Long-span cable trays in North Macedonia

Long-span cable trays in North Macedonia can be installed with support intervals of 14–20 feet, using local suppliers like Jeetmull Jaichandlall and Cable House for high-quality materials.Technical ConsiderationsFor long-span cable tray installations, the support span is critical. Typical long-span trays are supported at 14 to 20-foot intervals, with 20 feet being the most common. Extra-long spans may exceed 20 feet, especially for outdoor installations crossing roads or large open areas. The distance between supports affects tray strength exponentially, so the tray system must be designed according to the chosen support span. Splice plates should be placed carefully, ideally with only one plate per support span, to maintain structural integrity and electrical grounding . Cable trays are available in various materials such as steel or aluminum, offering durability, load-bearing capacity, and resistance to wear and environmental conditions. Open designs allow for ventilation and heat dissipation, which is particularly important for high-density cable runs .Local Suppliers in North MacedoniaSeveral reputable suppliers provide cable trays suitable for long-span installations:Jeetmull Jaichandlall (P) Ltd.: Offers a wide range of cable trays in different sizes, shapes, and materials, with modern manufacturing facilities and adherence to industry standards .Cable House: Supplies durable and reliable cable trays, manufactured with advanced technology and graded raw materials, suitable for industrial and commercial applications .
