class=\"body\" id=\"s1\">\n <h2>Introduction: One Cable Family, Every Festoon Function<\/h2>\n\n <p>BiTcrane<span class=\"tm\">\u00ae<\/span> (N)3GRD5G is not one cable\u2014it is an <strong>entire festoon cable system<\/strong>. With over 40 standard configurations spanning four distinct product families\u2014single-core power, multi-core control, three-phase motor power, and paired signal cables\u2014BiTcrane provides every cable type needed to build a complete crane festoon electrical system from a single manufacturer, a single specification, a single rubber compound system, and a single 240 m\/min speed rating.<\/p>\n\n <p>This breadth of range is BiTcrane’s defining advantage. When a crane manufacturer or festoon system integrator specifies a festoon cable system, they need multiple cable types: single-core cables for per-phase power distribution to large hoist and traverse motors; multi-core cables for control, interlock, and distribution circuits; three-phase cables with integrated earth for smaller motor drives; and paired cables for encoder feedback, sensor signals, and communication bus circuits. If these cables come from different manufacturers or different product families, they may have different mechanical properties, different bending radii, different speed ratings, and different rubber compounds\u2014creating compatibility issues when they are installed side by side in the same festoon trolley system.<\/p>\n\n <p>BiTcrane eliminates this problem entirely. Every configuration uses the same <strong>HEPR insulation, GM1b rubber inner sheath, and 5GM5 rubber outer sheath<\/strong>. Every configuration operates at the same <strong>240 m\/min festoon speed<\/strong>. Every configuration achieves the same <strong>4\u00d7 OD static and 5\u00d7 OD dynamic bending radius<\/strong>. Every configuration is engineered for the same <strong>unidirectional bending<\/strong> characteristic optimised for festoon trolley sheaves. A crane manufacturer can specify the entire festoon cable set from Feichun’s BiTcrane range with absolute confidence that all cables will operate compatibly in the same festoon system.<\/p>\n\n <div class=\"note amber\">\n <div class=\"nt\">BiTcrane vs. RONDOFLEX \/ Rheyfestoon<\/div>\n <p>BiTcrane (N)3GRD5G is the <strong>unscreened<\/strong> festoon cable family. For applications where EMC screening is not required\u2014contactor-driven cranes, cranes in low-EMI environments, or applications where separate screened cables are used only for sensitive signal circuits\u2014BiTcrane provides the complete cable system at significantly lower cost than the screened RONDOFLEX (C)-FC and Rheyfestoon alternatives. For VFD-intensive environments requiring full EMC compliance, specify the screened RONDOFLEX\/Rheyfestoon pair for motor power and sensitive signals, and BiTcrane for non-sensitive power distribution and general control circuits.<\/p>\n <\/div>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s2\">\n <h2>Technical Anatomy: Full Specification Breakdown<\/h2>\n\n <div class=\"tw\">\n <table>\n <caption>BiTcrane\u00ae (N)3GRD5G Technical Specifications (VDE 0250-812)<\/caption>\n <thead><tr><th>Parameter<\/th><th>Specification<\/th><\/tr><\/thead>\n <tbody>\n <tr><td>Standard<\/td><td><strong>VDE 0250-812<\/strong> (with ref. to).

EMC screening adds significant cost (the tinned copper braid material alone represents 15\u201325% of the cable’s total cost), reduces cable flexibility (the braid adds a semi-rigid layer that increases bending stiffness), increases cable diameter (the braid and its synthetic fibre overlay add 2\u20134 mm to OD), and increases cable weight (copper braid adds 200\u2013500 g\/m depending on cable size).<\/p>\n\n <p>For applications where EMC screening is not required, specifying a screened cable is wasteful. And the majority of festoon cable applications do not require screening. Specifically, BiTcrane unscreened cables are the correct choice when the crane uses <strong>contactor-driven motors<\/strong> (which generate minimal EMI), when the crane’s <strong>VFD drives are located in the fixed electrical room<\/strong> (not on the moving crane structure, so the VFD output cables do not travel through the festoon), when the sensitive signal circuits have their <strong>own dedicated screened cables<\/strong> (e.g., a Rheyfestoon for encoder signals alongside BiTcrane for power and general control), or when the application is a <strong>conveyor or material handling system<\/strong> where EMC requirements are less stringent than crane systems.<\/p>\n\n <p>By selecting BiTcrane unscreened cables for power and general control functions\u2014and screened cables only for the specific circuits that require screening\u2014the total festoon cable system cost is optimised: screening investment goes precisely where it is needed, and the remaining circuits benefit from the lower cost, greater flexibility, and smaller diameter of unscreened construction.<\/p>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s8\">\n <h2>Also for Drag Chains and Conveyors: Beyond Festoon<\/h2>\n\n <p>Unlike the Rheyfestoon and RONDOFLEX cables that are exclusively festoon products, BiTcrane (N)3GRD5G is explicitly rated for <strong>drag chains and conveyor facilities<\/strong> in addition to festoon trolley systems. The cable’s unidirectional bending optimisation applies equally to drag chain operation (where the cable bends in one direction as the chain articulates) and to conveyor-mounted festoon systems (where cables travel with conveyor structures).<\/p>\n\n <p>This multi-application versatility makes BiTcrane the most broadly applicable festoon-grade cable in the Feichun catalogue. A single cable specification can serve the festoon system on a crane, the drag chain on an automated material handling system, and the conveyor-mounted cable management on a processing line\u2014simplifying procurement and reducing inventory complexity for facilities that operate all three types of equipment.<\/p>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s9\">\n <h2>Real-World Applications<\/h2>\n\n <h3>Complete Crane Festoon Systems<\/h3>\n <p>A typical medium-duty overhead crane festoon system uses: 3\u00d7 BiTcrane 1\u00d770 (hoist motor phases, 279 A each), 1\u00d7 BiTcrane 1\u00d750 (hoist earth, 216 A), 1\u00d7 BiTcrane 3\u00d725+3G16\/3 (traverse motor, 131 A), 1\u00d7 BiTcrane 5G6 (auxiliary power: brakes, lighting, 53 A), 1\u00d7 BiTcrane 18G1.5 (control and interlock, 23 A per core), 1\u00d7 BiTcrane 6\u00d7(2\u00d71)C (encoder and sensor signals).

The 5GM5 neoprene outer sheath withstands the heat radiation, metal dust, and aggressive atmosphere of steelmaking environments.<\/p>\n\n <h3>Automated Port Equipment<\/h3>\n <p>RMG cranes, ship loaders, and bulk conveyors use BiTcrane three-phase and multi-core configurations for non-VFD-output circuits: transformer supply, lighting distribution, heating, and general control functions. VFD motor output circuits use screened RONDOFLEX (C)-FC.<\/p>\n\n <h3>Conveyor Systems and Material Handling<\/h3>\n <p>Mining conveyors, aggregate processing lines, grain handling systems, and automotive manufacturing conveyors use BiTcrane for drive power and control distribution through cable trolley systems mounted on the conveyor structure.

Klaus Faber quoted \u00a532 million annually with 12-week lead time. Feichun quoted \u00a516 million with 4-week lead time using FC-FLX\u2122 conductors across all 40+ configurations. Annual savings: \u00a516 million (approximately \u20ac2 million). The crane manufacturer reports zero field cable failures across 400+ cranes delivered with Feichun BiTcrane cables over 24 months of production.<\/p>\n <\/div>\n\n <\/section>\n\n \n <section class=\"body\" id=\"s11\">\n <h2>Technical FAQ<\/h2>\n\n <h3>Can BiTcrane be used on VFD motor output circuits?<\/h3>\n <p>BiTcrane’s 2.5 kV test voltage is adequate for 400 V VFD systems with cable lengths under 25 metres (where reflected-wave peak voltage stays below approximately 1,200 V). For 690 V VFD systems or 400 V systems with cable lengths exceeding 25 metres, use RONDOFLEX (C)-FC with its 5 kV test voltage and semi-conductive stress-control insulation. BiTcrane is not recommended for VFD motor output circuits in general\u2014it is designed primarily for contactor-switched power, control, and signal circuits.<\/p>\n\n <h3>Why does the three-phase configuration use split earth (“\/3”) while the multi-core uses standard earth (“G”)?<\/h3>\n <p>Three-phase configurations carry significantly higher fault currents that require equalised earth return paths\u2014the split-earth interstices design provides this. Multi-core configurations carry lower currents where a single earth conductor provides adequate fault protection. The “\/3” split-earth design also maintains the cable’s round cross-section, which is important for the larger three-phase cables that experience higher radial forces in the festoon trolley system.<\/p>\n\n <h3>What is the maximum festoon span length for BiTcrane?<\/h3>\n <p>Maximum festoon span depends on cable weight, trolley spacing, and acceptable catenary sag. For the 1\u00d7185 cable (1,968 kg\/km), typical trolley spacing is 2.5\u20134 metres with acceptable sag of 150\u2013300 mm. For lighter cables (5G1.5 at 245 kg\/km), trolley spacing can extend to 4\u20136 metres. Feichun provides festoon span calculation tools and trolley spacing recommendations for each configuration on request.<\/p>\n\n <h3>Can Feichun supply additional configurations beyond the standard 40+?<\/h3>\n <p>Yes. Feichun manufactures custom BiTcrane-equivalent configurations including non-standard core counts, non-standard cross-sections, composite power+control cables, and configurations with additional features (overall foil screen, drain wire, special core identification). Custom configurations: 6\u201310 week lead time.<\/p>\n\n <\/section>\n\n \n <section class=\"refs\" id=\"s12\">\n <h2>References and Standards<\/h2>\n <ol class=\"rl\">\n <li>Anhui Feichun Special Cable Co., Ltd., <em>BiTcrane\u00ae (N)3GRD5G Festoon Cable Family \u2014 Technical Data Sheet<\/em>, Rev. 2.0, 2026.<\/li>\n <li>Klaus Faber AG, <em>BiTcrane\u00ae (N)3GRD5G-J\/O \u2014 Product Data Sheet<\/em>, dbl_n3grd5g_bit.pdf, Issue 04\/01\/2026.<\/li>\n <li>VDE 0250-812, <em>Flexible cables for festoon and trolley systems under mechanical stress<\/em>.<\/li>\n <li>VDE 0298-3, <em>Bending radii for flexible cables<\/em>.<\/li>\n <li>DIN VDE 0298-4, <em>Current carrying capacity for cables<\/em>.<\/li>\n <li>IEC 60332-1-2, <em>Vertical flame propagation test<\/em>.<\/li>\n <li>EN 60811-404, <em>Mineral oil immersion test<\/em>.<\/li>\n <li>IEC 60228, <em>Conductors of insulated cables<\/em>.<\/li>\n <li>GB\/T 467, <em>Cathode copper<\/em>.<\/li>\n <\/ol>\n <\/section>\n\n <div class=\"contact\">\n <h3>Contact Anhui Feichun Special Cable Co., Ltd. \u2014 Complete Festoon Cable System Specialists<\/h3>\n <div class=\"cg\">\n <div class=\"ci\"><span class=\"lb\">Technical Specifications & Engineering<\/span><a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div>\n <div class=\"ci\"><span class=\"lb\">Procurement & Volume Orders<\/span><a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div>\n <div class=\"ci\"><span class=\"lb\">Emergency Support (24\/7)<\/span>+86 138 5608 5607<\/div>\n <div class=\"ci\"><span class=\"lb\">Technical WhatsApp & WeChat<\/span>+86 138 5512 3218<\/div>\n <\/div>\n <\/div>\n\n <footer class=\"ft\">\n <p>This technical guide is based on Feichun’s proprietary equivalent to the BiTcrane<span class=\"tm\">\u00ae<\/span> (N)3GRD5G festoon cable family, incorporating FC-FLX<span class=\"tm\">\u2122<\/span> Tongling copper conductors, HEPR insulation, GM1b inner sheath, and 5GM5 outer sheath.
