Flat Cable Design Advantages Over Round Cables
Flat cables offer specific advantages over round cables for elevator applications, according to industry sources. Key Advantages: Space Efficiency: Flat cables require less space, allowing for more compact installations in the hoistway. Smaller Bending Radius: Flat cables can bend more tightly without damage, enabling more flexible routing. Less Susceptibility to Tangling: Flat cables are less likely to tangle during travel compared to round cables. Derulcable (Shanghai) Co., Ltd offers oil-resistant electrical cables in both round and flat configurations for elevator control applications. The flat cable features a copper wire braided shield for anti-electromagnetic interference and a special oil-resistant jacket that remains soft at -15°C.

Lisbon Glória Elevator Accident: Non-Compliant Cable Procurement Cited
The preliminary report on the Lisbon Glória elevator accident (September 2025, 16 fatalities) revealed that the cable that failed was "not certified for use in passenger transport installations" and did not comply with Carris specifications. Key Findings: Specification Error: Carris sent specifications for the Santa Justa elevator cables to suppliers for the Glória and Lavra elevators, only changing the diameter. Non-Compliant Cable: The supplied cable was not suitable to be installed with swivels at its ends and had discrepancies in steel certification standards that went undetected. On-Site Concerns Ignored: Workers noted the cable's different composition and behavior (e.g., significant lengthening requiring a 4.5-meter segment cut) but lacked the knowledge to identify the non-conformity. Maintenance Failures: Recorded maintenance actions did not correspond to tasks actually performed, and inspections recorded as completed showed evidence they were not carried out. GPIAAF recom

Traveling Cable Termination Methods and Design Considerations
Prysmian Group has published comprehensive guidelines on elevator traveling cable design, termination, and installation. Termination Methods: Integral Support Member: Required for cables exceeding 60 meters in suspended length, using a flexible steel strand wrapped around a spool and clamped back to itself. Self-Tightening Devices: Used for cables with a suspended length of less than 60 meters. Mesh grips are common for round cables, while wedge clamps are used for flat cables. Looping Around a Bar: This method is not recommended as the severe bends cause stress points that eventually lead to conductor breakage. Key Design Considerations: Cable Strength: Use of steel support members to limit strain on copper conductors. Flexibility: Achieved through highly flexible copper conductors (e.g., 0.75mm² conductor constructed of 30 strands of 0.18mm wire) and specially formulated insulating materials. Torsional Balance: Preventing cables from untwisting under load to avoid vibration a

Elevator Flat Cable Patent Features Multi-Stage Tension and Pressure-Resistant Structure
A patent (CN104616761B) describes an elevator flat cable with a multi-stage tension and pressure-resistant structure to protect conductors from external stress and enhance durability. Key Innovations: Flexible Core: Each cable core includes multiple conducting wires stranded around a flexible core with an axial through-hole. This reduces weight and provides cushioning space for deformation. Polyester Fiber Enhancement Layer: A lapping layer and polyester fiber enhancement layer protect the cable core and improve its strength. Reinforcing Cores: Two first reinforcing cores are located at both sides of the cable bundle for enhanced side protection. Multiple second reinforcing cores are positioned between adjacent cables. Tensile Strength Differentiation: The tensile strength of the first reinforcing cores is greater than that of the second reinforcing cores to protect the cable sides from tearing. The structure ensures uniform stress distribution, making the cable difficult to stre

High-Speed Elevator Traveling Cable Patent Addresses Wind and Pressure Issues
A patent (CN102855988B) describes a high-speed elevator traveling cable with an oblong cross-section designed to address challenges in tall buildings, such as wind-induced sway and pressure. Key Innovations: Oblong Cross-Section: The cross-section is substantially oblong, increasing the cable's thickness and preventing it from being rolled by guide rail wheels. Depressions for Wind Stability: Two depressions at the ends of the long axis act as "root posts" stretching the cable under vertical hoistway wind action, minimizing lateral shift. Hollow Airbags: Two hollow airbags are arranged inside the cable to increase flexibility and improve anti-pressure ability when the cable is squeezed, protecting the cable core without damage. Aramid Fiber Ropes: Multiple aramid fiber ropes are arranged in the cable to increase stretching resistance and serve as tear lines. The design uses a large-diameter circular arc cylinder at the short-axis ends to reduce the impact of horizontal hoistway a
