High-voltage systems place different priorities on tray selection compared to low-voltage or control cabling. Ventilated Tray or Cable Ladder: The Preferred Choice. The open design of ventilated trays and ladders is almost always mandated for high-voltage power. Stainless Steel Heavy Duty Cable Tray (304 & 316 Stainless Steel) Stainless steel cable tray (304 and 316 grades) provides high strength, non-corrosive cable containment and support for low and high voltage power, control and instrumentation cables. With excellent resistance to corrosive oils. Explore various cable tray types and sizes for electrical installations. Unlike conduit systems, cable trays allow cables to be laid in bundles, improving accessibility, heat. C-Channel Swage Ladder trays are prefabricated metal structures that consist of two side rails connected by individual transverse members or rungs. Ladder tray is the most common and the most economical type of tray, also providing maximum ventilation for cabling. Rungs are fastened to the side. CABSYS cable tray manufactured by MITA powered by WIBE, is specified for rail cable containment throughout Network Rail and London Underground – GRP cable tray provides extreme corrosion resistance, zero halogen properties and high strength cable support for LV (Low Voltage), MV (Medium Voltage).
