INSTALLATION OF ACCESSORIES
What is a Cable Tray System? Per the National Electrical Code, a cable tray system is "a unit or
assembly of units or sections and associated fittings forming a rigid structural system used to securely
fasten or support cables and raceways." What does this mean?
• Cable trays support cable the way that roadway bridges support traffic.
• A bridge is a structure that provides safe passage for traffic across open spans.
• Cable tray is the bridge that allows for safe transport of wires across open spans.
• Therefore, think of cable tray as the structural component of a building's electrical system.
Cable Tray systems provide rigid structural support for cables in a variety of commercial and industrial
applications. The basic styles of cable tray are: Ladder, Perforated and Solid Bottom Channel Tray
Type and Wire Basket
Ladder
Ladder consists of two longitudinal side members (side rail) connected by individual traverse (rung
support) members. It is intended for use as a power cable or control cable support.
Channel Tray
Channel is a one piece support with either ventilated perforated or solid bottom sections. These
sections are used with a single power cable, multiple control, or signal circuit cables, which would
provide better electrical shielding and better insulation mechanical protection from Foreign Object
Damage (FOD) .
1. Support Span Issues are: Strength and Length : Very important to first consider the support span
as it affects the strength of the system and the length of the straight sections required..
2. Working Load Issues are: Size (Width, Loading Depth, and Strength) Cable Load
Types and numbers of cables to support-Total cable load in kg per linear meter (kg/meter), Power - is
single layer - issue width (refer to local electrical code), Low Voltage - is stacked - issue loading depth
and width (refer to affecting code)
Select a Cable Tray system that meets the working load for the support span required and a straight
section length that fits the installation. NEMA VE 2 - Straight sections equal to or larger than span.
a. Indoor Dry - Institutional, Office, Commercial, Light Industrial use Aluminum, Pre- Galvanized Steel,
Electro Galvanized Steel
b. Indoor Industrial - Automotive, Pulp and Paper, Power Plants use Aluminum, Pre-Galvanized Steel,
Possibly Hot-Dipped Galvanized After Fabrication (HDGAF)
c. Outdoor Industrial - Petrochemical, Automotive, Power Plants use Aluminum, Hot-Dipped Galvanized
After Fabrication (HDGAF)
d. Outdoor Marine - Off Shore Platforms use Aluminum, Stainless Steel.

Summary
As a guide, a span-deflection ratio of around 1/200 satisfies most owners. This ratio provides an
allowable deflection of 15 mm in a 3 meter span, 18 mm in a 3.66-meter span, and 30 mm in a 6 -
meter span under the actual loads encountered.
Aluminum Alloys
Cable tray products are most widely formed from the 6000 series alloys. Alloys in this group contain
silicon and magnesium in approximate proportions to form magnesium silicide, thus making them
II
Steel
Steel cable trays are used principally in environments which are relatively free from corrosive attack.
They are available with various types of corrosion-resistant finishes; usually hot-dip galvanized. The
main advantages of using steel in cable tray fabrication are its high strength and low cost. Its
disadvantages are increased structural weight, poor corrosion-resistance, and low electrical
conductivity.
The Matherial use for fabrication of cable ladder, cable tray system is :
Stainless Steel
Stainless steel contains at least 10 percent chromium, along with other elements to develop specific
properties. Depending on the quality of the elements present in a stainless alloy,
BETA – Tray Product , offers cable trays and accessories in both the 304 and 316 series. These
austenitic alloys are remarkable in several respects. Unlike the other two classes, they contain nickel
in quantities from 4 to 22 percent, while the percentage of carbon is kept relatively low. When
chromium is increased for improved corrosion resistance, nickel must also be increased to retain the
austenitic structure 304 stainless steel has chromium and nickel increased and carbon lowered to
reduce carbide precipitation and increase corrosion resistance. Lowering the carbon content also
makes welding easier. 316 stainless steel has molybdenum added to improve corrosion resistance
and high temperature strength. The carbon content is also lowered to improve welding performance.
Finishes
Metallic finishes
Cable trays fabricated of steel can be protected from corrosion by coating with another metal, the
most effective way and commonly use for protecting the Metallic Cable Tray is Zinc Coated also
known as Galvanizing, Zinc protects steel in two ways. First it protects the steel as a coating and
second as a sacrificial anode to repair bare areas such as cut edges, scratches, and gouges. The
corrosion protection of zinc is directly related to its thickness and the environment. This means a 0.2
mil coating will last twice as long as a 0.1 mil coating in the same environment. The Zinc coating or
galvanizing process using one of the following methods:
Our finishing process from fabrication of cable tray and ladder system is Hot Dip Galvanized, with
method with min thickness 65micron.
( Other finishing proscess such as powder painted, electro galvanized, etc by requested ).
Hot Dip Galvanized processing shall comply with standart :
- AS / NS 4680
All our fabrication finishing of cable tray and cable ladder system is HDG and provide and original
HDG certificate for the product from HDG company where the galvanizing of cable ladder are
produced.

WIRE MESH CABLE TRAY
Introducing
Wire Mesh Cable Trays
PT. Surya Cakra Mandiri manufactures trays of different designs and sizes preferred by engineers worldwide.
Wire trays are available in standard :
LOAD Kg/sqm
MODEL W H L 1,5m span 2m span
- WM-W.50-H.50-L.3000 50 50 3000 7 3
Inspite of being light weight, these trays are strong and sturdy and can be customized as per client’s
specifications.
Wire mesh cable trays are made out of steel wires of higher strength. The trays are manufactured
by welding wires and creating a net. The net is further fabricated to form a channel followed
by finishing process.
The main advantage of wire mesh cable trays is it’s cooling characteristics. The open structure of
wire mesh cable tray allows free flow of air from all sides and thus helps installed cable to stay cool.
Since it is open from all sides, it does not accumulated dust and so is easy to clean.
