Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power transmission and distribution line, specifically to a kind of power transmission and distribution line wire fixing device. BACKGROUND

[0002] The delivery of current often leads to loss due to line heating, so during delivery, the voltage is raised by power transformation to reduce the current and heat loss. High-voltage electricity is highly dangerous, and the target appliance does not need such high voltage, which requires power transformation to reduce the voltage. Since power transformation is required multiple times during current delivery, the current delivery is referred to as power transmission and distribution.

[0003] The installation of the line often requires external fixing devices for fixation. The existing patent No. CN111987672A discloses an assembled wire fixing structure, which adjusts the fixed position of the wire by rotating the main and auxiliary threaded handles, moving the main and auxiliary fixed plates through the main and auxiliary threaded rods, and inserting the main and auxiliary insertion plates into the main and auxiliary slots to make the wire fixed in the main and auxiliary grooves more stable.

[0004] However, when the device moves relative to the wire, it is prone to wear and tear, and has poor reliability. UTILITY MODEL CONTENT
