Port and mining engineers often search a voltage and a cable name first, then discover later that the dominant failure mechanism is mechanical rather than electrical: conductor work-hardening, sheath abrasion, tensile load, torsion or repeated bending.

Feichun\u2019s own technical library describes reel systems as a combined tensile, bending, torsional, UV, salt-spray and abrasion problem rather than a conventional fixed-cable problem. <a href=\"https:\/\/feichuncables.com\/blog\/tag\/crane-reeling-cable\/\" target=\"_blank\" rel=\"noopener\">[4]<\/a><\/p>\n\n<h3 id=\"nomenclature\">1.1 Nomenclature: how engineers should read the suffixes<\/h3>\n<table class=\"comparison-table\">\n<thead><tr><th>Marking<\/th><th>Engineering meaning<\/th><th>Material \/ fire strategy<\/th><th>Typical decision driver<\/th><\/tr><\/thead>\n<tbody>\n<tr><td><strong>\u0410\u0441\u0412\u0412\u0413<\/strong><\/td><td>Aluminum-alloy conductor; PVC insulation; PVC sheath<\/td><td>Baseline PVC<\/td><td>Fixed routes where single-cable flame limitation is acceptable<\/td><\/tr>\n<tr><td><strong>\u0410\u0441\u0412\u0412\u0413\u043d\u0433(\u0410)<\/strong><\/td><td>As above, with reduced-flammability compound<\/td><td>Grouped flame propagation Category A<\/td><td>Cable galleries, grouped industrial routes<\/td><\/tr>\n<tr><td><strong>\u2026-LS<\/strong><\/td><td>Low smoke \/ reduced fire hazard<\/td><td>Reduced smoke and gas evolution<\/td><td>Enclosed spaces where visibility and smoke burden matter<\/td><\/tr>\n<tr><td><strong>\u2026-LSLTx<\/strong><\/td><td>Low smoke + low toxicity<\/td><td>Reduced toxicity of combustion products<\/td><td>Hospitals, schools, care facilities, sleeping accommodation<\/td><\/tr>\n<tr><td><strong>\u0410\u0441\u041f\u041f\u0413\u043d\u0433(\u0410)-HF<\/strong><\/td><td>Halogen-free polymer insulation\/sheath family<\/td><td>Low corrosivity \/ halogen-free strategy<\/td><td>Occupied or equipment-dense interiors where corrosive gases are a major hazard<\/td><\/tr>\n<tr><td><strong>\u201c-\u041f\u201d<\/strong><\/td><td>Flat construction<\/td><td>Same fire suffix logic, altered geometry<\/td><td>Low-profile fixed routing and planar installation constraints<\/td><\/tr>\n<\/tbody>\n<\/table>\n\n<div class=\"citation-box\"><strong>Why \u201c\u043d\u0433(\u0410)\u201d is more than a marketing suffix:<\/strong> IEC 60332-3-22 Category A evaluates vertical flame spread on bunched cables using a high non-metallic material loading (7 L\/m) and a 40-minute flame application.

IEC 61238-1-1 explicitly covers compression and mechanical connectors for power cables up to 1 kV and includes aluminum conductors across substantial cross-section ranges. <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/29515\" target=\"_blank\" rel=\"noopener\">[7]<\/a><\/p>\n\n<div class=\"tech-highlight\">\n<h4>Feichun engineering emphasis: conductor \/ connector \/ route as one system<\/h4>\n<p>For project engineering, \u201csame mm\u00b2\u201d is not a sufficient substitution rule between copper, conventional aluminum and aluminum-alloy conductors. A professional substitution review should check conductor DC resistance, permissible current under the actual route, voltage drop, short-circuit duty, terminal lug compatibility, thermal expansion, installation pulling load, support spacing and fire class.

For four-core cables with equal conductor sections in four-wire networks loaded in all conductors during normal operation, and for five-core cables, the supplied values require multiplication by <strong>0.93<\/strong>. Where real installation conditions differ, correction factors or a project-specific thermal calculation are required. IEC 60287-1-1 provides the international calculation framework for steady-state cable current ratings and losses. <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/68118\" target=\"_blank\" rel=\"noopener\">[11]<\/a><\/p>\n\n<table>\n<thead><tr><th>Nominal section<br>mm\u00b2<\/th><th>Single-core DC<br>A<\/th><th>Single-core AC<br>A*<\/th><th>Multicore AC<br>A**<\/th><th>1 s short-circuit<br>kA<\/th><th>Insulation resistance<br>M\u03a9\u00b7km min.<\/th><\/tr><\/thead>\n<tbody><tr><td>2.5<\/td><td>30<\/td><td>22<\/td><td>21<\/td><td>0.18<\/td><td>12.0<\/td><\/tr>\n<tr><td>4<\/td><td>40<\/td><td>30<\/td><td>29<\/td><td>0.29<\/td><td>10.1<\/td><\/tr>\n<tr><td>6<\/td><td>51<\/td><td>37<\/td><td>37<\/td><td>0.42<\/td><td>8.7<\/td><\/tr>\n<tr><td>10<\/td><td>69<\/td><td>50<\/td><td>50<\/td><td>0.70<\/td><td>7.1<\/td><\/tr>\n<tr><td>16<\/td><td>93<\/td><td>68<\/td><td>67<\/td><td>1.13<\/td><td>5.8<\/td><\/tr>\n<tr><td>25<\/td><td>117<\/td><td>92<\/td><td>87<\/td><td>1.81<\/td><td>5.6<\/td><\/tr>\n<tr><td>35<\/td><td>143<\/td><td>113<\/td><td>106<\/td><td>2.50<\/td><td>4.9<\/td><\/tr>\n<tr><td>50<\/td><td>176<\/td><td>139<\/td><td>126<\/td><td>3.38<\/td><td>4.8<\/td><\/tr>\n<tr><td>70<\/td><td>223<\/td><td>176<\/td><td>161<\/td><td>4.95<\/td><td>4.1<\/td><\/tr>\n<tr><td>95<\/td><td>275<\/td><td>217<\/td><td>197<\/td><td>6.86<\/td><td>4.1<\/td><\/tr>\n<tr><td>120<\/td><td>320<\/td><td>253<\/td><td>229<\/td><td>8.66<\/td><td>3.7<\/td><\/tr>\n<tr><td>150<\/td><td>366<\/td><td>290<\/td><td>261<\/td><td>10.64<\/td><td>3.7<\/td><\/tr>\n<tr><td>185<\/td><td>425<\/td><td>336<\/td><td>302<\/td><td>13.37<\/td><td>3.7<\/td><\/tr>\n<tr><td>240<\/td><td>508<\/td><td>401<\/td><td>359<\/td><td>17.54<\/td><td>3.6<\/td><\/tr>\n<tr><td>300<\/td><td>589<\/td><td>464<\/td><td>424<\/td><td>21.90<\/td><td>3.5<\/td><\/tr>\n<tr><td>400<\/td><td>693<\/td><td>544<\/td><td>501<\/td><td>26.00<\/td><td>3.3<\/td><\/tr>\n<tr><td>500<\/td><td>819<\/td><td>636<\/td><td>\u2014<\/td><td>32.50<\/td><td>3.2<\/td><\/tr>\n<tr><td>630<\/td><td>971<\/td><td>744<\/td><td>\u2014<\/td><td>40.95<\/td><td>2.9<\/td><\/tr>\n<tr><td>800<\/td><td>1146<\/td><td>858<\/td><td>\u2014<\/td><td>52.00<\/td><td>2.6<\/td><\/tr><\/tbody>\n<\/table>\n<p class=\"small\">* Supplied table: single-core AC installation in touching trefoil formation. ** For four-core equal-section four-wire systems loaded in all cores, and for five-core cables, multiply applicable multicore current values by 0.93.
