[0020] Example 1

[0021] Reference Figures 1-2 An environmentally friendly insulating bushing structure for incoming and outgoing lines in a ring main unit includes an insulating sleeve 1, a rotating sleeve A2, a rotating sleeve B3, two insulating sleeve mounting plates 4, and two rotating seats 5. The insulating sleeve 1 has a corrugated cross-section and is ductile. Both ends of the insulating sleeve 1 are fixed to one side of the two insulating sleeve mounting plates 4, and the two rotating seats 5 are respectively installed on the other side of the two insulating sleeve mounting plates 4 and rotatably connected to the insulating sleeve mounting plates 4. A first through hole 4-1 is provided in the middle of the insulating sleeve mounting plate 4, and a second through hole 5-1 is provided in the middle of the rotating seat 5. The rotating sleeve A2 and the rotating sleeve B3 are respectively installed on the two rotating seats 5 and pass through the two first through holes 4-1. An annular groove 2-1 is provided at one end of the rotating sleeve A2. The annular groove 2-1 is a threaded groove. An annular connecting post 3-1 is provided at one end of the rotating sleeve B3. The annular connecting post 3-1 is threadedly connected to the annular groove 2-1.

[0022] Preferably, an annular groove 5-2 is provided on one side of the rotating seat 5, and a slider 4-2 is provided on the insulating sleeve mounting plate 4. The slider 4-2 is located in the annular groove 5-2 and can slide freely in the annular groove 5-2.

[0023] Preferably, the inner diameters of the rotating sleeves A2 and B3 are the same as the inner diameter of the second through hole 5-1, and the rotating sleeves A2 and B3 are concentric with the second through hole 5-1.

[0024] In actual operation, first rotate the two rotating seats 5 to bring the rotating sleeve A2 and rotating sleeve B3 close together, so that the length of the insulating sleeve 1 is minimized. Then, the line passes through the first through hole 4-1 and the second through hole 5-1 on one side, so that the insulating sleeve 1 is fitted on the line. Finally, by rotating the two rotating seats 5, the rotating sleeve A2 and rotating sleeve B3 are separated. At this time, the separated insulating sleeve mounting plate 4 will stretch the insulating sleeve 1 to both ends, so that the insulating sleeve 1 is gradually straightened from a wavy shape, which reduces the width and increases the creepage distance.

[0025] Example 2

[0026] Reference Figure 3 The difference between this embodiment and embodiment one is that the outer periphery of the rotating seat 5 is provided with anti-slip texture 5-3.
