Illustrate the utility model using process below in conjunction with accompanying drawing.

The use is determined according to the angle between the HGIS equipment or the columnar switch connector and the horizontal, and the required outlet angle. When the outlet angle is required to be 30 degrees, and the angle between the HGIS equipment or the columnar switch joint and the horizontal is not at any angle other than vertical, use the utility model structure shown in Figure 1 (to correct the first vertical plate 4 and the curved plate 1. The angle with the HGIS equipment or the columnar switch connector is such that the outlet of the overhead line is 30 degrees, and then the cylindrical wiring slot 3 and the U-shaped body are used to fix the overhead line; when the outlet angle is required to be horizontal, and the HGIS equipment or the columnar switch connector When the included angle with the horizontal is not at any angle other than vertical, use the structure of the utility model shown in Figure 4 to correct the angle between the bent plate 1 and the HGIS equipment or the columnar switch joint, so that the outgoing line of the overhead line is at a horizontal angle, and then cylindrical Wiring slot 3 and U-shaped body 2 are fixed to the overhead line; when the overhead line outlet angle is required to be vertical, and the angle between the HGIS equipment or the columnar switch connector and the horizontal is not at any angle other than vertical, use the The structure of the utility model is to repair the angle between the second vertical plate and the HGIS equipment or the columnar switch joint, so that the outgoing line is at a vertical angle, and then the cylindrical wiring slot 3 and the U-shaped body 2 are fixed with the overhead line.

When the angle between the HGIS equipment or the columnar switch connector and the horizontal is too large, and the second vertical plate 5, the first vertical plate 4, and the curved plate 1 cannot be used to adjust the outlet angle, on the second vertical plate 5 and the curved plate 1 Increase the angle adjustment bolt hole 6, and further correct the angle between the bent plate 1 or the second vertical plate 5 and the HGIS equipment or columnar switch joint through the angle adjustment bolt hole 6, so as to meet the 30 degree, horizontal and vertical angle of the outgoing line.

It solves the phenomenon of loose strands of wires after installation. If the HGIS equipment or the columnar switch connector is not perpendicular to the horizontal but has an included angle, according to the requirements of horizontal, 30°, and vertical outlets, using conventional clamps to fix the overhead lines is prone to inappropriate spacing and clamping angles. It is not straight and easy to twist, coupled with wind swing and external force, the phenomenon of loose strands appears in the overhead wire, which also makes the overall layout of the wire connection more perfect and more beautiful.
