< p="">    Polymer cable trays are organically blended with special polymer materials and other characteristic plastic additives according to international standards, so that they have engineering polymer materials that meet various application sites. The product has flame retardant, acid and alkali resistant oxidation and good physical and chemical properties, and is the first choice in future construction engineering applications. The polymer cable tray is a common cable laying method in the electrical construction of today's construction projects. The installation of the cable tray is provided with the following steps:
    1. Measurement positioning: firstly identify the bridge by the elastic method The installation position determines the fixed position of the bracket.
    2, bracket production and installation: according to the actual measurement size design, production bracket.
    3. Bridge installation: Coordinate with each major before installation to avoid conflicts with various equipment. The gap between the bridges must meet the design requirements during installation to ensure that the bridges of one system can be integrated. The installed bridge frame should have the characteristics of neat appearance, uniform distance and firm connection, and it is required to achieve the horizontal deviation within the same horizontal plane not exceeding 5mm/m and the straightness deviation not exceeding 5mm/m. 4. Grounding treatment: Bridges are connected by a soft copper wire of not less than 4mm2, and then the bridge is connected to the grounding wire to form an electrical path. At the same time, the overall structure of the bridge and the grounding trunk There should be no less than two connections.
    The raw material composition of polymer materials: polyethylene, ABS, aluminum hydroxide, polyvinyl chloride, flame retardant, polyurethane, polytetrafluoroethylene, etc.
    Shandong Oukai Polymer Materials Co., Ltd. polymer cable bridge is made of polymer material PVC and ABS polyphenylene oxide and other organic materials, the annual production capacity reaches 3 million meters. Its products are widely used in steel, metallurgy, petroleum, chemical, machinery, electric power, transportation, civil construction, and its products are used in Fengnan Iron and Steel, Shandong Iron and Steel, Guangxi Shenglong Iron and Steel, China Aluminum, Fujian Ningde Copper, etc. In industrial projects, the products sell well in more than 20 provinces, municipalities and autonomous regions, and the sales network covers all parts of the country, and the market is in good condition.
