1. Type: There are many types of cable trays, and the three commonly used cable trays are: trough type tray, ladder type tray, and tray type tray.

槽式桥架：它的外形犹如盒子相同，是一种彻底关闭型的电缆桥架，因为屏蔽作用非常好，所以一般应用于信号较大的环境下。

Slot type cable tray: It has the same appearance as a box and is a completely closed cable tray. Due to its excellent shielding effect, it is generally used in environments with high signals.

梯式桥架：梯式桥架的外形就跟一把梯子相同，它是一款由国内外材料研制而成的新式电缆桥架，在散热、本钱、装置等方面比较有优势。

Ladder type cable tray: The appearance of the ladder type cable tray is the same as that of a ladder. It is a new type of cable tray developed from domestic and foreign materials, which has advantages in heat dissipation, cost, and installation.

托盘式桥架：他的外观其实跟槽式桥架大同小异，仅有一点差异就是托盘式它是一种半密封型的桥架，底部带有孔以便散热。

Tray type bridge: Its appearance is actually similar to slot type bridge, with only one difference being that the tray type is a semi sealed bridge with holes at the bottom for heat dissipation.

2、材质的区别：市面上电缆桥架材质有很多种，大家可以根据自己的情况去选择，

2. Material difference: There are many types of cable tray materials on the market, and you can choose according to your own situation,

玻璃钢材质：玻璃钢桥架是通过拉挤工艺、用无碱、无捻、无蜡的纤维纱浸润树脂后，通过高温模具固化成型而生产出来不的。其中加入适量的铝粉，起到质轻、阻燃的作用。

Fiberglass material: Fiberglass cable trays are produced through a pultrusion process, using alkali free, twist free, and wax free fiber yarns soaked in resin, and then solidified and formed through high-temperature molds. Adding an appropriate amount of aluminum powder has a lightweight and flame retardant effect.

其主要的特点就是耐腐蚀极强，能在酸碱等强腐蚀、潮湿的环境中使用。具有很有的阻燃性，并且防静电，不导电。

Its main characteristic is its strong corrosion resistance, which can be used in strong corrosive and humid environments such as acid and alkali. It has high flame retardancy, and is anti-static and non-conductive.

玻璃钢桥架具有很好的耐老化、寿命长、没有回收价值、不易丢。

Fiberglass bridge frames have excellent aging resistance, long service life, no recycling value, and are not easily lost.

环氧树脂复合型电缆桥架：复合桥架是中间为钢骨架（内衬钢板），两侧为复合环氧树脂防腐层的一种桥架。

Epoxy resin composite cable tray: A composite tray is a type of cable tray with a steel skeleton (lined with steel plates) in the middle and a composite epoxy resin anti-corrosion layer on both sides.

钢制电缆桥架：钢制桥架还分为热浸锌桥架、镀锌桥架、防火喷塑桥架。

Steel cable trays: Steel trays are also divided into hot-dip galvanized trays, galvanized trays, and fire-resistant spray plastic trays.

聚氨酯电缆桥架：聚氨酯桥架复合电缆桥架是采用进口聚氨酯树脂，无碱纤维纱等各种优良原料、采用封闭型模具注射工艺、经过一次性拉挤固化成型。

Polyurethane cable tray: The polyurethane cable tray composite cable tray is made of various excellent raw materials such as imported polyurethane resin and alkali free fiber yarn. It adopts a closed mold injection process and is formed through one-time extrusion and solidification.

聚氨酯复合电缆桥架特点：产品壁厚、重量轻、阻燃性能高、拉挤、抗压、抗弯曲、抗冲击强度是优统拉挤产品的3倍、耐腐蚀性能好、使用寿命为50年左右。

Characteristics of polyurethane composite cable tray: product wall thickness, light weight, high flame retardancy, extrusion, compression resistance, bending resistance, and impact strength are three times that of Youtong extrusion products, good corrosion resistance, and a service life of about 50 years.
