Profit=sales revenue, cost, tax, and related management expenses. It can be seen that under a certain sales revenue, only by reducing costs, taxes, and related management expenses can profit be increased. Among them, taxes cannot be reduced, and the reduction of related management expenses is achieved through the good operation of the enterprise's quality management system. The article explores the feasibility of improving product profits by reducing costs. Of course, the prerequisite for reducing costs is to maintain the quality level of the product.

成本主要是由原材料成本和制造成本组成，制造成本包括生产设备成本、生产过程中人力资源成本等。设备投资是必须的，工人工资是不能随意降低的，可见制造成本的降低幅度是有限的，因此只能在降低原材料成本上想办法，可是，降低原材料成本又不能降低产品质量水平，这就必须进行技术革新，寻求新的生产技术和产品形式。

The cost mainly consists of raw material costs and manufacturing costs, including production equipment costs, human resource costs during the production process, etc. Equipment investment is necessary, and workers' wages cannot be arbitrarily reduced. It can be seen that the reduction in manufacturing costs is limited, so we can only find ways to reduce raw material costs. However, reducing raw material costs cannot lower the level of product quality. Therefore, technological innovation must be carried out to seek new production technologies and product forms.

前面提到，电缆桥架的两个重要指标：电缆桥架的承载能力应满足工作均布载荷小于额定均布载荷，电缆桥架应能适应不同的环境要求和有较长的使用寿命。因此，应该从这两方面来考虑如何降低成本。

As mentioned earlier, the two important indicators of cable trays are: the bearing capacity of the cable tray should meet the requirement that the working uniform load is less than the rated uniform load, and the cable tray should be able to adapt to different environmental requirements and have a longer service life. Therefore, we should consider how to reduce costs from these two aspects.

首先，从电缆桥架的承载能力方面考虑。降低电缆桥架的成本，首先就是降低所用板材的厚度，如何使电缆桥架选用低厚度板材满足原有承载能力要求，或选用原有厚度板材满足更高承载能力要求将是解决这个问题的关键。下面，针对不同的电缆桥架进行具体分析：

Firstly, consider the bearing capacity of the cable tray. To reduce the cost of cable trays, the first step is to reduce the thickness of the plates used. The key to solving this problem is to choose low thickness plates for cable trays to meet the original load-bearing capacity requirements, or to choose original thickness plates to meet higher load-bearing capacity requirements. Below, specific analysis will be conducted for different cable trays:

(1)钢制电缆桥架。因为型材的结构强度要高于普通的平面板材，因此可以使用机拉或压制工艺，改变电缆桥架的平面板材形状，以提高强度。例如将电缆桥架主体结构中底板、帮边、盖板均采用瓦楞结构，或压制出类似履带的块状凹凸结构，使电缆桥架的强度增大。同时散热面积增大，其构造便于透气和热交换，也降低了电缆桥架内敷设电缆的能量损耗。该种结构选用低厚度板材即可满足原有承载能力要求，这将大量降低原材料的使用量。目前，这两种工艺均有电缆桥架厂家进行了尝试，且都有较好的使用效果。如果沿着这个方向进一步研究，将来应该还会有更加新型的电缆桥架产生。

(1) Steel cable tray. Because the structural strength of the profile is higher than that of ordinary flat plates, machine drawing or pressing processes can be used to change the shape of the flat plate of the cable tray to improve its strength. For example, the bottom plate, edge, and cover plate in the main structure of the cable tray are all corrugated structures, or a block like concave convex structure similar to a track is pressed to increase the strength of the cable tray. At the same time, the heat dissipation area increases, and its structure facilitates ventilation and heat exchange, while also reducing the energy loss of cables laid inside the cable tray. This structure can meet the original load-bearing capacity requirements by selecting low thickness plates, which will greatly reduce the use of raw materials. At present, both of these processes have been tried by cable tray manufacturers, and both have achieved good results in use. If further research is conducted in this direction, there should be even more new types of cable trays in the future.

另外，对于内敷设电缆较少、电缆较轻的场所，可以采用钢网制造替代钢质板材，该种结构装配灵活，适用于各种安装情况，便于空气流通且能有效减少电磁干扰的影响。这种钢网电缆桥架极大地降低了原材料的使用，有效地控制了原材料成本。

In addition, for places with fewer cables and lighter cables, steel mesh manufacturing can be used instead of steel plates. This structure is flexible in assembly, suitable for various installation situations, convenient for air circulation, and can effectively reduce the impact of electromagnetic interference. This steel mesh cable tray greatly reduces the use of raw materials and effectively controls the cost of raw materials.
