Chai Jin Tianjin Cable Bridge Co. [1], cable tray supporting the project as a cabling project, there is no specific regulatory guidance, a manufacturer specifications program lacks versatility, therefore, the design selection process should be based on various weak systems Cable seem the type, quantity and reasonable application of the selected bridge. (1) determine the direction: According to the building floor plan, combined with air-conditioning lines and electrical lines and other settings, easy maintenance, and the cable routing density to determine the best route cable trays. In the interior, as far as possible along the wall of the building, columns, beams and slabs erection, take advantage of such a comprehensive pipe gallery set up, it should be in the side or top of the parallel pipeline erection and taking down conductors and branch lines to avoid cross fire bridge price, if no other pipe racks to borrow fire bridge Which is good, since you need to set up (branch) column. 2. When combined with the power cable tray, power cables and electronic cables should each straight side of the middle separated by diaphragms. 3, weak cable in combination with other low-voltage cable bridge, should be strictly enforced select an outer shield weak system of weak cable, to avoid mutual interference. Chai Jin Tianjin Cable Bridge Co., Ltd. [] (7) cable tray should be more than 2.2 meters above the ground, the top of the bridge from the ceiling or other obstacle of not less than 0.3 meters, the bridge width should not be less than 0.1 meters, the bridge cross-section of the filling factor It should not exceed 50%. When laying cables inside vertical (8) cable tray, at the upper end of the cable and 1.5 meters per interval should be fixed on the bridge of the stent, when the level of laying cable in the first, tail, turn and every interval of 3 to 5 m fixed. (9) is provided in the ceiling, the slot cover open surface should remain vertical clearance of 80 mm, trunking cross-section utilization should not exceed 50%. (10) cloth on the trunking cables may not be binding, the cable should be straight tank, tank cable should be straight, try not to cross, the cable should not overflow trough, the cable out of the trough in the fire site How much bridge, the corner should lashing. Vertical ducts laying cables should each interval of 1.5 m is fixed to the cable bracket. (11) in the horizontal, vertical trays and vertical groove in laying cable, the cable banding response. Four pairs of wire cable bundle with 24 to 25 pairs or more main trunk cable, optical cable and other signal cables should be based on the type of cable, cable diameter, the cable core number splitting banding. Lashing spacing should be less than 1.5 meters, the deduction should be evenly spaced proper tightness. (12) laying the bridge level, support spacing is generally when 1.5-3m, vertical laying is fixed to a building isomer spacing should be less than 2m. How much fire bridge, Tangshan fire bridge, known manufacturers Chai Jin Chai Jin from the Tianjin cable bridge cable bridge Limited. Chai Jin Tianjin Cable Bridge Co., Ltd. (www.tjcjdlqj.com) strong, credible, in Tianjin metals and building materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Chai Jin cable tray and you hand into the brilliant, for a better future!
