Using cable ladders is very economical on all costs

Using cable ladders saves many different costs, please see the below article for details

Depending on the diagram of circuits and the density of electric wire systems, installing cable ladders for transmission wire systems can make a decrease on the total cost (materials + labors) by 60% compared to the installation cost of an equivalent cable conduit system. Besides, using cable trays for electric wire systems is economical on the costs of design, material purchase, installation and maintaine.

Design cost saving

There are few projects which can accurately identified at the beginning of design. The project will keep going through the process of design, implementation and ensure about safe requirements of electrical systems. Changes and necessary supplements will be implemented to meet all the demands of the projects through the process of design and sometimes at the beginning of construction stage. For the projects which cannot be identified 100% accurately before starting to design, cost and time for implementing changes in the stages of designing will be significant savings when using a cable tray system for wires compared to an equivalent duct system.

It only takes some minutes to change the design of the width of cable trays in order to be able add a significant amount of cables with lower addition cost. With cable conduit systems, any changes in any requirements on the capability of increasing transimission wires  in the electric wire systems at the final stage of the design is costly and time consuming. Cable trays have a special feature is allowing the cables to enter or exit the cable trays at any points along the cable tray systems, but for other wiring cable systems, it is very difficult.

Using cable trays for wiring will simplify the overall wiring design. The design of the cable conduit system can be very complex due to the cable pull boxes, cable junction boxes and the supports for the cable conduit system.

Material cost saving

The necessary components for installing a system of much smaller cable trays than a cable conduit system. Less different components mean more cost savings to identify, order, receive, store and distribute them during the process of design, material purchase and installation.

In addition, the cost of cable trays, necessary accessories, can save up to 80 percent compared to the cost of cable conduits, supporting supports, cable connecting boxes, cable pulling boxes and other accessories.

Installation cost saving

Installation work will save more working time and cost than the equivalent cable conduit system. The experience requirements of electrician install a cable tray may also be lower than that of a cable duct system such as the ability to bend a cable duct.

Cable trays can be installed more quickly than cable conduits. Cable tray systems which are completed in a shorter period of time will have less conflict of working space with the installating process of other components in the building.

The components which are used for installing the cable tray system are fewer than the cable conduits so arrangement and installation are less expensive and complex.

Wiring in the cable tray systems are also simpler and requires less labor time than cable conduit systems. Wire routing in the cable duct systems takes time and requires thorough work.

Maintainance Cost Saving

The damage of Insulation shells of eletric wires rarely happens. While electric wires in the cable conduit system could be broken in the process of pulling into the conduits. This could be caused by too strong pulling force or the size of the conduits does not fit, which makes the conduits stuck in the conduits during installation and will lead to the damage of insulating shells of conductors.

The cables can go in and out of the cable trays at any points along the cable tray systems, allowing necessary wiring addition in the future with very small cost. This is a feature that only cable ladders have

Moisture is a major cause of the failure of  electrical equipment and materials. Day and night temperatures fluctuate, resulting in moisture in the air that can accumulate in the cable ducts. Over time, this humidity can accelerate corrosion of some metal components of the electrical equipment and damage the insulating shell of the conductors. Sealing of the duct system also does not increase the effectiveness of preventing moisture movement. The cable tray systems are capable of limiting the accumulation of moisture inside, thereby reducing maintaince cost for the cabling system and electrical equipment in the future.

The design and installation of cable tray or ladder systems for conductors can also reduce damage in the event of a fire, and at the same time, repairs and replacements are easier and less costly than cable conduit systems

Installing the cable trays for the building's wiring systems can save significant cost compared to cable duct systems. They are more convenient, reliable and more secure than cable ducts systems.
