[Chai Jin cable tray to recommend the star product - 1KV and below the bridge] in neutral grounding system grounded neutral grounding powered devices connected to the system. Fitted at moving off the power when loading Xuan, prefect direction of the metal bridge cross-sectional area of ??not less than a predetermined value. 3, along the full length of the bridge lay another grounding line, Yingkou cable trays, each (including non-linear segment) bridge should be at least a little reliable connection and grounding lines. 4, the vibration place, at the junction of the ground portion of the coil should be installed. [Chai Jin cable tray to recommend the star product - the bridge] to determine the bridge's width: according to the number of spacing of laying cable, cable diameter and the cable to determine the length of cable bridge models, specifications, the supporting arm length, pillars, distance, cable tray factory, bridge width and number of layers. (4) Determine the installation: Depending on the setting conditions to determine the place of the bridge fixed way, Cascade cable bridge, suspensory, upright, sidewall, or hybrid, fittings and fasteners are generally supporting the supply of In addition, trough cable bridge, bridge structure is selected according to the respective covers off. (5) draw cable tray level, sections, local site also drawn map, list of materials. [Chai Jin cable tray to recommend the star product - bridge] Selection Procedure trays (1) to determine the width of the bridge, the number of layers, the anchor type and spacing, as well as cable distribution in the layers of trays. (2) the calculation of each cable uniformly distributed load (kN / m2), initially identified the bridge models, specifications. (3) The maximum total cable uniform load value checking bridge strength. Cable bridge specifications, Chai Jin cable tray, cable tray from the Tianjin Yingkou Chai Jin cable bridge Limited. Chai Jin Tianjin Cable Bridge Co., Ltd. (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.
