许多人对镀锌电缆桥架了解不多。它与普通电缆桥架有什么区别，这也是人们一直困扰的问题。本文适合读者特别介绍镀锌电缆桥架和普通电缆桥架之间的区别。希望对大家有帮助。

Many people don't know much about galvanized cable trays. What is the difference between it and ordinary cable tray, which is also a problem that has been perplexed by people. This article is suitable for readers to introduce the difference between galvanized cable tray and ordinary cable tray. I hope it will help you.

1、电缆桥架厂的长度限制偏差

1. Length limit deviation of cable tray factory

当长度小于,等于2000毫米,正负2毫米的偏差;

When the length is less than or equal to 2000mm, the deviation of plus or minus 2mm;

B)大于2000毫米,长度时的偏差的正负4毫米。

B) Greater than 2000 mm, the length deviation is plus or minus 4 mm.

2、的尺寸公差根据GB / T1804 - V。

2. The dimensional tolerance shall be in accordance with GB / T1804 - V.

注意:浴缸宽度取负偏差,采取积极偏差盖板宽度。

Note: negative deviation shall be adopted for the width of bathtub, and positive deviation shall be adopted for the width of cover plate.

3、电缆桥架表面平面度公差:

3. Flatness tolerance of cable tray surface:

)热镀锌电缆桥架平面度公差每平方米重量不超过8毫米;

）The flatness tolerance of hot-dip galvanized cable tray shall not exceed 8mm per square meter;

B)或锌合金电镀和喷涂增加平面度公差米电缆托盘不大于4毫米。

B) Or zinc alloy plating and spraying to increase the flatness tolerance, and the cable tray shall not be more than 4mm.

注:电缆槽宽度小于一米计算计。

Note: the width of cable tray is less than one meter.

4通气孔:一个洞底部的托盘底部的通风面积不得超过总面积的40%。

4 vent: the ventilation area at the bottom of the tray at the bottom of a hole shall not exceed 40% of the total area.

5电缆桥架铁路:级联式电缆桥架铁路距不应大于300毫米;铁路的宽度应不少于30毫米。

5 cable tray Railway: the distance between cascaded cable tray and railway shall not be greater than 300mm; The width of the railway shall not be less than 30 mm.

镀锌电缆桥架

Galvanized cable tray

1.镀锌电缆桥架的特点：

1. Features of galvanized cable tray:

由于被称为特殊和特征，镀锌电缆桥架自然具有普通电缆桥架所没有的功能。那就是耐腐蚀性。镀锌电缆桥架具有出色的防腐性能，因此可以在许多特殊场合中轻松使用，并且建造的建筑物使用更长。例如，在某些与水接触的区域中，尤其是在像桥这样的水旁存在水的情况下，周围的空气将不可避免地具有较高的水蒸气含量。因此，这时，镀锌电缆桥架的耐蚀性为。其优点得以显现。

As it is called special and characteristic, galvanized cable tray naturally has the function that ordinary cable tray does not have. That is corrosion resistance. Galvanized cable tray has excellent anti-corrosion performance, so it can be easily used in many special occasions, and the built buildings can be used longer. For example, in some areas in contact with water, especially when there is water next to water such as bridges, the surrounding air will inevitably have a high water vapor content. Therefore, at this time, the corrosion resistance of galvanized cable tray is. Its advantages appear.

2.耐火性：

2. Fire resistance:

此外，浇铸镀锌电缆桥架时，将在表面上铺上一层较厚的耐火层。因此，铸造镀锌电缆桥架在普通电缆桥架的基础上具有一定的耐火性，这进一步扩大了镀锌电缆桥架的应用范围。

In addition, when casting galvanized cable tray, a thick refractory layer will be laid on the surface. Therefore, the cast galvanized cable tray has certain fire resistance on the basis of ordinary cable tray, which further expands the application range of galvanized cable tray.
