飞纯 XLPE绝缘 6.35/11KV 与 12.7/22KV：固定敷设高压馈电电缆技术解析

XLPE绝缘高压馈电电缆是什么？该系列是用于固定条件下的高压馈电电缆，电压等级包括 6.35/11KV 和 12.7/22KV。电缆采用绞合裸铜动力导体、XLPE绝缘、逐芯铜线屏蔽、PVC内护套、镀锌钢丝铠装和PVC外护套，形成适合固定线路供电的高压铠装电缆结构。

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
