Special for cable trays and elevator shafts

Elevator shafts and cable trays require specialized cables and support systems designed for high mechanical stress, flexibility, and safety compliance.Elevator Shaft CablesCables used in elevator shafts must withstand continuous mechanical stress, including bending, tension, and vibration, often over hundreds of trips per day. They are designed with high flexural fatigue strength and can include round or flat configurations, shielded or unshielded, with properties such as halogen-free, flame-retardant, UV-resistant, cold-flexible, and oil-resistant. Some cables incorporate load-bearing elements made of steel, aramid, or natural fibers to ensure the weight is not borne by the conductive copper strands, enhancing safety and durability . Hybrid and custom cables can also be manufactured to meet specific requirements, including printing with company logos or special surface treatments .Cable Tray SystemsCable trays provide structured support and routing for electrical and communication cables. They are typically made of steel or stainless steel, with various galvanization or coating options to improve corrosion resistance . Common types include ladder trays, ventilated trays, and mesh trays, which allow for flexible routing and easy maintenance. Fittings such as horizontal/vertical bends, T-pieces, crossovers, and end closures enable changes in direction or dimension, while support elements like wall brackets, suspended supports, and center suspensions secure the trays to ceilings, walls, or floors . Accessories like covers, barrier strips, and cable protection rings enhance safety and organization.Specialized Features for Elevator ApplicationsSuper-Flex and Super-Duct® cables offer lifetime warranties for elevator and shaft applications, ensuring long-term reliability .Compensation cables like Whisper-Flex and Steadi-Flex® accommodate movement and vibration in elevator systems .High-performance Cat6 U/UTP cables are available for data and communication lines in elevator shafts, providing EMI immunity and mechanical robustness for moving environments .Support meshes and braided structures can be integrated to reinforce cables mechanically, using materials such as aramid, hemp, or sisal .Compliance and SafetyElevator cables and cable trays must comply with standards such as DIN EN 81 for elevator safety and DIN EN 61537 for cable support systems. These standards ensure that cables and trays can withstand environmental conditions, mechanical loads, and fire safety requirements . Proper installation ensures that cables are supported without overloading conductive elements, maintaining both operational safety and longevity.SummaryFor elevator shafts and cable trays, the combination of mechanically reinforced, flexible cables and robust, corrosion-resistant support systems is essential. Products like Super-Flex, Super-Duct®, and specialized Cat6 elevator cables, along with steel or stainless steel cable trays with appropriate fittings and supports, provide reliable, safe, and long-lasting solutions for both power and communication needs in vertical transport systems .
