The voltage, insulation dimensions, core arrangement and accessories must be shown in the exact product file.<\/p><\/div>\n <div class=\"box\"><h3>Does \u201cSWA\u201d apply to single-core AC cable?<\/h3><p>Normally no. Single-core AC cables generally use non-magnetic AWA to avoid armour-induced current and heating. Confirm the circuit arrangement before accepting a SWA wording.<\/p><\/div>\n <div class=\"box\"><h3>Is BS 5467 XLPE\/SWA\/PVC the same as BS 6724?<\/h3><p>No. BS 5467 is the PVC-sheathed armoured route. BS 6724 is the low-smoke, low-corrosive-gas route. They require different material and fire-performance evidence.<\/p><\/div>\n <div class=\"box\"><h3>Can BS 5467 cable be buried directly?<\/h3><p>It can be suitable for direct burial in appropriate free-draining ground when the product and installation design allow it. Calculate the buried rating and protect the cable from mechanical and environmental damage.<\/p><\/div>\n <div class=\"box\"><h3>What is the current rating of 4-core 35 mm\u00b2?<\/h3><p>There is no single answer without installation method, ambient, grouping, soil or duct conditions and the permitted conductor temperature. Request the exact manufacturer schedule or perform the installation calculation.<\/p><\/div>\n <div class=\"box\"><h3>Can it be used on a crane reel or festoon?<\/h3><p>Not on the BS 5467 name alone. Reeling and festoon cables need a dynamic-duty design, flexing life, bend radius, tensile limits and application-specific validation.<\/p><\/div>\n <div class=\"box\"><h3>Does PVC mean the cable is LSZH or B2ca?<\/h3><p>No. PVC and LSZH are different sheath systems, and CPR classes are product-specific. Ask for the exact classification report and conformity documents.<\/p><\/div>\n <div class=\"box\"><h3>Is BS 5467 automatically fire resistant?<\/h3><p>No. The standard\u2019s basic flame-propagation reference is not the same as circuit integrity or LSZH performance. If the project needs fire survival, smoke control or circuit integrity, specify the relevant cable construction and test evidence separately.<\/p><\/div>\n <div class=\"box\"><h3>Can Feichun manufacture a replacement?<\/h3><p>Yes. Feichun can produce an independently engineered functional equivalent with its own drawing, dimensions, tests, marking, traceability and applicable certificate scope.<\/p><\/div>\n <\/div>\n <p class=\"formula\">FAQ configuration checklist\nLegacy \/ requested wording: [BS 5467 XLPE SWA PVC]\nRated voltage U\u2080\/U: [0.6\/1 kV or 1.9\/3.3 kV]\nConductor: [copper \/ confirmed alternative] \u00b7 cores: [number] \u00b7 cross-section: [mm\u00b2]\nConstruction: [CU\/XLPE\/PVC\/SWA\/PVC or CU\/XLPE\/PVC\/AWA\/PVC]\nInstallation: [tray \/ air \/ buried duct \/ direct burial \/ building \/ plant]\nEnvironment: [UV \/ oil \/ water \/ chemical \/ corrosion \/ fire-performance requirement]\nRequired data: OD, mass, resistance, current rating basis, voltage drop, bend radius,\nshort-circuit conductor and armour withstand, marking, tests and destination certificates<\/p>\n <p>The open fields are deliberate.
