Detailed Product Description: | [Chai Jin cable tray to recommend the star product - Bridge] company to provide customers with accurate and timely service, quality products, competitive prices, and we now look to the future will be based on trough cable tray, the pioneering and innovative, with the times enter. Some are passive electrical (optical) cable (such as data cables, video coaxial cable, etc.) Cascade cable bridge, therefore, when the arrangement layout and routing in the design, should be distinguished, not only should be compliant requirements, but also consider the wiring security, scalability, economy and aesthetics, ease of maintenance, cable tray as the bearer of various cabling carrier belonging wiring required, the same should be implemented following the above principles. [Chai Jin cable tray to recommend the star product - the bridge] bridge within its control cable does not exceed the total cross section s total cross section of cable tray s. 40% of the principle. Total cross section s control cable is: where: s1, s2, s3 ...... for various control cable bridge in cross-sectional area (including the sheath section) units of mm, d3 ...... within the outer diameter of the cable tray various control The unit is mm; nnn ...... the number of these same types of specifications of the cable. Corresponding control cable tray width b: where h is the height of tray cable tray cable tray, in mm. When the cable tray installation indoors, in order to ensure the bridge straight beautiful, neat line, it is generally horizontal load deformation should be controlled within 4.0mm. [Chai Jin cable tray to recommend the star product - the bridge] be well grounded according to the specifications of the relevant provisions of the grounding cable trays, galvanized cable tray. (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 line), the value of each resistor type cable tray press calculated: r = ρ · L / S where: ρ = 15 × 10Ω-6 / cm (20 ℃); L = length calculated according to 100mm; S = cross-sectional area cm2. Standard cable tray | Chai Jin cable tray (certified) | Zhejiang cable tray cable tray provided by the Tianjin Chai Jin 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.
