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.

槽式橋架：它的外形猶如盒子相同，是一種徹底關閉型的電纜橋架，因為屏蔽作用非常好，所以一般應用于信號較大的環境下。

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.

梯式橋架：梯式橋架的外形就跟一把梯子相同，它是一款由國內外材料研制而成的新式電纜橋架，在散熱、本錢、裝置等方面比較有優勢。

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.

托盤式橋架：他的外觀其實跟槽式橋架大同小異，僅有一點差異就是托盤式它是一種半密封型的橋架，底部帶有孔以便散熱。

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、材質的區別：市面上電纜橋架材質有很多種，大家可以根據自己的情況去選擇，

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

玻璃鋼材質：玻璃鋼橋架是通過拉擠工藝、用無堿、無捻、無蠟的纖維紗浸潤樹脂后，通過高溫模具固化成型而生產出來不的。其中加入適量的鋁粉，起到質輕、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.

其主要的特點就是耐腐蝕極強，能在酸堿等強腐蝕、潮濕的環境中使用。具有很有的阻燃性，并且防靜電，不導電。

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.

玻璃鋼橋架具有很好的耐老化、壽命長、沒有回收價值、不易丟。

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

環氧樹脂復合型電纜橋架：復合橋架是中間為鋼骨架（內襯鋼板），兩側為復合環氧樹脂防腐層的一種橋架。

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.

鋼制電纜橋架：鋼制橋架還分為熱浸鋅橋架、鍍鋅橋架、防火噴塑橋架。

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

聚氨酯電纜橋架：聚氨酯橋架復合電纜橋架是采用進口聚氨酯樹脂，無堿纖維紗等各種優良原料、采用封閉型模具注射工藝、經過一次性拉擠固化成型。

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.

聚氨酯復合電纜橋架特點：產品壁厚、重量輕、阻燃性能高、拉擠、抗壓、抗彎曲、抗沖擊強度是優統拉擠產品的3倍、耐腐蝕性能好、使用壽命為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.
