[Chai Jin cable tray to recommend the star product - bridge] from the trough, tray or stepped straight segments, elbow, tee, cross components and supporting arm (arm bracket), hanger and the like have The full name of the rigid structure of the support system of close contact with the cable (hereinafter referred to as the bridge). Bay Bridge has been continuously on the market is the recognition and acceptance of the localization industry's efforts cable tray, made of high quality cold-rolled steel products, received extensive attention of high quality cold-rolled steel products, surface craft cold galvanized, hot dip galvanized, electrostatic spraying, fire retardant paint, paint. [Chai Jin cable tray to recommend the star product - the bridge] in accordance with the relevant provisions of the grounding specifications, galvanized cable tray good grounding. (1) Each of galvanized cable tray plate bolts directly contact resistance should be less than 0.005Ω, this time as a cable tray grounding line (dusting cable trays are not suitable for grounding lines) galvanized steel bridge manufacturer, the resistance of each cable tray value can be calculated as follows: r = ρ · L / S where: ρ = 15 × 10Ω-6 / cm (20 ℃); L = length calculated according to 100mm; S = cross-sectional area cm2. [Chai Jin cable tray to recommend the star product - Bridge] cable tray cable tray load load into load, dynamic load and the additional load. Static load refers to the laying of cables in the cable tray types, root number, diameter of each weight / unit length of galvanized tray, cable laying by different routes, respectively Lists Statistics. Dynamic load is the weight of the cable tray installation and maintenance during construction maintenance personnel. For lightweight galvanized cable tray bridge models, generally do not consider dynamic load galvanized bridge trough, which is not allowed on the bridge station (line), and if they need to be considered to stand on, they should be appropriately reduced span. Additional load refers only outdoor ice and snow loads, wind and electromagnetic force is formed, it is with the nature of the installation site of the region's natural weather conditions and charged body concerned, the design should be calculated based on various conditions. Galvanized bridge ground, galvanized tray preferred Chai Jin cable bridge, the bridge provided by the Tianjin Xianyang Chai Jin galvanized cable tray Limited. Chai Jin Tianjin cable bridge Limited (www.tjcjdlqj.com) is Tianjin, metal building materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chai Jin leader in cable tray with the staff warmly welcome all inquiries negotiations to create Chai Jin cable tray a better future.
