Materials used and finishing of a cable tray

 

Cable trays are those mechanical systems that offer a rigid structural system for electrical cables, raceways, and insulated conductors and are also used for electric power distribution, signal instrumentation, control, and communication. Cable tray manufacturers in Delhi offer a wide range of cable trays at affordable prices.

Cable trays are available in six basic forms and are made up of steel, aluminium, or fiber reinforced plastic (FRP).

• Ladder Type Cable Tray.
• Solid Bottom Cable Tray.
• Channel Cable Tray.
• Single Rail Cable Tray.
• Trough Cable Tray.
• Wire Mesh Cable Tray.

By providing rapid, practical, and adaptable solutions for these difficulties, Cable Trays have become an integral aspect of industrial and commercial construction. Shree Mahalaxmi is a well known cable tray manufacturers in Noida that offers varieties of cable trays at a reasonable price.

These types of cable trays can accommodate a wide range of wiring.

• Cables for power distribution
• Sensitive Control Wiring
• Wiring for telecommunication
• Cables for optical transmission

Cable tray Materials :

• The majority of cable tray systems are made up of corrosion resistant metals that are low-carbon steel, an aluminium alloy, or chrome steel.
• The choice of Fabric for selection for each installation is influenced by the installation environment as well as on its price.
• To provide mechanical protection in areas where there are a large number of power control cables . These cables are designed to provide mechanical protection as well as a proper routing path for power or control wires.

Aluminium:

• Extruded aluminium cable trays are very popular because of their high strength-to-weight ratio, superior resistance to certain corrosive conditions, and simple installation.
• They’re also lightweight and maintenance-free. As aluminium cable trays are non-magnetic, electrical losses are kept to a minimum.
• These alloys have the right amounts of silicon and magnesium to create magnesium silicate, which allows them to be heat treated.
• These magnesium silicon alloys have exceptional corrosion resistance as well as outstanding formability and structural characteristics.
• The self-healing aluminium oxide covering that shields the surface is responsible for the metal’s exceptional resilience to corrosion, including weathering.
• Before the installation process, the chemical resistance of aluminium in the application environment should be tested.

2. Steel :

• Steel cable trays are fabricated by a continuous roll-forming technique using structural grade steels. Extrusions and forming increase the mechanical strength.
• The rate of corrosion depends on several elements, including the environment, the coating or protection used, and the steel’s composition.
• By using the method of pre-galvanized, hot-dip galvanized, epoxy, and special paints the finishes and coatings can be done to improve the corrosion resistance of steel.

3. Stainless Steel :

• At high temperatures, Stainless steel offers high yield strength and high creep strength. Stainless steel is resistant to colours, organic compounds, and inorganic synthetics, higher quantities of chromium and nickel, as well as a lower carbon content.
• It also helps to improve corrosion resistance and ease welding. To make welding easier, the carbon concentration is lowered.

Finishing of Cable tray is as follows :

1.Coatings made of Galvanized steel :

• Galvanizing is the most used cable tray coating. It’s affordable and protects against a wide range of environmental toxins, and self-heals if an area is exposed to the elements due to wounds or scratches.
• Zinc is applied to steel through electrolysis, which involves immersing it in a spray of zinc salts.
• A protective coating of carbonates, hydroxides, and zinc oxides is formed to shield the zinc itself.
• Corrosion resistance is directly proportional to the thickness of the covering and the severity of the environment.
• Racks manufacturers in Delhi aim to provide excellent cable tray finishing and coating services.

2.Coatings made of Pre Galvanized steel :

• Pre-galvanized steel, also known as mill-galvanized or hot dip mill-galvanized, is created by passing steel coils through molten zinc in a steel mill.
• After that, the coils are trimmed to different sizes.
• Cuts and welds, which aren’t generally covered during manufacture, are protected by nearby zinc, which acts as a sacrificial anode.

Coatings made of Hot-Dip Galvanized:

• Following the construction and assembly of the steel cable tray, the entire tray is immersed in molten zinc, which coats all surfaces, as well as all edges, holes, and welds.

As a conclusion, above is a quick overview of cable trays and how they are manufactured. Shree Mahalaxmi is a prominent Cable tray rack manufacturers in Noida, offering high-quality goods at a competitive price.
