Profile: Superior Tray Systems Inc. is engaged in building standard and custom cable trays & cable bus enclosures. Our product line includes cable bus packages, modular buses, E-houses/kiosks and electrical & custom enclosures. Our cable bus enclosures are manufactured in aluminum alloy 6063-T6, stainless steel or galvanized (HDGAF) steel. The non-magnetic support blocks are designed in segments to maintain a minimum of one power cable diameter in both the horizontal and vertical planes. The enclosure parts are designed to ensure that there are no projections or sharp edges that could damage the power cable insulation or cause potential injury to personnel during its handling/transporting and installation. We manufacture six types of cable tray systems namely, ladder trays, hefty trays, instrument channels, center hung, basket trays and special trays. Ladder tray with flanges in, is best for supporting instrumentation, power and control cables of various diameters. It is particularly used by power plants, pulp & paper mills, petrochemical plants and in industrial construction. Instrument channel is a one-piece channel section, used to carry instrumentation, control, data communication, computer or telephone cable. The channel section comes with ventilated or solid bottom. The tray is designed to carry both single power cable and multiple circuit cables.
