Design Comparison (LIFT-1S UL vs. LIFT-2S UL): LIFT-1S UL: Temperature: 105°C (highest rating) Steel cores: 1 (single mechanical support) Redundancy philosophy: Electrical backup (dual control circuits) Yellow sheath: No (black) Insulation: PVC only (100% pure) Mylar wrap: No Size example (8G1.5): ~21.5 mm OD Cost: Higher (premium 105°C formulation) Best for: High-temperature machine rooms, non-HVAC spaces LIFT-2S UL: Temperature: 90°C (moderate rating) Steel cores: 2 (dual mechanical support) Redundancy philosophy: Mechanical backup (if one core fails, other works) Yellow sheath: Yes (RAL 1021, safety identification) Insulation: PVC/Nylon hybrid (enhanced protection) Mylar wrap: Yes (additional conductor protection) Size example (8G1.5): ~22.7 mm OD (slightly larger due to dual cores) Cost: Moderate (balanced design) Best for: Standard elevator duty, mechanical redundancy required Philosophy difference: LIFT-1S UL approach: "Design the cable to never overheat" - Optimize for high temperature (105°C possible) - Single mechanical core (simpler, lighter) - Control circuit provides electrical safety backup - Assumes: Machine room temperature controlled (or naturally cool) - Risk: If machine room exceeds 90°C ambient, marginal safety LIFT-2S UL approach: "Design for mechanical redundancy + moderate conditions" - Accept standard 90°C temperature (sufficient for most installations) - Dual mechanical cores (if one damaged/broken, other maintains function) - Better long-term reliability (don't rely on control circuit for mechanical failure) - Assumes: Some machines rooms may exceed 80°C, but not 90°C - Benefit: Fail-safe mechanical backup (independent of electrical system) Application selection: Choose LIFT-1S UL if: ✓ Machine room is non-air-conditioned, exposed to sun ✓ Building has no climate control in elevator shaft ✓ Located in tropical climate with extreme heat ✓ Temperature analysis shows >85°C sustained possible ✓ Willing to pay premium for 105°C rating Choose LIFT-2S UL if: ✓ Standard commercial elevator in air-conditioned building ✓ Mechanical redundancy more important than temperature headroom ✓ Budget-conscious (LIFT-2S UL lower cost than LIFT-1S UL) ✓ Temperature typically
