main power circuit to individual apartments

12 Min Read
BASKET SPREADER 740 (YSLTOE) is engineered specifically for hoisting and control applications where mechanical flexibility and electrical reliability must coexist in marine environments. Unlike load-bearing structural cables (which prioritize tensile strength), control cables emphasize: Conductor flexibility – Repeated bending over pulleys without mechanical fatigue Insulation integrity – Voltage breakdown resistance under salt-fog corrosion Mechanical damping – Rope-like flexibility to drape naturally in spreader bar frames Environmental barrier – Outer sheath blocks salt, moisture, and UV penetration Core Design Elements: Component Material Specification Function Port Environment Benefit Conductor Flexible red copper Class 6 (IEC 60228) Carries 300/500V power; enables bending flexibility High purity copper resists galvanic corrosion Insulation PVC type YI2 (IEC 60811) Electrical isolation; voltage breakdown resistance (2 kV test) PVC with marine additives prevents salt-induced tracking Central Unit Aramide yarns (Kevlar™ equivalent) Mechanical load-bearing backup; structural integrity Aramide resists moisture & salt; absorbs vibration stress Outer Sheath PUR type 11YM1 (DIN 73377) Environmental barrier; UV/ozone/moisture protection Superior salt-fog resistance; 20+ year marine lifespan

LIFT-2S (European) vs. LIFT-1S UL (North American): LIFT-2S characteristics: Voltage: 300/500V (European standard, lower voltage) Temperature: −40°C to +70°C (moderate range) Standards: VDE 0482 part 265-2-1, EN 50265-2-1, IEC 60332-1-2 Design philosophy: Safety by material redundancy (2 steel cores) Steel cores: 2× cores provide mechanical backup Conductor: Class 6 (European, ~150–200 wires per mm²) Cost: Lower (proven European manufacturing) Market: Europe, Asia-Pacific, most of world LIFT-1S UL characteristics: Voltage: 600V (North American standard, higher voltage) Temperature: −25°C to +105°C (extreme range, high-temp optimized) Standards: UL 2562, UL 62, CSA C22.2 No.210.2 Design philosophy: Safety by certification (single core + redundant control) Steel core: 1× core (sufficient with nylon covering) Conductor: Class M (UL, extra fine ~300+ wires per mm²) Cost: Higher (UL testing, certification documentation) Market: North America (USA, Canada), Mexico UL 2562 specialty certification: UL 2562 scope: Elevator and Dumbwaiter Cables Specific requirements: 1. Pendant cable design (cable hangs freely, no duct support) 2. Vertical orientation (designed for gravity-loaded suspension) 3. Repeated flex cycles (cable moves up/down frequently) 4. Safety-critical function (failure = personnel risk) Consequence: More stringent than general-purpose cables Testing includes: Bend cycle fatigue, heat aging, compression resistance Test procedures (unique to UL 2562): Bend cycle test: 1,000+ cycles at minimum bending radius Cable must pass insulation resistance after cycling Heat aging: 500+ hours at 105°C continuous Tensile strength retention minimum 70% Compression: 1,000+ hours under sustained compression Cable cross-section must not exceed 5% permanent deformation LIFT-2S (no UL 2562): Tests per VDE are less stringent on fatigue/cycling Assumes cable mostly static, not repeated flex Adequate for European elevator duty (lower speed, fewer cycles) LIFT-1S UL: All UL 2562 tests passed (proven for North American elevators) Faster cycle times, more frequent motion → more fatigue stress Extra testing ensures reliability under North American elevator duty Market requirement (regulatory): Europe/International: CE mark required (European conformity) VDE/EN/IEC standards sufficient No UL certification needed (not recognized in EU) LIFT-2S is sufficient North America (USA, Canada): UL certification mandatory for elevators UL 2562 specifically for elevator cables CSA dual certification required in Canada LIFT-2S NOT acceptable (lacks UL 2562) LIFT-1S UL mandatory Cost implication: UL certification: ~$5,000–15,000 per product per region Testing duration: 3–6 months per model Documentation: Comprehensive test reports, technical files Result: LIFT-1S UL 20–30% higher cost than equivalent European cable
