Description

Technical Field

[0001] The invention relates to the field of line fixing structures, in particular to a power transmission and transformation line fixing device. Background Art

[0002] The transmission of electric current often leads to losses due to heating of the line, so during transmission, the voltage is increased through transformers to reduce the current and reduce the heat loss. High voltage electricity is very dangerous, and the target electrical appliances do not need such high voltage, which requires the voltage to be reduced through transformers. Since multiple transformers are required during the transmission of current, the transmission of current is called transmission and transformation. During the laying of transmission and transformation line wires, in order to make the wires occupy the correct position, fixtures are needed to fix the outside of the wires. Transmission and transformation line fixtures are important components in the power system used to support and fix transmission lines, substation equipment and their ancillary facilities.
