有关电缆桥架各部件名称及功能说明，立柱和托臂是电缆桥架安装的两个主要部件，介绍了铝合金电缆桥架、梯形电缆桥架、有孔托盘、无孔托盘等的功能。

About the name and function description of each component of cable tray, the column and bracket are the two main components of cable tray installation. This paper introduces the functions of aluminum alloy cable tray, trapezoidal cable tray, perforated tray, non perforated tray, etc.

电缆桥架安装时的支托，是通过立柱和托臂来完成的。立柱是支撑电缆桥架的主要部件；而桥架的荷重是通过托臂传递给立柱的。因此，立柱和托臂是电缆桥架安装的两个主要部件。

The support of cable tray installation is completed through the column and support arm. The column is the main component supporting the cable tray; The load of the bridge is transmitted to the column through the bracket. Therefore, the column and bracket are the two main components of cable tray installation.

1、铝合金电缆桥架：铝合金制电缆桥架装置的简称，由铝合金材料制作托盘或梯架的直通弯通附件以及支吊架等构成用以支承电缆具有连续刚性结构的总体装置。

1. Aluminum alloy cable tray: the abbreviation of aluminum alloy cable tray device, which consists of straight elbow accessories and supports and hangers made of aluminum alloy materials to support cables with continuous rigid structure.

2、梯形电缆桥架：梯形电缆桥架直接承托电缆的部件的简称，由两根纵向侧边与若干根横档构成的梯形部件。

2. Trapezoidal cable tray: the abbreviation of the part of trapezoidal cable tray that directly supports cables. It is a trapezoidal part composed of two longitudinal sides and several rungs.

3、有孔托盘：有孔槽形电缆桥架直接承托电缆的部件的简称，由带孔眼的底板和侧边所构成的或由整块铝合金板冲孔后弯曲制成底部有孔的槽形部件。

3. Perforated tray: it is the abbreviation of the part of the perforated trough cable tray that directly supports the cable, which is composed of the bottom plate with holes and the side, or the trough part with holes at the bottom is made by punching and bending the whole aluminum alloy plate.

4、无孔托盘：无孔槽形电缆桥架直接承托电缆的部件的简称，由底板与侧边构成的或由整块铝合金板弯曲制成实底的槽形部件。

4. Non perforated tray: short for the part of non perforated trough cable tray that directly supports cables. It is a trough shaped part composed of bottom plate and side or made of a solid bottom by bending a whole piece of aluminum alloy plate.

桥架是自行设计制造的一种抗腐蚀桥架。它具有结构简单、式样新颖、耐腐蚀，安装维护方便，不需保养等特点，能够适用于广泛的环境条件。

The cable tray is a kind of corrosion-resistant cable tray designed and manufactured by ourselves. It has the characteristics of simple structure, novel style, corrosion resistance, convenient installation and maintenance, no maintenance, and can be applied to a wide range of environmental conditions.

桥架按结构形式可分为LQJ-A、B、C型和LQJ-LPC型，前者分别采用不同截面形状的铝合金挤压型材加工桥架邦板和梯档，可制成梯级式、托盘式、槽式结构以满足不同场合的需要，后者采用铝板折边成型，制成槽式汇线槽及各类特殊弯通，以满足电缆布线的需要。

According to the structural form, the bridge can be divided into lqj-a, B, C and lqj-lpc types. The former uses aluminum alloy extruded profiles with different cross-section shapes to process the bridge bond plate and ladder rungs, which can be made into stepped, tray and trough structures to meet the needs of different occasions. The latter uses aluminum plate folding to form, which is made into trough trunking and various special bends to meet the needs of cable wiring.

LQJ-A、B、C型铝合金挤压型材加工成型后固溶和人工时效处理，不仅提高了耐蚀性，而且提高了铝合金的强度，从而保证铝合金桥架具有较高的承载能力。 济南电缆桥架表面经阳极氧化处理，使其更具有优异的耐蚀性、具有耐腐蚀时间长、不需要保养的优点，特别适用于高温、高湿、富盐雾的环境中选用。

The solid solution and artificial aging treatment of lqj-a, B and C aluminum alloy extruded profiles after processing and forming not only improve the corrosion resistance, but also improve the strength of the aluminum alloy, so as to ensure that the aluminum alloy bridge has a high bearing capacity. The surface of Jinan cable tray is anodized, which makes it have excellent corrosion resistance, long corrosion resistance time and no maintenance. It is especially suitable for the environment with high temperature, high humidity and rich salt fog.
