玻璃钢电缆桥架的优缺点
    部分客户对玻璃钢电缆桥架了解不多，以下是编辑为大家整理的一些关于玻璃钢电缆桥架的资料，详细了解可以联系客户。
    玻璃钢电缆桥架的优点有：一、生产方便快捷、生产效率较高。二、采用专业模具、精度较高，外形尺寸一致性较好。三、与其它材质电缆桥架相比，价格较低。四、桥架采用分体式组装成型，配置较灵活，便于组织生产。
     玻璃钢电缆桥架的缺点：一、强度低，承载能力差。单纯的玻璃钢电缆桥架的强度全靠产品内部的玻璃纤维，与其它材质相差甚远，采用分体式结构，各部分之间用螺栓或柳钉组装二成，在搬运、安装甚至使用过程，不可避免会产生螺栓松动，造成桥架强度降低或者损坏。二、强度单向性。产品中只有纵向的纱织，没有横向的纱织，因此产品纵向的强度较高，但横向的强度却很差。三耐热性不高。四耐腐蚀性不强。
     常见的三种玻璃钢电缆桥架：
     一、环氧树脂复合型玻璃钢电缆桥
     环氧树脂复合型玻璃钢电缆桥架在环氧树脂电缆桥架内增加了金属骨架，增加了机械强度，可承载大直径的电缆，桥架跨度可达到12米，在金属层与非金属层之间增加了结合层解决金属层与非金属层膨胀系数不同引起的脱层。在电缆桥架表面模压了具有抗光照等特殊作用的保护层；环氧树脂复合型玻璃钢电缆桥架使用寿命超过三十年，比较适合腐蚀性强，大跨度、重载荷的环境。
     二、玻璃钢拉挤电缆桥架
    玻璃钢拉挤电缆桥架采用国内外较为先进的玻璃钢拉挤工艺，机械化连续生产，因此不仅完全具有国内通行的桥架的优点，而且产品尺寸稳定，并可以任意选定，长度可超过8米，具有更高的强度、刚度和耐腐蚀性。
     三、玻璃钢模压电缆桥架
    玻璃钢模压电缆桥架是将玻璃钢纤维和树脂放在模具中，在一定压力和温度下固化成型、模压桥架具有防腐蚀强，阻燃强度大、表面光洁，结构复杂的也也可以一次性成型。
    以上是关于玻璃钢电缆桥架的基础知识，具体选用什么类型的电缆桥架，要结合使用环境，电缆要求，使用年限，经济条件等综合因素来考虑。

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.
