX provide these cables on specialized steel drums for immediate site deployment?<\/strong> <strong>A:<\/strong> Yes. As a direct manufacturer, we supply global mining EPCs and operators. We offer standard 500-meter lengths on heavy-duty wooden or steel drums, depending on your logistical requirements. Other forms of packing and custom delivery lengths are readily available upon request to minimize splicing on your mining site.<\/p>\n<p><!-- tebaoflex-p1-mining-links --><\/p>\n<p class=\"tf-p1-mining-links\"><strong>Continue the mining cable selection:<\/strong> For the full <a href=\"\/products\/mining-tunneling-cables\/\">Mining &amp; Tunneling Cables<\/a> range and application guidance, see <a href=\"\/solutions\/mining-tunneling\/\">Mining and Tunneling Cable Solutions<\/a>.
