Q: cable tray turned down slope how do
A: bottom bridge length after bending (bottom oblique ) to the same length as the width of the tray , but the scope is controlled at 100-400mm, the length of the selected period of two points drawn on the tray relative to the side wall and the bottom side of the two vertical lines , the selected direction of curvature as the cutting bridge the opening side ; selected as the bottom opening side , with two vertical lines are drawn as the parting line two isosceles triangles , these waist base of the triangle to determine the length of the formula L = 2 × ( bridge height × sin22.5 °), a simple algorithm based on 100 high bridge , for example, an isosceles triangle base length 76.5mm, namely 100:76.5 , followed by proportional analogy 150,200 high bridge isosceles bottom bend length change , this ratio is also suitable for horizontal 90 ° elbow restructuring ; this isosceles triangle cut after using the tool , you can get two curved bridge formed by 45 ° bend 90 ° elbow bridge . As for the length of the bridge restructuring elbow limited , as long as the use of junior learned simple mathematical knowledge to calculate the distance of any length can be controlled . A simple calculation using mathematical methods , a variety of angles , the length of the elbow can be produced .
Q: How to fix the cable in horizontal bridge
A: As for the single , each loop a group banding together, the level of the bridge allowed no space to install, do not differ between circuits are fixed . Filling rate not greater than 40 % can. Should be single trunk cable , otherwise serious derating
Q : FRP cable tray maximum span is how much ?
A: Generally FRP bridge maximum supported distance is 6 m .
