What kinds of materials are Cable Ladders made of?

There are many kinds of cable ladders; each kind is made of different materials in order to serve for different requests. The differences among kinds of cable ladders are in the quality of products and decided by the materials being used to make products. Below article will give you the detail information of popular materials being used to make cable ladders.

Cable Ladders are mechanical products used mostly in running the line of electrical wires. Nowadays, cable ladders play an important role in industrial and commercial construction works. They provide solutions which are fast, saving, flexible and effective for wiring in buildings.

Cable ladders can support all of electrical wire systems including:

- Conductors with high voltage

- Cables distributing electricity

- Conductors controlling sensitiveness

- Telecommunication cables

- Optical Cables

Almost kinds of cable ladders are made of anticorrosive metal (low carbon steel, stainless steel or aluminum alloy) or made of a type of metal which are covered by anticorrosive layer (zinc or epoxy resins)

Choices for any particular installation cases depend on installation environment (corrosion and electrical matters) and investment cost.

Aluminum

Cable Ladders which are made of aluminum often used because of the high proportion of strength-to-weight, endurable with corrosive environment and easy installation. Aluminum cable ladders have some advantages: light weight (only equivalent to 50% of steel cable ladders) and low maintenance cost. Because aluminum cable ladders are not electromagnetic; the power consumption can be reduced to a minimum level. Cable ladders are made of 6063 alloy used for maritime applications. Alloys which contain silicon and magnesium at the appropriate rate to form magnesium silicate are capable of good heat treatment. In some cases, magnesium and silicon has good appearance and good structural properties and excellent corrosion - resistance.

Aluminum cable ladders is able to resistant to corrosion both due to weather and other corrosive impacts of the air which is caused by the formation of sustainable alumina layer on the surface of aluminum. Durability with the chemistry of aluminum in the actual environment should be checked before installation.

Steel

Cable ladders are made of steel which has typical structure using a continuous process rolling and forming. Formation and extrusions increases mechanical reliability.

The main benefits of cable ladders are high durability and low cost. Their disadvantages are high weight, low electrical conductivity and low capability of corrosion – resistance. The rate of corrosion changes depending on environmental elements, coating or protective coating used and the composition of the steel.

Stainless steel

Stainless steel has high elastic limit and high crawling strength even in high temperature environment surroundings.

Electrical cable ladders made of stainless steel are rolled to form from AISI stainless steel, type 316.

Stainless steel has high durability with organic chemicals and inorganic chemicals even at high temperatures. With higher chromium and nickel and carbon reduction will increase the ability of corrosion- resistance and welding work becomes easier. Type 316 includes molybdenum increasing reliability with high temperature and enhanced the capability of corrosion- resistance, especially is chloride and sulfuric acid.
