Installation damage (bent too sharply during installation)\n\nWith single core (LIFT-1S UL):\n  Failure: Core breaks\n  Consequence: Cable loses mechanical strength\n  Load transfer: Copper conductors must carry full load\n  Result: Copper exceeds safe stress, insulation failure possible\n  Safety fallback: Control circuit must function to lower equipment safely\n  Risk: If control circuit also failed, catastrophic failure\n  \nWith dual cores (LIFT-2S UL):\n  Failure: One core breaks\n  Consequence: Other core carries full load (designed for this)\n  Load distribution: Stress on remaining core: 100% (vs. 50% nominal)\n  Result: Still within safety margin (design allows for single-core failure)\n  Safety fallback: Mechanical backup works independent of electrical system\n  Risk: Extremely low (two cores would need simultaneous failure)\n\nDesign safety factor:\n\nSingle core sizing (LIFT-1S UL):\n  Load requirement: Support 50 kg equipment + 5 kg cable = 55 kg\n  Stress on core: 55 kg \u00f7 core area = X stress\n  Design factor: 5\u00d7 safety margin\n  Available stress capacity: 5\u00d7 \u00d7 X = 5\u00d7 load capacity\n  \nDual core sizing (LIFT-2S UL):\n  Load requirement: Same 55 kg\n  Stress per core (nominal): 27.5 kg \u00f7 (2\u00d7 core area) = (X\/2) stress\n  Design factor per core: 5\u00d7 safety margin\n  Available stress capacity per core: 5\u00d7 \u00d7 (X\/2) = 2.5\u00d7 load capacity\n  If one core fails: Remaining core carries 55 kg with 2.5\u00d7 safety (still safe)\n  Result: Single-core failure doesn&#8217;t exceed material limits\n\nLoad distribution (stress concentration):\n\nSingle core cable bending:\n  Bending stress = E\u00d7I \/ R (proportional to moment of inertia)\n  If core is centered: Bending moment concentrated at single location\n  Risk: Stress concentration at core boundary\n  \nDual core configuration:\n  Cores offset slightly (symmetrical placement)\n  Bending stress distributed across two locations\n  Result: Lower stress at each core, less cracking risk\n  Benefit: Fatigue life improved vs. single core\n\nNylon covering (protection of dual cores):\n\nWhy nylon over both cores?\n  Purpose: Protect galvanizing from interior moisture\n  Applied to both cores individually (or as pair assembly)\n  Coverage: Black nylon sheath ~0.5\u20131 mm per core\n  Result: Both cores protected equally, extended life\n\nFailure mode if nylon compromised:\n  One core galvanizing damaged: Corrosion affects only that core\n  Other core still protected: Maintains mechanical function\n  Safety consequence: System continues working at reduced capacity\n  Probability: Very low (would need both nylon sheaths damaged)\n\nCost-benefit of dual cores:\n\nMaterial cost increase:\n  Single core: ~$0.50\u20131.00 per meter (material only)\n  Dual cores: ~$1.00\u20132.00 per meter (+50\u2013100% material cost)\n  For 500 m elevator run: ~$250\u2013500 additional cost\n\nValue provided:\n  Mechanical backup worth: ~$5,000\u201320,000 (cost of elevator failure\/replacement cable)\n  ROI: Extremely high (prevent catastrophic failure)\n  Insurance benefit: May reduce premiums (redundancy appreciated by underwriters)\n\nLong-term reliability perspective:\n\n10-year service life (typical elevator):\n  Single core reliability: 99.9% (very reliable)\n  Dual core reliability: 99.99% (more reliable by order of magnitude)\n  \n  Practical example (1,000 installations):\n    Single core: ~1 catastrophic failure expected\n    Dual core: <0.1 catastrophic failures expected\n  \n  Cost of failure:\n    Single catastrophic failure: $50,000\u2013100,000 (elevator replacement cable, downtime)\n    Dual cores prevent this: ROI clear\n\nEarthquake\/shock loading scenario:\n\nSeismic event (area with earthquake risk):\n  Sudden jerk on cable: Shock loading (high stress, brief)\n  Single core risk: Brittle fracture possible if stress exceeds ultimate\n  Dual core benefit: Load distributes, single fracture less likely\n  Safety: Dual cores provide margin against seismic shock\n        <\/div>\n\n        <h2 id=\"section-5\">5.

Risk: If machine room exceeds 90\u00b0C ambient, marginal safety LIFT-2S UL approach: &#8220;Design for mechanical redundancy + moderate conditions&#8221; &#8211; Accept standard 90\u00b0C temperature (sufficient for most installations) &#8211; Dual mechanical cores (if one damaged\/broken, other maintains function) &#8211; Better long-term reliability (don&#8217;t rely on control circuit for mechanical failure) &#8211; Assumes: Some machines rooms may exceed 80\u00b0C, but not 90\u00b0C &#8211; Benefit: Fail-safe mechanical backup (independent of electrical system) Application selection: Choose LIFT-1S UL if: \u2713 Machine room is non-air-conditioned, exposed to sun \u2713 Building has no climate control in elevator shaft \u2713 Located in tropical climate with extreme heat \u2713 Temperature analysis shows >85\u00b0C sustained possible \u2713 Willing to pay premium for 105\u00b0C rating Choose LIFT-2S UL if: \u2713 Standard commercial elevator in air-conditioned building \u2713 Mechanical redundancy more important than temperature headroom \u2713 Budget-conscious (LIFT-2S UL lower cost than LIFT-1S UL) \u2713 Temperature typically","protected":false},"author":1,"featured_media":12108,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"left","csco_page_header_type":"title","csco_page_load_nextpost":"","footnotes":""},"categories":[165,35,464],"tags":[58968,52864,58970,52879,51947,58972,58978,35428,507,58959,58969,18553,56573,58974,58980,380,58979,4491,58983,58967,58982,58981,58985,58977,57358,58966,58971,58975,52723,58976,58953,57625,58984,58962,58973],"class_list":["post-12107","post","type-post","status-publish","format-standard","has-post-thumbnail","category-drag-chain-cable","category-festoon-cable","category-flexible-cables-with-high-bending-life-and-fatigue-resistance","tag-25c-to-90c","tag-12g1-5","tag-16g1-5","tag-24g1-5","tag-600v","tag-8g1-5","tag-90c-insulation","tag-90c-temperature-rating","tag-abrasion-resistance","tag-black-nylon-covering","tag-class-m-extra-fine-stranding","tag-csa-awm","tag-csa-certified","tag-dual-galvanized-steel-cores","tag-dual-core-elevator-cable","tag-elevator-cable","tag-extra-fine-stranded-copper","tag-feichun-cable","tag-fretting-corrosion-prevention","tag-lift-2s-ul","tag-mechanical-backup","tag-mechanical-redundancy","tag-mylar-tape-wrapping","tag-north-american-elevator-cable","tag-notch-resistance","tag-pendant-systems","tag-pvc-filler","tag-pvc-nylon-hybrid-insulation","tag-ral-1021","tag-safety-identification","tag-ul-2562","tag-ul-certified","tag-ul-mtw","tag-vw-1-flame-rating","tag-yellow-ral-1021-outer-sheath","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12107","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/comments?post=12107"}],"version-history":[{"count":2,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12107\/revisions"}],"predecessor-version":[{"id":12114,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/12107\/revisions\/12114"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/12108"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=12107"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=12107"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=12107"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
