How do you know the detection method of the trolley line?
1. Between the trolley wire and the flexible cable, the insulation resistance between each ground must be greater than 0.5MΩ.
Test method: Use a rocker test, or check the test record.
2. The distance between the centerline of the trolley wire and the actual centerline of the crane track and the horizontal or vertical distance between the brackets of the same trolley must be consistent. The deviation value should not be greater than 1/1000, and the maximum should not exceed 10mm.
3. The slide wire is fixed and reliable on the insulator. The sliding wire connection is smooth and the sliding surface is strictly prohibited from corrosion. . Com and wire connections must be tin plated or galvanized.
Inspection method: observation and inspection.
4. There are no cracks and defects in the insulator, and the gaskets between the cleaning and the bracket are complete. The brackets are flat, firm, evenly spaced and uniform in paint color. The bolts of the connecting bolts expose the nuts 2 to 3 buckles.
