SOLID-BOTTOM CABLE TRAY Providing additional cable protection, solid-bottom cable tray is sometimes preferred to support and protect numerous small instrumentation and control cables.
Cable trays are components of support systems for power and communications cables and wires. A cable tray system supports and protects both power and
Cable tray must be capable of supporting not just the weight of the cable, but also the weight of any equipment or materials attached to the cable tray. Additionally, dynamic environmental elements
NEMA VE 1-2017 Specifies requirements for metal cable trays and associated fittings designed for use in accordance with the rules of Canadian Electrical Code, Part I and the National Electrical Code®
The cable ampacity installed in solid tray will be similar to cable installed without spacing in accordance with CEC Rule 12-1210 (3). Solid tray will carry the same type of conductors as ventilated trays.
The load capacity of the cable trays according to the support width can be read off in the diagram using load curves – here, shown as an example for a cable tray with the tray widths 100 to 600 mm.
Cable trays are not raceways, but they are treated as a structural component of a facility''s electrical system. Cable trays are a part of a planned cable management system to support, route, protect and
