In the electrical wiring of large buildings, a cable trays system is commonly used in order to support isolated electrical cables utilized for communication, control, and lighting. Cable trays are manufactured with both indoor and outdoor applications. They are designed to accommodate different electrical loads and provide protection against corrosion. Cables are classified according to the cable diameter, the location where they will be installed, the amount of wire that can be placed in each slot, and the number of insulation layers. The most common type is the electrical cable rack.
Electrical cable trays are constructed with an in-built locking mechanism that ensures the protection of electrical cables. Some types of cable trays have additional features such as temperature control, noise control, tamper resistance, and safety. Some cable trays are equipped with a removable bottom panel that can be removed to access cables. For larger cables, multiple cable trays can be installed. Ramps are used to install cable trays. The cable rails or ramps are made from either steel or concrete and they function by providing firm and permanent support for cables. They are normally installed on raised floors. The use of Cable Rails helps in the easy installation of cable trays and can minimize labor requirements.
Fiber-optic cables are another type of wiring that are often installed in cable trays. Fiber-optic cables are much smaller than electrical cables and are therefore easier to install. However, they can lead to serious signal interference in offices or homes, if not installed properly. Most importantly, cable trays help in saving cost and provide system performance. In most offices and homes, cable trays help in reducing cables costs and provide better system performance and enhanced system performance. Cable trays may also prevent the cables to become redundant, which is a very important factor in systems and offices where multiple networks are interconnected. Cable trays help in enhancing the system performance and can reduce the cost of cable systems.
