Demand for Cable Trays to Increase with Significant Growth in Construction and Sector Rapid Urbanization
In electrical wiring of modern buildings, a cable tray is used in conjunction with insulation to support insulated electric cables used primarily for communication, control, and distribution. They are often used in industries where high loads have to be supported, such as factories. There are two types of cable trays: installed and portable. The installed version can be utilized in any location provided it is attached to a power point or other power generating facility. Portable ones can be utilized in any location that has an available power source.
Various industries
require cable trays with different sizes and shapes. There are many factors to
consider in buying them including the size of the cable, its function, ease of
installation, and the capacity of the wires to be supported. The cable length
in turn is determined by the weight and the cross-sectional area of the cables.
All these factors need to be considered before deciding upon the right size and
the right shape of the cable tray.
The Class A cable trays
are the most commonly permitted form in which any number of insulation cables
can be installed. There are generally three types of cable trays used in Class
A applications: panel, plunger, and conductor. The panel type facilitates easy
cable installation over metal surfaces, such as stainless steel and certain
types of metals. The plunger type facilitates the placement of large numbers of
cables in a constrained space, such as on the floor of factory floors.
The Class B cable trays
are the second most commonly permitted type. The advantages they provide are
higher safety and better flexibility for the installation of long and
complicated cable systems, superior to Class A cable trays, and they are very
cost effective and energy efficient. The Class C cable trays are the least
commonly permitted form of trays and are mainly used in factory assembly lines.
They can support only a single wire or cable per strip, and their installation
requires an expert, and skilled installer.
The demand for cable
trays is expected to increase with significant growth in the construction
sector and rapid urbanization. For instance, according to Hauptverband der
Deutschen Bauindustrie (Main Association of the German Construction Industry)
and Zentralverband Deutsches Baugewerbe (Central Association of the German
Building Industry), Germany’s construction industry is expected to witness
increase in revenue by 8.5% to reach US$ 145 billion in 2020, following an
estimated increase of 11% in 2019.
