許多人對(duì)鍍鋅電纜橋架了解不多。它與普通電纜橋架有什么區(qū)別，這也是人們一直困擾的問(wèn)題。本文適合讀者非常介紹鍍鋅電纜橋架和普通電纜橋架之間的區(qū)別。希望對(duì)大家有幫助。

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、電纜橋架廠的長(zhǎng)度限制偏差

1. Length limit deviation of cable tray factory

當(dāng)長(zhǎng)度小于,等于2000毫米,正負(fù)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,長(zhǎng)度時(shí)的偏差的正負(fù)4毫米。

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

2、的尺寸公差根據(jù)GB / T1804 - V。

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

注意:浴缸寬度取負(fù)偏差,采取積出色偏差蓋板寬度。

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

3、電纜橋架表面平面度公差:

3. Flatness tolerance of cable tray surface:

)熱鍍鋅電纜橋架平面度公差每平方米重量不超過(guò)8毫米;

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

B)或鋅合金電鍍和噴涂增加平面度公差米電纜托盤不大于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:電纜槽寬度小于一米計(jì)算計(jì)。

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

4通氣孔:一個(gè)洞底部的托盤底部的通風(fēng)面積不得超過(guò)總面積的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電纜橋架鐵路:級(jí)聯(lián)式電纜橋架鐵路距不應(yīng)大于300毫米;鐵路的寬度應(yīng)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.

鍍鋅電纜橋架

Galvanized cable tray

1.鍍鋅電纜橋架的特點(diǎn)：

1. Features of galvanized cable tray:

由于被稱為特殊和特征，鍍鋅電纜橋架自然具有普通電纜橋架所沒(méi)有的功能。那就是耐腐蝕性。鍍鋅電纜橋架具有出色的防腐性能，因此可以在許多特殊場(chǎng)合中輕松使用，并且建造的建筑物使用更長(zhǎng)。例如，在某些與水接觸的區(qū)域中，尤其是在像橋這樣的水旁存在水的情況下，周圍的空氣將不可避免地具有較高的水蒸氣含量。因此，這時(shí)，鍍鋅電纜橋架的耐蝕性為。其優(yōu)點(diǎn)得以顯現(xiàn)。

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，澆鑄鍍鋅電纜橋架時(shí)，將在表面上鋪上一層較厚的耐火層。因此，鑄造鍍鋅電纜橋架在普通電纜橋架的基礎(chǔ)上具有一定的耐火性，這進(jìn)一步擴(kuò)大了鍍鋅電纜橋架的應(yīng)用范圍。

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.
