FRP cable tray elbows are important accessories in cable tray systems, mainly used to change the orientation of cable trays to adapt to different installation environments and layout requirements. The following is a detailed introduction about it:

Characteristics

Strong corrosion resistance: Composed of materials such as glass fiber reinforced plastic and flame retardants, it has extremely high corrosion resistance and can be used in highly corrosive environments such as chemical engineering, metallurgy, and petroleum.

Good fire resistance and heat insulation: The selected material has a low thermal conductivity and flame retardants are added, making the elbow not only have fire resistance and heat insulation but also self-extinguishing properties, effectively preventing the spread of fire.

Lightweight structure: Light in weight, it is convenient for transportation and installation, and also reduces the load-bearing burden of the building.

High strength: It has a relatively high mechanical strength, capable of withstanding the weight of cables and external pressure, ensuring the stability of the cable tray system.

Flexible design: Elbows of various angles and sizes can be customized according to actual needs, such as the common 45° and 90° elbows, as well as vertical upper elbows, vertical lower elbows, horizontal inner elbows, horizontal outer elbows, and reducers, etc., to meet the requirements of different wiring scenarios.

Production and installation

Production process

Design: Based on the engineering requirements and installation scenarios, determine the shape, size and structure of the elbow to ensure compliance with relevant standards and specifications.

Prepare the mold: According to the design requirements, make or purchase the appropriate mold to shape the elbow.

Prepare materials: Select appropriate glass fiber fabric and resin as raw materials to ensure they have sufficient strength and corrosion resistance.

Apply a layer of anti-sticking agent to the surface of the mold to prevent the fiberglass reinforced plastic material from adhering to the mold.

Production: Cut the fiberglass fabric into the appropriate shape and size, soak it in resin to ensure full penetration, and then place it in a mold to compact it, making sure the material fills every corner of the mold.

Curing: Wait for the fiberglass reinforced plastic material to be completely cured according to the curing time of the selected resin.

Demolding: After the curing is completed, remove the elbow from the mold and handle it gently to prevent damage.

Processing and finishing: Carry out necessary processing and finishing on the elbow, such as removing excess material and trimming the edges, to make it meet the design requirements and appearance requirements.

Quality inspection: Conduct visual inspection, dimensional inspection and strength test, etc., to ensure that the quality of the elbow meets the standards and requirements.

Installation Points

Measurement and positioning: Before installation, it is necessary to accurately measure the direction and position of the cable tray, determine the installation position and Angle of the elbow, and ensure that it matches the layout of the overall tray system.

Connection method: The elbows of FRP cable trays are usually connected to the main body of the cable tray by means of bolt connection or snap connection, etc. When connecting, it is necessary to ensure the sealing and firmness of the connection parts to prevent the cable tray from loosening or falling off during use.

Fixation and support: According to the weight of the elbow and the load of the cable, the fixed points and support structures should be reasonably set to ensure the stability of the elbow during operation and avoid deformation or damage caused by uneven force.
