With the development of society, the construction industry has developed rapidly. Electricity is essential in buildings. Therefore, the bridge industry has also been well developed and used more and more frequently in reality, which has also brought great help to people's life. However, there are still many problems to be paid attention to in the process of how to use the bridge. Next, let's learn about the use of Shandong cable bridge and the matters needing attention in use. I hope it can help you!

1.山东电缆桥架规划的人员应自己了解规格，以确保电缆占用的体积符合要求，一般百分之40更好。尽量不要超过常规密度，以免加速电缆绝缘老化，否则需求会增加电缆和增加投资。

1. Shandong cable tray planning personnel shall understand the specifications themselves to ensure that the volume occupied by the cable meets the requirements, generally 40% is better. Try not to exceed the conventional density to avoid accelerating the aging of cable insulation, otherwise the demand will increase the cable and increase the investment.

2.桥上的电缆和电线不能放在同一个槽里。原因：两种导线的允许温度不同，导线的绝缘层比较薄，容易被电缆拉断。电线的机械强度不好，所以干脆把电缆弄断。

2. Cables and wires on the bridge cannot be placed in the same slot. Reason: the allowable temperature of the two conductors is different, and the insulation layer of the conductor is relatively thin, which is easy to be broken by the cable. The mechanical strength of the wire is not good, so just break the cable.

3.不同类型的电缆不应敷设在同一线槽内，主要是因为工作温度不一致，如VV系列65度和YJY系列90度。如果敷设在同一线槽内，耐低温电缆会加速绝缘老化。

3. Different types of cables should not be laid in the same trunking, mainly because the working temperature is inconsistent, such as VV series 65 degrees and yjy series 90 degrees. If laid in the same trunking, low temperature resistant cables will accelerate insulation aging.

4.线槽内敷设的电缆容量应根据同一线槽内的电缆数量、敷设环境温度等进行考虑。一般来说，电缆的额外容量应考虑在百分之60百分之80之间，而塑料线槽由于散热不佳，可考虑在百分之50百分之70之间。

4. The cable capacity laid in the trunking shall be considered according to the number of cables in the same trunking, laying ambient temperature, etc. Generally speaking, the additional capacity of the cable should be considered between 60% and 80%, while the plastic trunking can be considered between 50% and 70% due to poor heat dissipation.

5.由于其特殊的结构（内部增加了防火棉和防火板），防火桥架的内部空间比一般的桥梁框架要小，所以在选择时要注意电缆的占地面积比。由于散热条件差，电缆负载流量可视为额外电缆负载流量的百分之40百分之60。恒重比一般的桥重。规划固定支吊架时，不能设定钢桥规划中规定的距离，但应增加密度。根据规划的桥架的大小，建议选择1-1.5米的距离。

5. Due to its special structure (fireproof cotton and fireproof board are added inside). The internal space of the fireproof bridge is smaller than that of the general bridge frame, so pay attention to the floor area ratio of the cable when selecting. Due to poor heat dissipation conditions, the cable load flow can be regarded as 40% to 60% of the additional cable load flow. The constant weight is heavier than that of the general bridge. When planning the fixed supports and hangers, the regulations in the steel bridge planning cannot be set Set the distance, but increase the density. According to the size of the planned bridge, it is recommended to choose a distance of 1-1.5m.

以上就是如何正确使用山东电缆桥架的以及五点注意事项。虽然桥架的发展在我们的生活中起着关重要的作用，但如何正确使用桥架，以及使用桥架的注意事项，这是一个管理者应该注意的问题。

The above is how to correctly use Shandong cable tray and five precautions. Although the development of bridge plays a vital role in our life, how to use the bridge correctly and the precautions for using the bridge are a problem that managers should pay attention to.

济南电缆桥架防火等级的选择和保养方法电缆桥架如今应用广泛，随着近几年电缆桥架的普及，越来越多的人开始注意到了电缆桥架，想要从中获取更多关于电缆桥架的日常知识，下面，济南电缆桥架厂为大家详细介绍一下电缆桥架防火等级的选择以及保养方法，希望能帮助到你！

Selection and maintenance methods of fire rating of cable tray in Jinan cable tray is now widely used. With the popularity of cable tray in recent years, more and more people begin to pay attention to cable tray and want to obtain more daily knowledge about cable tray. Next, Jinan cable tray factory will introduce the selection and maintenance methods of fire rating of cable tray in detail, Hope to help you!

一、电缆桥架防火等级选择：

1、 Selection of fire rating of cable tray:

在有防火要求的地段，济南电缆桥架可通过在电缆梯、桥架内添加防火或阻燃板、网等材料，形成封闭或半封闭结构，并采取在桥架及其支吊架表面涂防火涂料等措施。整体耐火性能应满足相关规范或标准的要求。在防火要求高的地方，不应使用电缆桥架。

In sections with fire protection requirements, Jinan cable tray can form a closed or semi closed structure by adding fireproof or flame retardant plates, nets and other materials in the cable ladder and tray, and take measures such as coating the surface of the tray and its supports and hangers with fire retardant coating. The overall fire resistance shall meet the requirements of relevant national codes or standards. Cable trays shall not be used in places with high fire protection requirements.

在相同规格下，阻燃电缆桥架比钢制电缆桥架贵2.2倍，使用寿命是钢制电缆桥架的5倍以上，重量比钢制电缆桥架重百分之30。其使用寿命是钢制电缆桥架的三倍多，重量与钢制电缆桥架基本相同。

Under the same specification, flame retardant cable tray is 2.2 times more expensive than steel cable tray, its service life is more than 5 times that of steel cable tray, and its weight is 30% heavier than steel cable tray. Its service life is more than three times that of steel cable tray, and its weight is basically the same as that of steel cable tray.

二、电缆桥架的定期维护：

2、 Regular maintenance of cable tray:

1.一般来说，电缆桥架可以每季度维护一次。用软布擦去表面的灰尘后，用一种特殊的蜡抛光剂均匀地擦拭表面，过一会儿再用一块干净的软布抛光，这是防潮的。五金配件和金属手柄可以用较少的机油擦拭和干燥，因此它们可以灵活旋转，防锈和抗氧化。

1. Generally speaking, the cable tray can be maintained once a quarter. After wiping the dust off the surface with a soft cloth, wipe the surface evenly with a special wax polishing agent, and then polish with a clean soft cloth after a while, which is moisture-proof. Hardware fittings and metal handles can be wiped and dried with less engine oil, so they can rotate flexibly, prevent rust and resist oxidation.

2.避免放置在湿热的地方，保持房间通风干燥。

2. Avoid placing in hot and humid places and keep the room ventilated and dry.

3.避免与腐蚀性液体接触，如酒精和指甲油。

3. avoid contact with corrosive liquids such as alcohol and nail polish.

4.应使用干净的软布和专用保养蜡。

4. Clean soft cloth and special maintenance wax shall be used.
