Product Description
Product Overview
The Powder coated cable tray, also called firespraying cable tray, is a cable tray product that has a layer of fire-resistant coating sprayed on the surface of a common cable tray, endowing it with fire-proof and flame-retart functions. When a fire breaks out, it can prevent the spread of fire for a certain period, protect the cable lines, ensure the normal operation of relevant electrical equipment during the fire, and gain time for personnel evacuation and fire-fighting and rescue.
Working Principle
The Powder coated cable tray is mainly based on the characteristics of the fire - resistant coating. Under normal temperature, the coating formed by the fire - resistant coating plays a protective and decorative role on the cable tray. When encountering high - temperature fire, the fire - resistant coating will undergo physical and chemical changes such as expansion and carbonization, forming a thick heat - insulating layer. This heat - insulating layer can effectively block the transfer of heat to the cable tray and cables, slow down the heating rate of the cable tray and cables, reduce the risk of cable damage or combustion due to high temperature, and thus extend the normal working time of the cables during a fire.

Structural Features
Good Coating Adhesion: The fire - resistant coating is closely combined with the cable tray substrate, forming a uniform and firm coating on the surface of the cable tray, which is not easy to fall off. Whether during the installation process or long - term use, it can maintain a good adhesion state, ensuring the stability of the fire - proof performance.
Diverse Cable Tray Structures: The cable tray part of the fire - spraying cable tray usually has various structural forms such as trough - type, ladder - type, and tray - type, which can be selected according to different usage scenarios and cable laying requirements. For example, the trough - type fire - spraying cable tray has good sealing performance and is suitable for places with high requirements for cable protection and where dust and water vapor need to be prevented from entering; the ladder - type fire - spraying cable tray has good air permeability, which is convenient for cable heat dissipation and is often used in places where there are a large number of cables and good heat - dissipation conditions are required.
High Mechanical Strength: After spraying the fire - resistant coating, the cable tray still maintains high mechanical strength and can bear the weight of the cables and various external forces during the installation and use process. Different specifications and materials of the cable tray substrate can be selected according to the actual bearing requirements to ensure safe and reliable use under various working conditions.
Materials
Cable Tray Substrate Materials: Generally, metal materials such as carbon steel and stainless steel are used. The carbon steel cable tray has high strength and good economy, which makes it suitable for fire-proof requirements in general environments; the stainless steel cable tray has better corrosion resistance and is suitable for harsh environments such as humid environments and those with corrosive media.
Fire - Resistant Coatings: There are two main categories: organic fire-resistant coatings and inorganic fire-resistant coatings. Organic fire-resistant coatings have good adhesion and decorative properties and also have excellent fire-proof performance, but they may release certain harmful gases at high temperatures. Inorganic fire-resistant coatings use inorganic substances as the main film-forming materials and have the advantages of non-flammability, non-toxicity, and smokelessness, with good fire-proof and heat-insulating performance and strong durability.
Powder-coated materials can be provided in different colors, such as Grey, Silver, Black, and Yellow, offering aesthetic appeal.
