NON-METALLIC CABLE TRAY & STRUT SYSTEMS
WHY SPECIFY OUR CABLE TRAY?
Non-metallic Cable Tray Systems have been tested and proven in theharsh environment of the offshore oil and gas industry. Subject to thecorrosive conditions inherent in petroleum products, plus the dailypunishment of exposure to wind, weather and saltwater –Non-metallic Cable Tray has stood up!
Non-metallic Cable Tray gives you the load capacity of steel plus theinherent characteristics afforded by our Pultrusion Technology: nonconductive, non magnetic and corrosion-resistant. Although light inweight, their strength-to-weight ratio surpasses that of equivalentsteel products. Non-metallic Cable Tray will not rust, nor does it everrequire painting. Available in both polyester and vinylester resinsystems, they are manufactured to meet ASTM E-84, Class 1 FlameRating and self-extinguishing requirements of ASTM D-635.
The CSA/NEMA loadings, both listed in this brochure, are load-testedin accordance with NEMA/CSA guidelines.
Non-Metallic Cable Tray comes in two colors : Slate grey (polyester resin)and Beige (vinyl ester resin). Custom colors are available on request.
A surface veil is applied during the pultrusion process to ensure aresin-rich surface for superior corrosion resistance as well as an ultra-violet exposure barrier.

CORROSION GUIDE
The information shown in this corrosion guide is based on fullimmersion laboratory tests and data generated from resinmanufacturers. It should be noted that in some of the environmentslisted, splashes and spills may result in a more corrosive situation thanindicated due to the evaporation of water. Regular wash down isrecommended in these situations.
All data represents the best available information and is believed to becorrect. The data should not be construed as a warranty ofperformance for that product as presented in these tables. User testsshould be performed to determine suitability of service if there is anydoubt or concern. Such variables as concentration, temperature, time
of exposure and combined chemical effects of mixtures of chemicalsmake it impossible to specify the exact suitability of fiber-reinforcedplastics in all environments. Thomas & Betts will be happy to supplymaterial samples for testing. These recommendations should only beused as a guide and Thomas & Betts does not take responsibility fordesign or suitability of materials for service intended. In no event willThomas & Betts be liable for any consequential or special damages forany defective material or workmanship including, without limitation,labor charges or other expenses or damage to property resulting fromloss of materials or profits or increased expenses of operations.

TECHNICAL INFORMATION
A concentrated static load is not included in Table 1 (page 8). Some user applications may require that a given concentrated static load be imposedover and above the working load.
Such a concentrated static load represents a static weight applied on the centerline of the tray at midspan. When so specified, theconcentrated static load may be converted to an equivalent uniform load (We) in kilograms/metre (pounds/linear foot),
using the following formula, and added to the static weight of cable in the tray:
We = 2 X (concentrated static load, kg (lb.))Span length, m (ft.)
This combined load may be used to select a suitable load/span designation. If the combined load exceeds the working load shown on pages18-22, the manufacturer should be consulted.
LOADING CAPACITY
Strength properties of reinforced plastics are reduced when continuously exposed to elevated temperatures.Working loads shall be reduced based on the following:
Cable Loads The cable load is the total weight, expressed in lbs./ft., of all the cables that will be placed in the cable tray.
Snow Loads Depending on the area, snowfall could indicate an additional design load. If snowfall is a factor and the trayhas a solid cover in outdoor installations, a minimum load of 5 lbs. per square foot should be used.
Ice Loads If a cable tray system is subject to icing conditions, usually only the top surface or cover and the windwardside will be coated with any significant amount. It is generally assumed that ice weighs 57 lbs. per cubic foot.
Wind Loads All outdoor cable tray installations should factor in wind loads, especially the pressure exerted on siderailsof ladder trays. There have also been instances of strong winds lifting covers off trays, which can be minimizedwith the use of wraparound cover clamps.
EFFECT OF TEMPERATURE
NEMA Standard 8-10-1986If unusual temperature conditions exist, the manufacturer should be consulted.

3 Draw a line between the maximum and minimumpoints.
4 Plot the tray temperature at the time of installationto determine the gap setting.
It is important that thermal contraction and expansion be consideredwhen installing cable tray systems. The length of the straight cabletray runs and the temperature differential govern the number ofexpansion splice plates required (see Figure 1 below). The cable trayshould be anchored at the support nearest to its midpoint between theexpansion splice plates and secured by expansion guides at all othersupport locations (see Figure 2). The cable tray should be permittedlongitudinal movement in both directions from that fixed point.
Accurate gap setting at the time of installation is necessary for theproper operation of the expansion splice plates. The followingprocedure should assist the installer in determining the correct gap:(see Figure 3)

• Always observe common safety practices when assembling tray andfittings. Installations generally require some field cutting. Dustcreated during fabrication presents no serious health hazard, butskin irritation may be experienced by some workers.
• Operators of saws and drills should wear masks, long-sleeve shirtsor coveralls.
• Fabrication with Non-metallic Cable Tray is relatively easy andcomparable to working with wood. Ordinary hand tools may be used inmost cases.
• Avoid excessive pressure when sawing or drilling. Too much forcecan rapidly dull tools and also produce excessive heat which softensthe bonding resin in the Non-metallic Cable Tray resulting in aragged edge rather than a cleancut edge.
• Field cutting is simple and can be accomplished with a circularpower saw with an abrasive cut-off wheel (masonry type) or hacksaw (24 to 32 teeth per inch).
• Drill non-metallic as you would drill hardwood. Standard twist drillsare more than adequate.
• Any surface that has been drilled, cut, sanded or otherwise broken,must be sealed with a compatible resin.
• Carbide tipped saw blades and drill bits are recommended whencutting large quantities.
• Support the Non-metallic Cable Tray material firmly during cuttingoperations to keep material from shifting which may cause chippingat the cut edge.
• Each tray section length should be equal to or greater than thesupport span.
• When possible, the splice should be located at quarter span.
• Fittings should be supported as per NEMA VE2-2000 Section 4.4.
Installation of Thomas & Betts Non-Metallic Cable Tray should be made in accordance with the standards set by NEMA VE2-2000Publication and CSA Standards.
