應(yīng)用自然環(huán)境不一樣，必須挑選的橋架規(guī)格、型號(hào)規(guī)格都不一樣，這也就牽涉到電纜橋架的購(gòu)買難題。一般，挑選和選購(gòu)電纜橋架，只必須留意下列4個(gè)關(guān)鍵點(diǎn)。

The natural environment is different, and the cable tray specifications, models and specifications that must be selected are different, which also involves the purchase of cable tray. Generally, the following four key points must be paid attention to when selecting and purchasing cable trays.

1、挑選適合的結(jié)構(gòu)特征

1. Select appropriate structural features

濟(jì)南電纜橋架的種類關(guān)鍵和構(gòu)造相關(guān)，不一樣構(gòu)造的電纜橋架運(yùn)用在不一樣的自然環(huán)境中。因而，先要依據(jù)實(shí)際的工程施工自然環(huán)境和所希望的電纜橋架的作用來(lái)挑選好的電纜橋架。

The type of cable tray in Jinan is related to its structure. Cable trays with different structures are used in different natural environments. Therefore, it is necessary to select a good cable tray according to the actual natural environment of the project construction and the desired role of the cable tray.

2、依據(jù)材料挑選電纜橋架

2. Select cable tray according to material

電纜橋架有鋼質(zhì)、玻璃鋼防腐和鋁合金型材等幾類種類，不一樣原材料制成的電纜橋架在特性上各有不同。例如玻璃鋼橋架重量較輕；鋁合金橋架凈重也輕，但價(jià)錢偏貴。

Cable trays include steel, glass fiber reinforced plastic anti-corrosion and aluminum alloy profiles. Cable trays made of different raw materials have different characteristics. For example, the weight of FRP Bridge is light; The net weight of aluminum alloy bridge is also light, but the price is too expensive.

3、依據(jù)阻燃等級(jí)挑選電纜橋架

3. Cable tray shall be selected according to flame retardant grade

如果是對(duì)防火有較高規(guī)定的自然環(huán)境，不宜應(yīng)用鋁合金橋架，而應(yīng)當(dāng)挑選阻燃性型電纜橋架，那樣能夠確保電纜橋架的使用壽命更長(zhǎng)。

If it is a natural environment with high regulations on fire safety, aluminum alloy cable tray should not be used, but flame retardant cable tray should be selected, which can ensure a longer service life of cable tray.

4、挑選電纜橋架規(guī)格

4. Select cable tray specification

濟(jì)南電纜橋架不可以稍大或偏小，一定要挑選適合的規(guī)格。整體的標(biāo)準(zhǔn)是，電纜線總截面與拖盤內(nèi)橫斷總面積的比率，電纜電纜不可超過(guò)40%；變頻電纜不可超過(guò)50%。

Jinan cable tray can not be slightly larger or smaller, we must select the appropriate specifications. The overall standard is that the ratio of the total cross-section of the cable to the total cross-sectional area in the tray shall not exceed 40%; The frequency conversion cable shall not exceed 50%.
