山东电缆桥架虽然是低压配电设备中简单的一种产品，但是它具有品种全、应用广、结构轻、造价低、外形美观的特点，给技术改进、电缆扩充、维护检修带来方便，在工程中得到广泛应用，每年的用量相当大。

Although cable tray in Shandong is a simple product of low-voltage distribution equipment, it has the characteristics of complete variety, wide application, light structure, low cost, and beautiful appearance. It brings convenience to technical improvement, cable expansion, maintenance and overhaul, and is widely used in projects, with a considerable amount of consumption every year.

根据制造桥架的材料，桥架一般分为钢制电缆桥架、阻燃玻璃钢电缆桥架、抗腐蚀铝合金电缆桥架、防火电缆桥架四大类。根据桥架的结构形式，桥架一般分为槽式电缆桥架、托盘式电缆桥架、梯阶式电缆桥架、组合式电缆桥架、大跨距电缆桥架五大类。这些也是目前在国内应用比较多的桥架，多为封闭型桥架。

According to the materials used to manufacture the cable tray, the cable tray is generally divided into four categories: steel cable tray, flame retardant fiberglass cable tray, corrosion resistant aluminum alloy cable tray, and fire resistant cable tray. According to the structural form of cable tray, cable tray is generally divided into five categories: trough type cable tray, tray type cable tray, ladder type cable tray, combined cable tray, and long-span cable tray. These are also the bridges that are widely used in China, mostly enclosed bridges.

槽式电缆桥架是一中全封闭型电缆桥架，它适用于敷设计算机电缆、通信电缆、热点偶电缆及其他高灵敏系统的控制电缆的屏蔽干扰和重腐蚀环境中电缆的保护。

The trough type cable tray is a fully enclosed cable tray, which is suitable for laying computer cables, communication cables, hot couple cables and control cables of other highly sensitive systems to shield interference and protect cables in heavily corrosive environments.

托盘式电缆桥架具有质量轻、载荷大、安装方便等优点，它既适用于动力电缆的安装，也适用于控制电缆的敷设。梯阶式电缆桥架适用于直径大电缆的敷设，特别适用高、低压动力电缆的敷设。

Tray type cable tray has the advantages of light weight, large load, convenient installation, etc. It is suitable for the installation of power cables and the laying of control cables. Ladder type cable tray is suitable for laying large diameter cables, especially for laying high and low voltage power cables.

组合式电缆桥架能够根据安装场所的实际情况，随意组合，适用于安装环境较为复杂，对桥架走线槽空间变化有较多要求的场合。

The combined cable tray can be combined at will according to the actual situation of the installation site, and is suitable for occasions where the installation environment is more complex and there are more requirements for the space change of cable tray trunking.

大跨距电缆桥架受安装场所条件限制，不能设置较多托臂、吊架、要求桥架必须要有较大支吊跨距的场合。

The large span cable tray is limited by the installation site conditions, so it is not allowed to set many corbels and hangers. It is required that the bridge must have a large span of supports and hangers.

选择桥架需要考虑两个重要指标：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，电缆桥架应能适用不同的环境要求和有较长的适用寿命。电缆桥架的承载能力是通过选择适当厚度的材料来满足，环境要求和适用寿命是通过选择相应的原材料来满足。

Two important indicators need to be considered when selecting cable tray: the bearing capacity of cable tray should meet the requirement that the working uniform load is less than the rated uniform load, and cable tray should be able to meet different environmental requirements and have a long service life. The bearing capacity of cable tray is met by selecting materials with appropriate thickness, and the environmental requirements and applicable life are met by selecting corresponding raw materials.

为了提高电缆桥架的承载能力，一般是增加桥架的板材厚度来实现的；而环境要求则是重腐蚀环境一般选用玻璃钢或者铝合金作为生产电缆桥架的主体材料，常规腐蚀环境一般选用钢质材料作为生产电缆桥架的主体材料，而钢质电缆桥架根据桥架的耐腐蚀等级又分别采用热浸镀锌，热固体粉末静电喷塑、喷漆、电镀锌等表面处理方式。更多事项就来我们网站 //www.comprepyme.com咨询了解吧！

In order to improve the bearing capacity of cable tray, it is generally realized by increasing the plate thickness of the bridge; The environmental requirement is that glass fiber reinforced plastic or aluminum alloy is generally used as the main material for cable tray production in heavily corrosive environment, and steel material is generally used as the main material for cable tray production in conventional corrosive environment, while steel cable tray adopts hot dip galvanizing, hot solid powder electrostatic spraying, painting, galvanization and other surface treatment methods according to the corrosion resistance grade of the bridge.
