How to distinguish between high and low voltage power cables
5 °), a simple algorithm is 100 high bridge, for example, isosceles triangle bottom length of 76
The bottom edge of the bridge after bending (bottom bevel) and the width of the bridge can be the same length, but the range is controlled at 100-400mm, select the length of the two points, in the bridge side to help out on the side Two vertical lines, selected bridge bending direction as the cutting opening side; open the opening side as the bottom edge to draw the two vertical lines were used as two isosceles triangle in the sub-line, the waist triangle Edge length of the formula for the L = 2 × (bridge height × sin22
5mm, that is 100: 76 followed by the proportion of push The height of the isosceles triangle at the time of the bend of the 200 high bridge is also suitable for the adjustment of the 90 ° bend; the use of the tool is cut off and the bending of the bridge is 90 ° Bridge elbow As for the length of the bridge to limit the restructuring of the elbow, as long as the use of junior high school learned by the simple mathematical knowledge of the calculation, any length distance can be controlled The use of mathematical methods simple calculation, a variety of angles, the length of the elbow can be made zuo
