A second waterproof tape 22 is arranged at the bottom end of the lead-brazing 21.

[0024] Working principle:

[0025] First step, during use, the porcelain bushing body 11 itself is a good electrical insulating material, which can isolate the cable conductor 13 from the external environment, prevent current leakage and short circuit, and ensure the safety and stability of power transmission. At the same time, the porcelain bushing body 11 is connected to the mounting plate 28. At the top of the mounting plate 28, a second top ring 32 and a plug rod 33 are installed. The second top ring 32 is butt-mounted with the end of the porcelain bushing body 11. The second top ring 32 fits the end of the fixed sleeve 25, and the second top ring 32 is inserted into the interior of the positioning port 29. The second top ring 32 plays a supporting role for the porcelain bushing body 11. At the same time, a first top ring 31 is installed at the top of the mounting plate 28. The first top ring 31 and the second top ring 32 together play a supporting role for the porcelain bushing body 11. At the same time, a pre-tightening sleeve 27 is fixedly installed at the bottom of the mounting plate 28. The pre-tightening sleeve 27 is fixedly installed with the end of the porcelain bushing body 11. The pre-tightening sleeve 27 cooperates with the second top ring 32 to increase the contact surface, share the gravity of the porcelain bushing body 11 itself, weaken the radial force generated between the porcelain bushing body 11 and the mounting plate 28, and prevent deformation of the end of the porcelain bushing body 11 due to force.

[0026] Second step, the porcelain bushing body 11 uses ceramic materials, mainly to provide insulation effect, prevent breakdown or arc phenomenon between the internal high-voltage conductor and the outer shell or other conductive objects. The corrugated design on the surface of the porcelain bushing body 11 can increase the heat dissipation area, improve the heat dissipation efficiency, and prevent overheating. At the same time, a cable conductor 13, a semi-conductive tape 14, and a first waterproof tape 15 are installed inside the porcelain bushing body 11. The internal conductive part is usually made of copper or aluminum, with excellent electrical conductivity. The conductor connects the high-voltage power supply and the load, and transmits current during operation. At the same time, the porcelain bushing ensures that it is well insulated to prevent current leakage.

[0027] The sealing components include a sealing sleeve 17, a metal sheath 19, a second waterproof tape 22, and an outer sheath 23. These components are usually located at the interfaces or connections of the terminal, mainly used to provide airtight and waterproof functions, prevent external moisture and pollutants from entering the interior, ensure the interior remains dry and clean, and thus maintain the stability of electrical performance. The mounting plate 28 is used to firmly install the entire porcelain bushing body 11 terminal on the equipment or fix it in the system structure, ensuring its structural integrity and stability under the action of earthquakes, vibrations or other mechanical forces. The grounding cable 24 can be used in cooperation with the mounting plate 28 to be reliably connected to other power equipment or the ground wire, providing electrical isolation and mechanical support.
