This will involve purchasing additional hangers and wasting more time drilling holes in the ceiling. Long-Span Trays: These are highly powerful, and they reach a distance. Standard lengths of 3 to 6 meters Rung spacing of 150, 225, 300, and 450 millimeters Ladder cable tray is generally used in applications with intermediate to long support spans, 3meters to 6 meters. Several factors influence the maximum span length of a cable tray: 1. Cable Weight Heavier cables require shorter spans to prevent structural strain. When installing two cable trays in parallel at the same height, the distance between them should be no less than 0. In cases where a tray is not strong enough to hold the mass of the weight it contains, it. National Electrical Code (NEC) specifies the capacities of cables rated at 2000 volts or less in cable trays.
