Distribution boxes, cable tray vertical shaft, trough cable tray, tray cable tray, Ladder type cable tray, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable tray FRP cable tray how to choose, Stainless steel cable tray, aluminum cable tray, room alignment tray, FRP cable tray, CSP alloy plastic cable tray, cable tray installation - Henan InfoQuick bridge voltage electrical equipment Co. branch configuration of a hanger, indoor branch, hanging short span generally take 1.5-3m. Outdoors column generally taken in stride 6m. 2, support and hanger configuration of the non-linear segment on the following principles. When the bridge width 300mm FRP cable tray, in addition to meeting the following conditions, in the middle of the non-linear segment should also support the creation of a hanger. 3, when the bridge multi-center distance between layers is set to 200,250,300,350 mm. 4, the bridge should remain straight segment joints every 50m 20-30mm (metal bridge). Distribution boxes, cable tray vertical shaft, trough cable tray, tray cable tray, Ladder type cable tray, DJ-type large span cable tray, CABLOFIL mesh cable tray, hot dip galvanized cable trays, stainless steel cable tray, aluminum alloy cable tray FRP cable tray on the alignment bridge in InfoQuick bridge, engine room, FRP cable tray, CSP alloy plastic cable tray, cable tray installation - Henan InfoQuick bridge voltage electrical equipment Co., Ltd. due to environmental temperature changes, steel cable tray will thermal expansion and contraction phenomenon. Outdoor bridge affected by temperature environment such as the maximum temperature is 40 ℃, the lowest temperature of -20 ℃ FRP cable tray customized telephone, cable tray, the maximum amount of shrinkage calculated by the following formula: Δt = 11.2 × 10-6 × 60deg ( degrees) × 1000mm conclude: When the temperature difference is 60 ℃, Δι = 0.672mm / m difference in temperature is 50 ℃, Δι = 0.560mm / m difference in temperature is 40 ℃, Δι = 0.448mm / m engineering design straight segment cable tray should consider expansion joints, expansion joints spacing recommendations given by the following check: When the temperature difference is 40 ℃ to 50m; to 40m when the temperature difference is 50 ℃; to 40m when the temperature difference at 60 ℃; grounded InfoQuick bridge according to relevant provisions of the standard, galvanized cable tray be well grounded.
