The construction of cable bridge can be undertaken independently, and can also be connected to the support of various buildings and pipeline corridors. It should reflect the simple structure, beautiful appearance, flexible configuration and convenient maintenance. All components need to be galvanized. What should be paid attention to when building Jinan cable bridge?

　　为了也可以采用铝合金和玻璃纤维增强塑料电缆桥架,外观尺寸,负荷特性与钢桥基本相似,由于铝、钢重力(A1 = 2.7、铁= 7.86)的重量,铝和钢约1:3的比例,根据两种材料的市场折扣,铝合金桥造价造价比同类镀锌钢桥高1.5 ~ 2.0倍的铝合金电缆桥架美观、重量轻、安装方便等优点，近年来，铝合金桥的应用已在一些工程中得到应用。

　　In order to lose weight, aluminum alloy and glass fiber reinforced plastic cable bridge can also be used. The appearance size and load characteristics are basically similar to steel bridge. Because of the weight of aluminum and steel gravity (A1 = 2.7, iron = 7.86), the proportion of aluminum and steel is about 1:3. According to the market price discount of the two materials, the cost of aluminum alloy bridge is 1.5 ~ 2.0 times higher than that of similar galvanized steel bridge, which is beautiful and light in weight In recent years, the application of aluminum alloy bridge has been applied in some projects.

　　济南电缆桥架在施工中需要注意什么?

　　What should be paid attention to in the construction of Jinan cable bridge?

　　注意事项

　　Matters needing attention

　　1、XQJ型电缆桥架装置的负载支撑间距较大，应小于允许的负载和支撑跨距。

　　1. The load support spacing of XQJ cable tray device is large, which should be less than the allowable load and support span.

　　2、山东地区在选择电缆桥架宽度时，应留有一定的空间，以增加今后电缆桥架的使用。

　　2. In order to increase the use of cable bridge in the future, some space should be reserved when choosing the width of cable bridge in Shandong area.

　　3、当电力电缆和控制电缆较少时，可以安装同一电缆桥架，但中间要用隔板将电力电缆和控制电缆分开敷设。

　　3. When there are few power cables and control cables, the same cable tray can be installed, but the power cables and control cables shall be laid separately with partition in the middle.

　　4. 敷设电缆桥架水平时,托盘之间的连接头应设置在大约1/4的跨度尽可能和电缆运行水平应该固定每2米左右,而垂直运行的电缆应固定每1.5米左右。

　　4. When the cable tray is laid horizontally, the connector between trays shall be set at about 1 / 4 of the span and the cable operation level shall be fixed about every 2 meters, while the cable running vertically shall be fixed about every 1.5 meters.

　　5. 电缆桥架装置应可靠接地。若采用电桥作为接地主线，则每层电桥末端用16mm2的铜线(并联)与总接地主线连接，长距离电缆桥每隔30—50米接地一次。

　　5. The cable tray device shall be reliably grounded. If the bridge is used as the main grounding line, the end of each layer of bridge is connected with the main grounding line by 16mm2 copper wire (in parallel), and the long-distance cable bridge is grounded every 30-50m.

　　6日钢电缆盘电缆托盘装置除了需要屏蔽防护盖,在户外装置应该安装在上层的防护罩,防止太阳和雨,如果焊接安装,焊接在焊接厚度不得小于基材的厚度,焊接接头必须做防腐处理。

　　In addition to the shielding cover, the outdoor device shall be installed on the upper protective cover to prevent the sun and rain. If it is installed by welding, the welding thickness shall not be less than the thickness of the base material. The welding joint must be treated with anti-corrosion treatment.
