Description

Technical Field

[0001] The utility model relates to the technical field of pin-type porcelain insulators, in particular to a pin-type porcelain insulator with double anti-loosening function. Background Art

[0002] Insulators are used to support conductors. Insulators can ensure that the conductors, crossarms, and towers have sufficient insulation. They should be able to withstand the vertical load and horizontal tension of the conductors during operation. Therefore, insulators must have both good electrical performance and sufficient mechanical strength. The quality of the fixing method of the insulator is very important for the safe operation of the line. Insulators include butterfly insulators, suspension insulators, pin insulators, etc. The traditional method of fixing the conductor of the pin insulator is to use binding wires and aluminum tape to fix the conductor in the wire groove at the top of the pin insulator. This method is not only physically demanding, but also takes a long time to fix and disassemble, and it is easy to damage the conductor. In addition, in actual work, the fastening nut at the bottom of the pin insulator will also loosen due to mechanical vibration caused by wind, electromagnetic vibration generated during operation, and rust. If not handled in time, the conductor will slide onto the crossarm, causing a line accident. Therefore, we have introduced a pin porcelain insulator with double anti-loosening. Utility Model Content
