The cable tray shall be made of metal. The cable tray is mainly composed of steel and tray. According to the use direction of fire-proof cable tray, the thickness is 3mm and 25mm respectively. Next, Shandong cable tray manufacturers will talk about the conditions for determining the fire-proof cable tray.
It is required that the section of the bridge, the fire-proof cable bridge and the network data form a closed or semi closed structure. The surface of the bridge shall be coated with appropriate paint, and its overall fire resistance performance shall meet the requirements of relevant specifications. Cable trays shall not be used in places with high engineering requirements.
The cable tray is a corrosion-resistant tray. The strength, rigidity and stability of the steel cable tray with a span of more than 6m and the cable tray with a span of more than 2m or a bearing requirement greater than the load level D shall be checked or tested according to the engineering conditions.
When selecting the product type, the cable tray factory shall master its own product type and data, i.e. structural characteristics and data. Products made of different materials have different prices. If the selected product is confused with the structure type, it will become the job of the job. The Engineer shall also deal with the environmental characteristics of the project, the structural characteristics of the product and the product model.
When selecting cable tray materials, we must understand that the products we need have better water resistance or corrosion resistance. If you choose FRP products, it is characterized by light weight and not easy to burn. Its service life is long, generally 20 years.
The resolution of filling rate of fireproof cable tray is also one of our choices. The demand depends on the height of the product and the width of the step, which cannot meet the demand of product filling. Generally, the control cable requires a filling rate of 50% - 70%.
But in terms of price, it is three times that of steel products. In the construction process, workers are easy to use and assembly is sensitive. It will be applicable to the chemical plant industry.
