SUPERIOR TRAY: Cost Effective Custom Made Cable Tray System

Superior Cable Tray is a CSA and UL certified Cable Tray/Cable Support System. Medico Fabrication Inc. manufactures custom designed top quality heavy duty cable tray systems which are reliable, robust and cost effective. They are excellent in quality, performance and durability.

Superior Tray manufactures six (6) types of Cable Tray Systems; namely, Ladder Tray, Hefty Tray, Instrument Channel, Center Hung, Basket Tray and Special Trays.

1. Ladder Tray (Flanges In)

This cable tray with flanges in is best for supporting instrumentation, power and control cables of various diameters. It is particularly used by power plants, pulp and paper mills, petrochemical plants and industrial construction that require reliability and may have limited space available. These trays are manufactured from aluminum, mill galvanized steel, HDGAF steel or stainless steel based on project needs. Powder coat finishes are also available.

2. Hefty Tray (Flanges Out)

This cable tray with flanges out is designed for multiple large cables and is frequently installed at paper mills, power plants and other industrial plants. The design has the rungs welded to the outside of the rails to further enhance its structural integrity while reducing side rail rotation. These trays are manufactured either from aluminum, mill galvanized steel, HDGAF steel or stainless steel based on project requirements. Powder coat finishes are also available.

3. Instrument Channel

Instrument Channel is a one-piece channel section, typically 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.

4. Center Hung

This cable tray has been designed to simplify the support and routing of power and telecom/teledata cabling. Reduced support requirements make installation easier, providing substantial savings on both cost and installation time. On a center hung tray, cables may run on both sides.

5. Basket Tray

This is a wire mesh style cable tray designed for the data and communications cabling industry, provides the additional support that sensitive cables and fiber optics require to prevent damage by using basket tray's welded mesh.

6. Special Tray

The design and manufacturing team of Superior Tray have developed several custom designed unique trays for our customers' specific project needs. These special trays have been classified into five categories:

a) EMI Tray or EMI Enclosure System

b) EAM Tray (Integrated Wireway System)

c) AI 7 Tray

d) Telco Tray

e) Universal Tray

SUPERIOR CABLE TRAY BENEFITS

The benefits of Superior Cable Tray Systems vary depending on the type of cable tray required.

The Ladder Tray is used in approximately 75% of the cable tray wiring system installations, due to its many desirable features:

- A Ladder Tray without covers permits the maximum free flow of air across the cables. This allows the heat produced in the power cable's conductor to effectively dissipate. Under such conditions, the conductor insulation in the cables of a properly designed cable tray system will not exceed its maximum operating temperature. The cables will not prematurely deteriorate due to excessive operating temperatures.

- The rungs of the Ladder Tray provide convenient anchors to tie down the cables in the non-horizontal cable tray runs or where the positions of the cable tray must be maintained in the horizontal cable tray runs. This is necessary for single conductor cable installations, because under fault conditions (short circuit), the magnetic forces produced by the fault current will move the single conductor cables from the cable tray if they are not securely anchored to the tray.

- Power cables may exit or enter the ladder trays through the top or the bottom of the cable tray. Where the power cables enter or exit conduit, the conduit to cable tray clamps may be installed upright or inverted to terminate conduits on the top or bottom of the cable tray side rail.

- Moisture cannot accumulate in ladder trays.

- If cable trays are being installed where working space is a problem, hand access through the cable tray bottom may help to facilitate the installation of small diameter cables such as: control instrumentation, signal, etc.

Hefty Tray benefits are similar to ladder tray with the major difference is the tray's outward flanges that is required at many power cable installation project for external rigid attachment. It is most suitable for multiple large cables installation.

Center Hung Tray is used to support and route power and telecom/teledata cables. The simple design saves time and has less support requirements. This saves 50% in material cost compared to standard cable trays.

On the other hand, the basket tray is designed to provide additional support to prevent damage of the sensitive and fiber optic cables for the data and communications cabling industry.
