玻璃鋼電纜橋架基礎(chǔ)知識

玻璃鋼電纜橋架的優(yōu)缺點(diǎn)
    部分客戶對玻璃鋼電纜橋架了解不多，以下是編輯為大家整理的一些關(guān)于玻璃鋼電纜橋架的資料，詳細(xì)了解可以聯(lián)系客戶。
    玻璃鋼電纜橋架的優(yōu)點(diǎn)有：一、生產(chǎn)方便快捷、生產(chǎn)效率較高。二、采用專業(yè)模具、精度較高，外形尺寸一致性較好。三、與其它材質(zhì)電纜橋架相比，價格較低。四、橋架采用分體式組裝成型，配置較靈活，便于組織生產(chǎn)。
     玻璃鋼電纜橋架的缺點(diǎn)：一、強(qiáng)度低，承載能力差。單純的玻璃鋼電纜橋架的強(qiáng)度全靠產(chǎn)品內(nèi)部的玻璃纖維，與其它材質(zhì)相差甚遠(yuǎn)，采用分體式結(jié)構(gòu)，各部分之間用螺栓或柳釘組裝二成，在搬運(yùn)、安裝甚至使用過程，不可避免會產(chǎn)生螺栓松動，造成橋架強(qiáng)度降低或者損壞。二、強(qiáng)度單向性。產(chǎn)品中只有縱向的紗織，沒有橫向的紗織，因此產(chǎn)品縱向的強(qiáng)度較高，但橫向的強(qiáng)度卻很差。三耐熱性不高。四耐腐蝕性不強(qiáng)。
     常見的三種玻璃鋼電纜橋架：
     一、環(huán)氧樹脂復(fù)合型玻璃鋼電纜橋
     環(huán)氧樹脂復(fù)合型玻璃鋼電纜橋架在環(huán)氧樹脂電纜橋架內(nèi)增加了金屬骨架，增加了機(jī)械強(qiáng)度，可承載大直徑的電纜，橋架跨度可達(dá)到12米，在金屬層與非金屬層之間增加了結(jié)合層解決金屬層與非金屬層膨脹系數(shù)不同引起的脫層。在電纜橋架表面模壓了具有抗光照等特殊作用的保護(hù)層；環(huán)氧樹脂復(fù)合型玻璃鋼電纜橋架使用壽命超過三十年，比較適合腐蝕性強(qiáng)，大跨度、重載荷的環(huán)境。
     二、玻璃鋼拉擠電纜橋架
    玻璃鋼拉擠電纜橋架采用國內(nèi)外較為先進(jìn)的玻璃鋼拉擠工藝，機(jī)械化連續(xù)生產(chǎn)，因此不僅完全具有國內(nèi)通行的橋架的優(yōu)點(diǎn)，而且產(chǎn)品尺寸穩(wěn)定，并可以任意選定，長度可超過8米，具有更高的強(qiáng)度、剛度和耐腐蝕性。
     三、玻璃鋼模壓電纜橋架
    玻璃鋼模壓電纜橋架是將玻璃鋼纖維和樹脂放在模具中，在一定壓力和溫度下固化成型、模壓橋架具有防腐蝕強(qiáng)，阻燃強(qiáng)度大、表面光潔，結(jié)構(gòu)復(fù)雜的也也可以一次性成型。
    以上是關(guān)于玻璃鋼電纜橋架的基礎(chǔ)知識，具體選用什么類型的電纜橋架，要結(jié)合使用環(huán)境，電纜要求，使用年限，經(jīng)濟(jì)條件等綜合因素來考慮。

Advantages and disadvantages of FRP cable bridge
Some of the customers do not know much about the fiberglass cable bridge. The following are some information about the FRP cable bridge.
The advantages of FRP cable tray are as follows: first, the production is convenient and efficient, and the production efficiency is high. Two, the use of professional mold, high precision, good consistency in shape and size.  Three. Cable bridge with other materials
Compared, the price is lower. Four. The bridge frame is divided into two parts, which is more flexible and easy to organize production.
The shortcomings of FRP cable tray are as follows: 1. Low strength and poor carrying capacity. The strength of the FRP cable bridge depends solely on the glass fiber inside the product, which is far from other materials.
The split type structure is assembled with bolts or willow nails for 20%. In the process of handling, installation and even use, it is inevitable that the bolt is loosened and the strength of the bridge is reduced or damaged. Two, strength
One way. The product has only longitudinal yarn and no transverse yarn, so the longitudinal strength of the product is higher, but the transverse strength is very poor. Three the heat resistance is not high. Four corrosion resistance is not strong.
Common three kinds of fiberglass cable bridge:
Epoxy resin composite fiberglass cable bridge
The epoxy resin composite fiberglass cable bridge increases the metal skeleton in the epoxy cable bridge, increases the mechanical strength, and can carry large diameter cable. The span of the bridge can reach 12 meters.
A bonding layer is added between the metal layer and the non-metallic layer to solve the delamination caused by the expansion coefficient of the metal layer and the non-metallic layer. The protective layer with special functions such as light resistance is molded on the surface of the cable tray.
The epoxy resin composite FRP cable bridge has a life span of more than thirty years, and is suitable for the environment with strong corrosion, large span and heavy load.
Two, FRP pultrusion cable bridge
Glass steel pultrusion cable bridge adopts more advanced glass steel pultrusion technology at home and abroad, and it is mechanized continuous production. Therefore, it not only has the advantages of the domestic bridge, but also the product size is stable.
It can be arbitrarily selected, with a length of more than 8 meters, with higher strength, rigidity and corrosion resistance.
Three, fiberglass molded cable bridge
Glass fiber reinforced plastic cable bridge is to put fiberglass fiber and resin in the mold. Under certain pressure and temperature, the solidified and molded bridge has a strong anticorrosion and corrosion resistance, the flame retardancy is large, the surface is smooth and the structure is smooth.
The complex can also be molded in one time.
The above is the basic knowledge of FRP Bridge, and what type of cable bridge is selected, which should be considered in combination with the use of environment, cable requirements, service life, economic conditions and other comprehensive factors.
