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.
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.
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.
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. Material difference: There are many types of cable tray materials on the market, and you can choose according to your own situation,
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.
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.
Fiberglass bridge frames have excellent aging resistance, long service life, no recycling value, and are not easily lost.
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.
Steel cable trays: Steel trays are also divided into hot-dip galvanized trays, galvanized trays, and fire-resistant spray plastic trays.
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.
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.
