Why Cable tray system ?

A cable tray system is used to support insulated electrical cables used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems and are commonly used for cable management in commercial and industrial construction.

  • ■ They are especially useful in situations where changes to a wiring system are anticipated, since new cables can be installed by laying them in the tray.
  • ■ Troubleshooting made easy
  • ■ Faster installation. Installing cable tray is far less labor-intensive than conduit, so you get the job done faster and get the plant back to production sooner.
  • ■ Easier maintenance. When properly installed, cable trays and cables are easier to inspect and cost less to maintain.
  • ■ Low installation cost
  • ■ Wiring system flexibility and simplicity to understand and operate.
  • ■ A solid advantage of a cable tray is that they can adjust to intricate and difficult configurations with simplicity and standard tools.

Compact design, superior performance and attractive pricing are the key strengths Digitekk Cable Trays are known for.

PRODUCT FEATURES

A number of factors must be considered when selecting the proper cable tray system and planning the installation:
  • ■ Material and Finish
  • ■ Types of Cable Tray
  • ■ Cavity size - Load depth/ tray width
  • ■ Length of straight sections
  • ■ Rung Spacing
  • ■ Cable tray support locations
  • ■ Electrical Grounding

TYPES OF CABLE TRAY

SOLID BOTTOM TYPE

With no openings within the cable bearing surface, Solid bottom cable trays completely eliminate cable sagging and offer the most protection for the cables.

PERFORATED TYPE

Best choice for smaller cables, offer some air-flow while completely eliminating cable sagging.

LADDER TYPE

Consisting of two side rails connected by individual transverse members or rungs, most common and most economical type of tray, provides maximum ventilation for cabling.

In which we provide three types of variations in material and finish
  • ■ Powder coated
  • ■ Fabricated from Galvanized Iron sheets
  • ■ Hot dip galvanized after fabrication
Sheet Metal Thickness
  • ■ 18 Gauge (1.2mm) for light loads
  • ■ 16 Gauge (1.6mm) for intermediate loads
  • ■ 14 Gauge (2.0mm) for heavy loads

appropriate finish which provides the best combination of initial cost and expected life.

When two dissimilar metals are in contact and become damp it is possible for corrosion to be induced in one of the metals. Such corrosion may progress rapidly and cause considerable damage so it is important to consider and, if necessary, take steps to eliminate this process.

Electrochemical (alternatively referred to as electrolytic or bimetallic) corrosion takes place because the two different metals each behave as electrodes and the moisture acts as the electrolyte as in a simple battery; as with any battery the resulting flow of current will cause corrosion of the anode.

The rate of corrosion depends upon the differences in electrical potential of the metals as defined by the Galvanic Series. The strength of the electrolyte, the period for which the electrolyte is present and the geometry of the connection between the dissimilar metals are all influencing factors. When corrosion occurs it is the anodic metal (which is higher in the galvanic series) which will corrode in preference to the cathodic metal (which is lower in the galvanic series).

The best way to prevent electro-chemical corrosion is to ensure that all system

In planning any cable tray installation the choice of an appropriate corrosion resistant material and finish is always a key issue at the specification stage. The correct choice has long term implications and is crucial for ensuring the longevity and the aesthetics.

Maintenance against corrosion of cable ladder and cable tray installations is generally impractical. It is vital at the specification stage that the selected finish for the equipment is capable of providing lifetime protection from corrosion within the intended environment, ideally with some margin of safety. Therefore it is important to establish the corrosive properties of an environment to ensure the right material and finish is chosen.

The following sub-sections give information on how corrosion occurs and contain supporting technical data on the standard construction materials and surface finishes.

Few metals will suffer corrosion damage in a dry, unpolluted atmosphere at a normal ambient temperature. Unfortunately such environments are exceptional and atmospheric pollutants as well as moisture is likely to be present to some degree in most situations, thus some chemical corrosion may be expected in almost all situations.

Any support installation situated in an area where higher concentrations of chemicals exist must be subject to more detailed consideration in order to select an components have the same finish e.g. all components HDG or all components stainless steel. Where this is not possible then components with a low potential difference should be used.

In addition to the contact between dissimilar metals the relative surface areas between them also has an effect. If the anodic metal has a small surface area in relation to its counterpart it will be corroded very aggressively and any sacrificial protection it provides may be short lived. If on the other hand it has a large surface area in comparison to its less reactive counterpart, some minor corrosion may take place at points of contact but the process is likely to reach equilibrium rapidly so that any further reaction is insignificant as in the following example.

Consider the example of a tray or ladder with a thick protective zinc coating over a large area connected together using stainless steel fixings each having a small surface area. The stainless steel, in contact with the galvanizing, causes only minor corrosion of the zinc because of the small area of the stainless steel fixing in comparison with the much larger surface area of the zinc coating.
