I don't know how much you know about cable tray. Cable tray is a kind of building material commonly used in the electrical industry. It can protect the cable from external factors and ensure the safety of our electricity use. It's an assistant to us and the cable line, so to speak. Cable tray is laid inside the cable, it can make the installation of electrical appliances to a beautiful standard requirements, and we only need to open the cover in the maintenance, very convenient. Now let's learn how to choose the material of cable tray in Jinan. Let's have a look.
1. Jinan cable tray is a fully enclosed high strength rectangular steel pipe processed with good steel plate. The appearance is treated with zinc plating, which greatly improves the corrosion resistance. The inside and outside of the bridge should be smooth and flat without edges and corners, and there should be no distortion, warpage and other deformation phenomena.
2. Junction box and socket box: in the wiring plane, it is used for turning and connecting wires. Intersection is the intersection of the envelope, which can be transformed into different pipe shapes and adjusted in a certain range of height.
Isolation board is set in the distribution box of double bridge line to ensure the isolation and shielding between strong current and weak current. When the strong and weak current transmission on the laying plane is very complex, the bridge adopts the deepening of horizontal position, and the junction box crosses the bridge in the horizontal direction, which greatly facilitates the direction of various lines.
3. Special outlet: it is used to lead out wires, and can be used as the outlet of power supply, telephone, Video Jack or computer terminal if necessary. An outlet is set 230mm away from the junction box, and the standard spacing between outlets is 600mm. If it is a double bridge frame, the distance between two adjacent groups is 1400mm.
4. Connecting supporting accessories: straight connection uses circular pipe connector of connector; round pipe connection of junction box uses reducing joint; connection of rack and pipe uses terminal; bracket and adjusting bolt are used for support and height adjustment. The length of adjusting bolt varies according to construction conditions. S-shaped depth special joint with height adjustment of 30 ~ 50mm is used for vertical and horizontal crossing or cross beam passing through The horizontal curve is used for the corner of the bridge, the longitudinal bending is used for the upper and lower joint of the bridge, and the special adhesive for other bridges is used for the connection between the bridge and the bridge, and between the bridge and the wiring box.
The above is the content of Jinan cable tray material selection, the above content is introduced, I hope this article can help you, follow-up you want to know more about relevant knowledge, consultation can continue to pay attention to our official website.
