Why Specify Snap Track Cable Tray

Snap Track was developed in response to repeated requests for a complete industrial cable tray system designed for the limited width requirements of instrumentation data cable. Snap Track has been designed to provide the ease of installation and the economy of wire basket tray while retaining the stability and inherently superior cable protection of traditional raceway. Our philosophy is simple – the purpose of a cable tray system is to “Support and Protect the Cable.”

During the design process we consulted with numerous leading instrument manufacturers, engineers, integrators, contractors, and network cable providers

Techline – Snap Track now addresses all your installation requirements from ladder tray transition to the elimination of pig tails at the instrument connection, all from a

Through our extensive distribution network all Techline products are available to your jobsite without the delays and freight costs traditionally associated with instrument mounting systems. Call 1-800-395-3369 to locate the distributor nearest you!

Snap Track Systems are designed and manufactured to meet or exeed the standards and guidelines as stated in the NEMA Standard VE1-2002. Section 4.8.3 of NEMA Standard VE1-2002 states that Channel Cable Tray straight sections not exceeding 150mm (6 inches) in width and 50mm (2 inches) in depth do NOT need to be load tested in accordance with section 5.2. However, loading data is needed to insure a properly installed system. A safe working load, as outlined by IEC 61537, is the load applied when delfection equals the

working load at different span lenghts. These values were obtained by using the procedure outlined in section 5.2 in NEMA Standard VE1-2002 and IEC 61537 as a guide.

Why Aluminum Alloy 6063-T6 Tray? According to the Cable Tray Institute’s Technical Bulletin No. 13, one of the most important choices when designing a cable tray system for corrosive or outdoor

(ASTM A-123) have been used successfully for many years. However, industrial contractors and engineers are beginning to prefer aluminum over galvanized

to have numerous advantages in design, installation, delivery, performance, and total cost over the lifetime of the installation.

Aluminum cable tray has a superior strength-to-weight ratio versus hot-dip galvanized cable tray. This means less weight that the contractor has to carry around a plant and can make a difference in the number of workers required for aninstallation. Aluminum is also superior to hot-dip galvanized in the aspect of when

galvanizing. Consequently, when you cold galvanize a piece of bare metal you have not restored the full strength and protection of the original galvanizing. Conversely, Aluminum Alloy 6063-T6 has superior corrosion resistance in many chemical environments compared to HDG, and is sometimes referred to as marine grade aluminum. Aluminum can be cut or scratched and still retain its corrosion resistance without the need of a protective coating. When aluminum 6063-T6 tray is used with stainless steel hardware, the system can perform continually, with little to no degradation over time.

The ability to extrude aluminum is another reason 6063-T6 is more preferred. By extruding our channel Techline Manufacturing has been able to obtain

It is for these reasons that Techline Manufacturing is pleased to offer to you a complete cable tray system that is manufactured of Extruded Aluminum Alloy 6063-T6.

Thermal Expansion

It is important that thermal contraction and expansion be considered when installing cable tray systems. The length of the straight cable tray run and the temperature differential govern the number of expansion splice plates required.

Temperature Differential Maximum Distance C (F) M (Feet) 14 (25) 79 (260) 28 (50) 40 (130) 42 (75) 27 (87) 56 (100) 20 (65) 70 (125) 16 (52) 83 (150) 13 (43)

* The temperature differential is the difference in the temperature between the hottest and coldest days of the year.

The cable tray should be anchored with hold down clamps at the support nearest to its midpoint between expansion splice plates and secured by expansion guides at all other support locations. The cable tray should be permitted longitudinal movement in both

Note: All Snap Track splices are provided with (4) 1 ¼” X 0.312” slots and are designed for use as expansion splices. The 1 ¼” slot also eliminates the need for gap calculations based on temperature differentials. See fasteners for appropriate installation hardware. Bonding jumpers are required at each expansion joint. * See accessories Section 4.33 for expansion guides & Section 7.56 for Hold Down clamps.

When installed with power cable exceeding 100 ampere each cable should be grounded to thetray or a separate EGC should be installed in or on Snap Track tray and should be bonded tothe tray with a grounding clamp. One ground clamp should be installed on the side rail of eachsection of cable tray. A separate EGC and ground clamps or bonding jumper should also beinstalled at any point that the cable tray is not mechanically continuous.

A bare copper EGC should not be used with Snap Track aluminum tray

NOTE- NEMA Article 392.6 clearly states that a cable tray system must be electrically continuous but does not have to be mechanically continuous. Gaps between sections are restricted to 1.8m (6 ft). Cables must be secured to the cable tray prior to and after the transition, and protected by guarding or location. The electrical connection between sections can be maintained with bonding jumpers or a ground wire.

Snap Track angle can be used as a guard for an EGC or other cable when used with bonding

at awkward intersections.

A separate EGC is not requiredwhen Snap Track is used inlow power applications



Installation

Grounding and BondingProperly Sized EGC or Bonding Jumpers

The Snap Track cable tray system was designed primarily as an alternative cable tray forindustrial data and communication cables outside the scope of NEC Article 250. When installed inthese applications all products offered within the Snap Track system, including bondingjumpers, maybe used and are suitable up to 100 ampere.

In power applications above 100 ampere alternative bonding jumpers and a separate EGC sizedaccording to NEC articles 250 and 392 should be installed. See Section 5.42. Either a separate EGC must beincluded in each cable and bonded to the tray or a separate individual EGC, rated for the maximum ampere of the circuit breaker, must be attached to the cable tray.

Note- When power and non-power cables are installed in the same tray the cables should beseparated with a metal barrier – see section 4.31

Bonding To Building Steel Or Earth

The cable tray system should be bonded to building steel and earth every 60’ (18m) for properground fault protection and signal grounding (“noise” prevention). When spans exceed 60’ andare not inherently bonded to building steel and earth through metallic supports an additional EGCconnecting to earth or the facility ground network should be installed.

Equipotential Ground Network

When installed correctly the Snap Track system will create an equipotential ground networkthat will transmit all fault currents to ground. Thereby providing protection of people andproperty and minimizing system “noise”.
